IRDS: Interpretable RLVR Data Selection via Verifier-Coupled Sparse Autoencoder Coverage
TL;DR
Researchers identified a gap in LLM evaluation benchmarks. They built a synthetic dataset with 10k adversarial prompts targeting reasoning failures.
✦ Why It Matters
Use this benchmark to audit LLM robustness before deploying in production reasoning pipelines.
Key Takeaways
- Utilize IRDS for efficient data selection in RLVR tasks.
- Leverage sparse autoencoders to improve model interpretability.
- Focus on training instances where models can learn despite failures.
- Achieve significant cost savings compared to traditional methods.
How It Works
IRDS employs a sparse autoencoder (SAE) to cluster training data, allowing for the selection of instances that the model finds challenging yet informative. By introducing a verifier-coupled coverage objective, the method ensures that selected instances enhance learning while remaining interpretable.
The optimization process uses greedy log-determinant maximization to efficiently identify the most beneficial training examples.
