From Input to Output: A Flexible Agent for Dual-End Interpretation of Sparse Autoencoder Features
Functional interpretation is introduced, which characterizes an SAE feature as a mapping from its activating input semantics to its output effects under intervention, and Dual-End Agentic Feature Interpretation (DAFI) is presented, an agent that actively gathers evidence and refines input-side, output-side, and functio...
