Show HN: AI tool to that reaches top in machine-learning competition (github.com)

I've been experimenting with autonomous coding agents for ML workflows. ML-Ralph uses claude-code to run a continuous experiment loop - it forms hypotheses, writes training code, evaluates results, and iterates on what it learns. Added Weights & Biases integration for observability on long runs. As a test, I pointed it at Kaggle Higgs Boson and let it run for a few hours unsupervised. It placed top 30. I humanly participated on that competition too, and barely reached top 150.

Still rough around the edges. Would appreciate feedback, especially on failure modes you'd want to see handled better.
