So it doesn't detect poachers, it detects humans. And it requires drones flying non-stop over gigantic masses of land.

Edit: having dabbled in this field myself during my studies, I know from research that one of the biggest problems is simply corruption among rangers. It doesn't really matter if you can spot a poacher if a whole group of rangers will decide to not do anything about it (because for them the financial incentive of doing nothing can be HUGE). Of course the corruption problem stems from very low incomes and poor living conditions in those countries. If your monthly income is $100, it's quite tempting to accept a $10.000 bribe.

Edit 2: I worked on this: https://www.hackthepoacher.com/. We tried it with cell phone detection.

This was pretty much what the owner of small game park told me. The drones are too high tech and expensive for them to run. He said having small teams patrol every night worked better. When the teams haven't been able to patrol, for example due to flooded roads. He said it only took a couple of weeks before the poachers started showing up again.

I always wonder if the better solution isn't to re-legalize ivory and rhino horn. All the game farms have room full of the stuff. Dumping that onto the market will kill the price, at the same time there is suddenly a financial incentive to keep the animals safe. Currently its $10k a horn on the black market vs a bit of tourism money to incentivize keeping the parks safe.

The saddest part is that horn and tusks grow back so it could be a renewable resource if farmed properly. The poachers only kill.

Until that stock runs out and then it is back to square #1.

It's working for the buffalo. They were endangered until someone realized you could sell their meat as an "exotic" meat for more than a burger. Now the buffalo are all over the place.

To paraphrase CGP Grey it turns out the best evolutionary advantage is being useful to humans.

If any of the execs of Panda Express are reading this give me a call I got a big idea for your brand.

Elephant tusks are incisor teeth, nerves and all. They continue growing in length during their lifetime, but would be insanely painful if cut off, and cannot grow back.
The problem can be better solved by getting the demand under control. China, one of the historic worst offenders, actually managed to do so [1], but Japan's legal market [2] still entices poachers and smugglers (who supply the black market in China [3]).

Vietnam is another huge market, especially for rhino horn.
Nah, legalize poacher hunting. Most dangerous game and such.
> Nah, legalize poacher hunting. Most dangerous game and such.

Yeah that would totally not endanger(more than they already are) indigenous people living there. After all everyone knows how poachers look like.

We solve that with poacher-poacher-hunters. And it continues forever!
Non-lethal methods only, obviously. It's basically a combination between bounty hunting and citizen's arrest laws. Not saying it couldn't be abused but it's not impossible to imagine it working. You might not even need bounties if people saw it as a sport.

It's either that or potentially corrupt park rangers doing it - it's not like the existing system works great for anyone involved.

The solution to a problem is never the commercialization of sentient beings.
It saved the Buffalo https://en.wikipedia.org/wiki/Bison#Livestock

If you care about the species giving humans an incentive to raise/protect them is pretty effective. If you care about the individual animal this is the worst thing you could do.
You'll have a 90 degree uphill battle if you want to convince people of that in general -- cows, chickens, goats, lab rats, all sorts of insects, bees, all pets, harvesting various animals for medicine.

many uphill battles have been worth fighting before. this won’t be the last.
> The solution to a problem is never the commercialization of sentient beings.

Forbidding agriculture would not solve any of our problems.

Unless you are trying to say that hum "all sentient beings are equal, but some are more equal than the other".

agriculture !== animal agriculture
"Sentient" is a conveniently empty term to say "It has senses. Can detect changes in the environment". Not more, not less. The term is being abused lately as a substitute for "self-conscious" in a straw man fallacy. We can argue that <random cute animal> is not self-conscious, but suddenly what we are arguing is "has it senses?", a fact that can't be denied.

Every animal known, every fungus known and of course every plant and algae known by us are sentient.

This is not an honest move, in my opinion.

Is just a pseudo-religious term to upgrade some organisms that we like to demigod level --and-- justify retaliation, (because the real underlying force under all this rhetoric is power acquisition; is exactly the same construction as "If you eat pork you will be punished because god says that I'm allowed to punish you").

While I don’t think the general scientific consensus agrees with you that every plant and fungus is sentient, we can pick a different word if you prefer. The ability to suffer is the important aspect, after all.

