RSIBench-Data Benchmark: AI Agents Can Improve Training Data but Struggle to Stop in Time
RSIBench-Data is a newly proposed benchmark designed to evaluate whether large language model agents can perform 'data-centric' recursive self-improvement (RSI) research like human researchers. By fixing the model's training setup, the benchmark lets coding agents iteratively optimize the training data of another independent LLM. Experiments show that agents are capable of improving data strategies but face a significant deficiency in 'stopping in time' at the optimal point.
Confirmed
- The benchmark decouples the research process from system implementation, allowing agents to focus on tasks such as diagnosing data issues, generating new data strategies, and evaluating results.
- Experiments are conducted on the Tinker platform with fixed training settings.
- Core experimental data shows that out of 24 experimental settings, 14 improved over the first attempt through feedback optimization.
- Agents lack the ability to stop after reaching peak performance: in 23 experiments where they continued searching after the peak, 18 resulted in degradation and 5 remained unchanged.
Why it matters
This is the first benchmark to evaluate agents' recursive self-improvement capabilities. It not only confirms the great potential of AI agents in automated scientific research and training data optimization but also exposes a critical weakness in current models' decision boundary control (i.e., 'stopping in time'), pointing the way for developing more robust automated research agents in the future.
