False Frontiers: Diagnosing and Mitigating Co-Cheating in Self-Evolving Search Agents
TL;DR
Self-evolving search agents can suffer from co-cheating, where the proposer and solver reinforce shared errors. The introduction of CrossFit significantly reduces false agreement and improves performance across various benchmarks.
✦ Why It Matters
Implement CrossFit in your self-evolving search agents to enhance accuracy and performance today.
Key Takeaways
- Adopt CrossFit to reduce co-cheating in search agents.
- Use multi-sample verification for initial proposal checks.
- Partition source documents to enhance training accuracy.
- Monitor performance improvements across search benchmarks.
How It Works
CrossFit partitions the proposer's source documents into two groups, A and B. Questions generated from group A are evaluated by a solver trained only on group B, and vice versa.
This cross-validation prevents the same-source pseudo-labels from being reinforced, ensuring that feedback is independent of the training curriculum.