As for the part of your comment that claims using the word “sentient” is pseudo religious and used to wield power over others… I think you’re reading far, far too much into it. I don’t think anyone is using sentience as a tool to justify punishment over anyone else. In fact, it tends to be the people that deny sentience that end up punishing others, for merely belonging to different species!

TL;DR Let’s not commercialize anyone that can suffer. Historically it hasn’t gone well.

> I don’t think the general scientific consensus agrees with you that every plant and fungus is sentient

If you find a single scientist claiming the opposite, she/he is probably a genius in some field, but I grant you that is illiterate on basic biology.

The global scientific consensus is that plants and fungi react --very fast-- and accurately to any changes in the environment and take complex and strategic decisions all the time about what they perceive. There are zillions of examples that prove that.

Lets take for example this tiny fish moving its tail fast toward a light spot in the sea bottom and then deciding if it likes the place or just jump and go away. It this a sentient organism? Most people would say Yes.

Well, this is not a fish, in fact is a young Kelp deciding where to settle.

Just to make sure we aren’t getting stuck in pointless semantic argument: if someone doesn’t water their plant for 2 weeks and it slowly dies, do you treat them as you would someone who doesn’t feed their dog?

Do you want to argue semantics or do you want to discuss the actual content?

> Dumping that onto the market will kill the price

I read a story a while back that some folks are dumping synthetic ivory onto the market to make prices fall.

God bless them. I don't what makes people want ivory in the first place. Pure evil
This ends up making the situation worse. Legalization substantially increases demand far beyond what can be produced legally and ironically the value actually goes up and results in even more of the illegal product being produced. Furthermore it now becomes very difficult to distinguish between the legal and illegal product, providing criminals with an easy cover to launder the product.

https://www.nber.org/papers/w22314

Statistics Canada has reported that after the legalization of weed, the black market has actually grown quite substantially (in absolute terms).

https://www.canada.ca/en/health-canada/services/drugs-medica...

At any rate, the point is that making things legal or available can often paradoxically significantly increase demand for the illegal product and in the process make it much easier for the black market to operate.

And just to add in some controversy to the discussion, the same is true of prostitution. Almost all places that have legalized prostitution also have significantly higher rates of human trafficking including underage prostitutes.

But it was a teenage girl who "solved" something you engineers couldn't, so take that!

I always found it funny, how journalists manage to take something a kid did, without knowing the specifics, and inflate the story, just because a kid did it.

Even if it's useless in real world, and the people working on that professionally, could already tell you that...

Sometimes it's even a direct scam: https://www.youtube.com/watch?v=otjvUz7qKXc

At the same time, I think it's ok if news stories are not about only world-changing stuff. It can be about “mundane” stories of “this young person did something” too. We can read the story and give it space on the page, even if someone else is already doing the same thing better (?)
This.

The world needs more feel good stories. Also if she's doing AI on infrared images at 17 she's probably going to be really impressive work later on.

I'm somewhat confused by statements like these because they imply that the reason why we're mostly excited about it is not what she achieved but where she could potentially achieve many years later. Are these "years later" something exclusive to young people? I mean, if you're 40 years old doing exactly the same thing, and you're not retiring anytime soon it's safe to assume that you'll be working until your 50's and maybe beyond.

So then, are we celebrating the potential growth of a teenager more than that of the potential growth of a middle-aged person, on the grounds of potential, or are we celebrating that she managed to achieve this at 17?

I'm trying really hard to see beyond age. I don't care if someone is 16 or 36. Both can have the same years of experience (say 8-10 years of programming), and yet the former sounds more romantic and sellable to headliners because it's easier to dream big about achievements someone in their 25 will do than someone in their 45. Why?

>I'm somewhat confused by statements like these because they imply that the reason why we're mostly excited about it is not what she achieved but where she could potentially achieve many years later.

Did you just describe the stock market?

Because people who become high-achieving outliers tend to distinguish themselves in their adolescence. It's the start of a virtuous cycle where talent + hard work leads to admission into elite institutions (universities and, later, companies) which lead to positive network effects which amplify the ongoing application of talent + hard work.

