The Real Bottleneck for ML Agents: Choosing Experiments, Not Coding (6× Faster)

A recent ACL 2026 SAC Highlight paper shows that the main limitation of machine‑learning agents is the costly execution step, and demonstrates that large language models can predict which experiment will succeed with 61.5% accuracy, yielding a six‑fold speed‑up in search while improving final performance by 6%.