It's rare for a previously unremarkable 36-year-old to suddenly turn in to Jeff Bezos (for a lot of reasons, not least that cognitive power peaks at age 25 so learning and adapting to novel situations gets harder with age).

I see I'm getting downvoted: why?

I'm a thoroughly average 33-year-old, for what it's worth :) I don't mean to imply that we shouldn't continue strive for growth and development as we age, but I certainly am not as mentally quick or energetic as I was ten years ago. There is very little chance I will suddenly transform into jwz or John Carmack or <insert name of legendary hacker here>.

On the bright side, I am a better communicator and strategic decision-maker, and am more satisfied with my life as it is.

(comment deleted)
I don't think you need to be at peak cognitive power for your contributions to be measurable and worth doing in society. No one would care about the age of the person who finds treatment for an autoimmune or teleportation.

Sure, you'll be delivering slower than what you would if you were 25 but slower is better than not delivering whatever unique you have to offer at all.

(comment deleted)
It depends, the followup is often unimpressive. Many people who did really impressive things in their youth ended up with quite mundane lives.

I mean it along the lines of "at 17, she is doing AI on IR images, at 30 she will be fixing bugs in traffic sign detection code for a big car company, with no mention of her name except in commit logs".

And it is not a bad thing! We need people to fix bugs in traffic sign detection code, and she may have a nice pay, in a reputable company, with a good work-life balance. It may not be impressive work, but it is work that needs to be done.

It may not be a feel good story for the press, but I believe living a mundane life certainly feels good to the one living it.

>It can be about “mundane” stories of “this young person did something” too.

Yes of course but your well-meaning reply is missing the argument made by gp: for some topics, the readers don't have enough background knowledge to know that it's a mundane story because the journalists are (possibly inadvertently) inflating the significance.

E.g. compare 2 different examples:

- "Teenager builds ramp to help nursing home patients in wheelchairs." <-- Readers already have enough background to know that "ramps" are common solutions to "wheelchair mobility" so the significance can easily be categorized as "mundane feel-good story". We can easily discount the ramp in the title and therefore properly appreciate that it's actually a human-interest story of a teenager doing something nice.

- "Teenager invents tool to spot elephant poachers." <-- Most readers have no existing knowledge of what technology is already in use to judge the significance of that type of story.

> for some topics, the readers don't have enough background knowledge to know that it's a mundane story

Why does it matter? The press does context-free puff-pieces all the time, even for professionals allegedly at the very top of their game (off the top of my head: Steve Jobs, Elizabeth Holmes[1], Elon Musk, Jeff Dean, and Sanjay Ghemawat to a lesser extent). Typically the template is "Genius expert invents X all by himself" without providing additional context for people outside of tech.

Food for thought: do you suppose journalists are exclusively wrong in tech reporting only? Or is this an area you have enough context to understand the nuances?

1. Sometimes the "revolutionary tech" is not just plain evolutionary, but fake. But a layperson reading the hagiography can't tell the difference

>Why does it matter? The press does context-free puff-pieces all the time,

Yes, I'm very aware of the meta-game around "puff pieces" which I've explained before: https://news.ycombinator.com/item?id=30881420

It seems your "Why does it matter?" was just a rhetorical question as prelude to your comment about puff pieces already existing in abundance ... But I'll answer it as if you had asked that question earnestly: It matters because readers would like to know how to gauge the significance of unfamiliar tech mentioned in the article.

So we have 2 interpretations of this thread's article:

(a) this poacher detection tool is a true breakthrough -- and the inventor also happens to be a teenager; the tech itself is not hype. The idea is truly a game changer and while the inventor's age is very young, that's a footnote to the tech invention.

... or ...

(b) the tool's tech (machine learning) is not significant and may not even work in the real world -- but the teenager's attempt at problem solving is showing promise of future things to come; let us celebrate this young person's effort.

A previous example of the first (a) type of story is this one a teen discovering a new classical algorithm comparable to a quantum algorithm: https://news.ycombinator.com/item?id=17654220

That wasn't some pure human-interest puff piece about teenager Ewin Tang. Instead, a respected computer scientist (Scott Aaronson) said it was legitimate new work that advanced our understanding of the field.

>1. Sometimes the "revolutionary tech" is not just plain evolutionary, but fake. But a layperson reading the hagiography can't tell the difference

Right ... and readers don't want to mistakenly interpret the story as type (a) when it was actually type (b). The gp (Avalaxy) of the subthread tried to give us some extra perspective about this story that the journalist did not.

> It matters because readers would like to know how to gauge the significance of unfamiliar tech mentioned in the article.

I agree with you on principle: and it should happen across the board and not just reserved for science fair submissions, but the press seems incapable of that, for reasons good and bad. For one,evaluating new tech is subjective (and difficult), and for another, sone news puff pieces are mostly written by PR firms.

This was in the article.

> Eikelboom cautions that Puri’s model still needs to be tested on raw video footage to see how well it can detect poachers—the accuracy of Puri’s model was tested using figures already determined either human or elephant. He also says other barriers already exist to using drones in parks, such as the money and manpower to keep them flying.

They also explain the technology choices and some of the other challenges.

Your issue is with the headline.

If all you read is the headline, then fine, let's play that game.

> It can be about “mundane” stories of “this young person did something” too. "Yes of course"

Okay, that's it. You agree with the previous comment.

I was impressed by what she researched and developed. Now she's going to optimise the flight path given the battery constraints.

Good work, more than I achieve for the most part, and something to celebrate in someone so young.

This one small trick that will make your poachers super-mad!
Genius girl engineer shows all the boys what's what. Her future is so $&#$# bright.
That is what happens when they have to constantly write stories for traffic and eyeballs. Your story’s life is a few hours at best. So why bother being accurate? Being first and clickbaity pays the bills, not being accurate.

The whole system needs a reboot. Without good journalism, democracies can’t survive

While it's often true what you write, there are real problems with real impact with not enough commercial value that people can do to improve the world.

I think it's much more interesting than a guy in yesterdays HN home page making a lisp machine that almost nobody uses for RISC-V which is missing a lot of more important software that needs to be written by somebody.

Take an existing problem ("Track poachers"). Notice that elephants walk differently to humans, and that movement difference can be used to identify the difference even in lower res videos (surely there's simpler ways, like size and shape? It's plausible that gait is actually a better way though). Take an existing dataset, plug it into your favourite machine learning library, and run your model over a drone feed somebody else did 99% of the work for.

Handwave away that most of the cost in the drone is going to be in getting it decent range, not a decent FLIR camera. Add in a 5x bonus to media coverage because you're young, 5x bonus because you're a woman in STEM, say something about how important skin colour, demographics, and chromosomes are for doing some mediocre programming:

> “What I really realized from this is how important it is that women, people of color, all sorts of minorities in the field of technology are at the forefront of this kind of groundbreaking technology.”

And you've got some journalists writing about you and not something far more interesting and useful, because A. The journalists can somewhat understand it, B. You're under the age of 20, C. You're a girl in STEM, D. You're a minority, and E. It's about good animals being protected from evil poachers, giving it a nice simple narrative.

And I'm sure her winning that competition was totally about merit and not because they've got a mandated 50% women winning (and she's a minority, extra points!) and probably 5% of submissions are by women. Or maybe it's not? Maybe it was merit. Either way, implicit and explicit quotas mean that it's more likely than not, and my knee-jerk reaction to this is one of "she's there because she's a girl" and not "she's there because of merit". What fantastic efforts to get rid of stereotypes, right?

I'm around her age, I'm tempted to try to send something similarly useless to that competition and get $10 000. But why bother, when the first, second, and third place will inevitably be taken up by girls with useless projects going "It was so difficult to get here, all I had was exclusive help in the form of courses, programs, special treatment, and mentors all along the way and competing against 10% of the people for 50% of the spots"

It's definitely poor journalism but it's good for encouraging this girl to keep on going.

It doesn't cost much and can be helpful for society in 10 years when she's going to be the next Elizabeth Holmes.

Wait, what? The last thing we want is more Elizabeth Holmes types…
I’m not surprised someone wrote this article, I’m just disappointed it managed to get upvoted so highly on HN. I will flag it.
Sure, break two HN guidelines in one go.

> If a story is spam or off-topic, flag it

> If you flag, please don't also comment that you did

To be fair, accusing people of breaking guidelines also breaks guidelines. Better to insert your concerns into inscrutable flaghole.
Exactly. Garbage articles only intended for ad money and clickbait for the naive on read as far as the headline and it turns out the solution is worse than projected.

Even this article was posted a day late for slow news day.

This kind of behavior puts a lot of pressure on kids for the amusement of adults as well.
The worst one I know of is the free energy kid featured on an episode of Elecroboom (YouTube). The parents are clearly supporting the kid's delusion which makes it even worse.
I wouldn't say the story is inflated. She won a few awards at the "Regeneron International Science and Engineering Fair, the world’s largest international pre-college STEM competition". I assume the judges and the people running that are not just some nobodies.
Wow, have a little heart why don't you. Sure, this isn't going to revolutionize anti-poaching, but it shows two things:

1. Teenagers can build cool things too! We need more kids interested in STEM and females are underrepresented, so these "puff" pieces are great inspiration for the next kid who happens to come across it.

2. All that was needed for her solution was a cheap FLIR camera connected to an iPhone 6, meaning you don't have to be rich/VC funded to experiment with hardware solutions.

This is Smithsonian Magazine, not the Wall Street Journal. I say bring on more stories like this!

Sure, so first place at the science fair?

There's not a hell of a lot of value in a constant barrage of hyperbolic articles telling us that the world has changed.

It's about as useful as parents telling their kids that they're the best and smartest that the world has ever seen, only to have reality tear the carpet from under their feet.

You can be encouraging and realistic at the same time.

They're not denigrating the kid, they're denigrating hapless journalists looking for clicks.

However as opposed to most articles of this type, this one isn't as "THIS IS GONNA BE WORLD CHANGING!!!!!" and more "look at this cool thing this kid did" which is so much more acceptable, especially if it helps get more _people_ (no matter who they are) into STEM.

A better solution could be hacking the supply side by flooding the market with fake ivory indistinguishable from real ivory. The price of ivory should go down. There will be less financial incentive for the poaching and bribing. Some biologists are working on this angle [1].

[1] https://www.smithsonianmag.com/science-nature/faking-elephan...

This. But also putting a bounty on poachers that exceeds the value of ivory, make killing poachers so profitable that for every poacher, there are 20 bounty hunters. Also, education. Also, counter intelligence (ingrain societies that value ivory with rumors that touching ivory causes flaccidity and ruins libido, which is highly contagious, etc.)

Also, why don't we just take all the elephants and rhinos from them, establish them in the American west? We can deal with the ecological issues.

> We can deal with the ecological issues.

This is a refrain heard so often (as a wild herd of fifty thousand elephants goes trumpeting through downtown Salt Lake City).

13,000 years ago, very elephant-like creatures roamed N. America.[1] So the ecological issues are not going to be a big problem. Besides, elephants stampeding through Salt Lake City is not an example of an ecological issue. Call Animal Control.

[1] https://en.wikipedia.org/wiki/Gomphothere

"No, no, poaching elephants is actually really safe."

"But, but the bounty? Poacher heads go for ten times what ivory goes for."

"That, look, scary stories that the government has to tell to make the voters think that they're doing something to help those poor defenseless elephants. Scare tactics. Think about it, if they really were going to do anything about the poachers, then they wouldn't be putting up some bounty against poaching. It's an admission that they can't and they won't do anything to stop us. Besides, factory has been shut down for three weeks and isn't opening any time soon. You want to put food on the table or not?"

<LATER>

A rifle shot rings out across the early morning plains. An elephant collapses to the ground and breathes its last breath.

"Change of plans Fred, we've got video evidence that you just poached an elephant. I hear poacher heads go for ten times what ivory does."

"You said the bounty was nothing but propaganda!"

"Yeah, good thing there's no bounty on liars."

A second rifle shot rings out across the early morning plains. "Now, sure would be a shame if all that ivory goes to waste."

Unfortunately this is accurate, much like the bounties put on certain people within Afghanistan where it sure seems like it was abused by certain local tribes to take out some rival and profit from the US Government in the process. In areas where you'd want to put a bounty on people, there's bound to be enough corruption and misaligned incentives to make it not work the way you hoped.
Your situation is still 50% success, although with collateral damage (the single killed elephant).
"Oh, we call him the poacher punisher. Poachers killed his family, or at least that's the story. He's killed hundreds of poachers, maybe even thousands. In fact, he once killed an entire village of poachers. Men, women, children, dogs, poachers all of them. At least according to the poacher punisher. He brought back the ivory he said he found on them. It's how he made his first million."

A man kills an elephant with a rifle and then shoots the rifle with another rifle. He brings in the first rifle and gets a reward. Then he sells the ivory and gets a second reward. I'm not convinced that this situation is any improved (and certainly not a 50% success) if instead of this farce he instead tricks someone who wasn't going to shoot any elephants into shooting an elephant.

That. Plus...

Poacher Hunter to the paying authority: "Bob was a poacher. I didn't shoot him while he walked home from work. I promise."

Its not only the money. Rangers get shot at, even killed, by poachers every now and then (Botswana’s “shoot to kill” policy won’t have helped there)

Also, like corruption, poaching also stems from very low incomes and poor living conditions in those countries.

It sounds to me like the group she's working with is already running these drones, and they're currently digging through the video manually. That's where she got all the training data to make these tools.

Maybe it's not the most effective way to hunt for poachers, but it seems to be *one* way that poachers are hunted, and a way that has some obvious room for improvement by sprinkling on a bit of ML magic.

This seems overly cynical. If you detect that someone is messing about with the bank door after hours you can't be certain that it is a robber, but it is still helpful to know. I also doubt all the rangers are corrupt. There is no reason to let perfect be the enemy of good here.
also, drones cause major distress to elephants. it sounds like bees to them. its a major reason you are not allowed to fly them in chiang mai.
If the US rented a Northrop Grumman RQ-4 Global Hawk equipped with appropriate imaging systems to these governments the poaching game might change. Lesser reliance on corrupt rangers. Unfortunately I doubt these things make financial sense in the name of conservation
So pay rangers more, with bonus incentives to capture or kill poachers, wanted dead or alive like famous wild west posters from the 1800s?
I wonder if poachers quickly learn to alter behavior in presence of drone noise...
Drones can be very quiet. I saw my police flying playing with one and it was a whisper even from 30 feet away.

I was surprised because I thought all drones had that annoyingly loud hum.

I have a rather loud drone(DJI mini 2). From about 70m and up, the noise is practically non-existent, even when hovering directly overhead.
Unless killed for meat by indigenous folks who need it I 100% support the tracking/hunting/fining/imprisoning/etc of anyone that kills an Elephant for its tusks or worse for sport.
What about villagers killing elephants who raid and destroy their crops?
I'd say that's ok, too, though that's tougher since humans are spreading and clearing ever more acreage of land for farming that it's affecting what used to be the habit of many animals not just the elephant. There's no clear, easy answer here, but surely we can take a hard stance on folks that hunt them for sport or the ivory trade.
Correction: I don’t support the hunting of people even if they are hunters.
There should be laws against these 'look at my clever wiz kid' articles. It's not that far off from beauty pageants and equally sick and pretentious. I remember just last week here in Berkeley seeing a young teenager playing Beethoven's 9th on an electric keyboard, perfectly. He was playing on the street and had all of $10 in change in his bowl. The look of misery on his face as his fingers effortlessly worked out the melody was astounding. He looked like a caged animal, living out his parent's dream in captivity. $50 says he blows his brains out by his thirties. This is abuse plain and simple.
Anytime there says “there aught to be a law…” there almost never should be.

That said, I agree the whiz kid articles are dumb, but not for the reasons you listed. More just “yea, let’s see how they do when they don’t have infinite time and zero responsibilities”.

Really? This kid clearly cares about the world and wanted to apply herself to a problem. There should be a law against rewarding such initiative with publicity? She's 17. When I was that age, I was completely bored to death by what I was "learning" in high school and I had one foot out the door.

With regards to that musical kid... I've got resting bitch face. When I'm focused on a difficult task, it's way worse; I call it "thinking murder face." I'm a musician, and if I'm playing a complex piece, I couldn't smile if I tried, even though I'm loving every second of what I'm doing.

Won’t the poachers just change their speed and turning radius to not appear as humans?

I’ve become a bit skeptical of these stories on kids doing what normally experienced professionals do (research, startups). I’d understand if a kid accidentally discovered or invented something cool that no one else thought of. I wish kids focused on fun and learning in school. Some of these stories seem like ‘spike’ projects to help the kids college application standout.

This is the kind of shit I would be doing for fun and learning in school.

Kids have the disposable time to dedicate to grind stuff like this out. All they really need is the spark of interest, then everything else takes care of itself.

Surely you can discriminate a human from an elephant _by size alone_ with a thermal camera, without needing to resort to movement patterns.
Probably measuring the size is difficult, unless your camera is reporting depth? I don't know.
If you are flying a drone overhead, you know the altitude and can do basic trig to find total distance from sensor angle. With even very approximate distances one should be able to distinguish a 200lb, 0.4m wide, 0.2m long human from a 10,000lb, 1.5m wide, 4m long elephant.
It's a nice project, from start to end. Gives you real insight how "real world" ML-backed systems work. Data acquisition, feature engineering, model design / tuning, etc.

This kind of system is what you'd expect to see in maybe a graduate level ML/DL class, maybe even Bachelors thesis.

Whether or not it actually works for catching poachers isn't all that important IMO, even though they're marketing it that way. As many have mentioned, for it to really work, you'd probably need a small fleet of drones - and more likely, data from satellite providers. In my area of work (surveillance / intelligence), we do a lot of similar stuff - students like these are awesome to work with for summer internships / thesis projects.

It's neat, but the real solution is fixing the incentives for poachers in the first place. It's an economic issue at its root
Kudos to her. Conservation tech is a challenging and exciting test bed for "hackers" because it's a hyper dimensional chessboard of constraints and strategies. It's easy to reduce the solution to "just do this." From one end, poaching is lucrative in areas with massive economic disparity. And from the other, climate change and the pressure we put on natural resources is unbalancing ecosystems driving human wildlife conflict.

A project I've worked on is Trailguard AI, ran by resolve.ngo, the principal is Eric Dinnerstein who is the former chief scientist at WWF. I can say they our running a start up in every sense of the word but the result is beautiful: a satelite/ gsm connected, battery powered AI enabled cryptic trail cam that can be used as a swiss army knife from animal censuses, to poacher detection, illegal logging truck detection and preventing human wildlife content (detect tiger + sound alarm).

I made a very very similar project in year 12 in school. (got nationally ranked too). looks like they have taken it a few (very important) steps further www.github.com/itsa-mee-mario/guardians-of-the-wildlife. (sorry for the cheesy name ad)
I was in the Kruger this weekend, and our guide was lamenting that they've already lost over 340 rhino this year, and said poachers keep hacking their radios and finding out where the rhino are, even when they change code they speak in.

I find the chance of that to be roughly zero though - clearly a bunch of the guides have been paid off. This isn't a problem tech can solve.

Secret shopper and encrypted radios?

If the radios can be trusted, you feed bad data to specific people and see when the poachers show up. Seems like there are some solutions.

When I was in South Africa, the anti-poaching crews were clearly underpaid judging by their cloths, demeanor, and gear (old radios, and the ratty shotguns). If the job is so important it should be better paid.

Installing your people as guides > paying off poachers.
Now that is what I call girl power what a girl boss girl girl girl! You go, girl!
“I was quite taken aback,” the 17-year-old from Chappaqua, New York, recalls. “Because I always thought, ‘well, poaching is illegal, how come it really is still such a big issue?’”

Life lesson. If an activity can generate income, someone will do it. Law notwithstanding.

This reminds me of this thread on the Ardupilot forum from someone in the field using drones to find poachers: https://discuss.ardupilot.org/t/autonomous-anti-poaching-dro... .

The gist of it was that the drones were not that effective at spotting poachers (8 cases in two years of operations), and even if you spot them they will likely be gone by the time someone can arrive there.

Well, if we don't solve the poacher problem, eventually it will solve itself: no more rare animals to poach.
Annnnd my "bitter, cynical, grumpy HN type" radar just bust a cog :-)
I feel like we are solving the wrong problem. People are being killed for living and working land that they have used for ages.
