arXiv:2606.09940v1 Announce Type: new Abstract: Dictionary learning methods like Sparse Autoencoders (SAEs) and crosscoders attempt to explain a model by decomposing its activations into independent features. Interactions between features hence induce errors in the reconstruction. We formalize this intuition via compact proofs and make five contributions. First, we show how, \textit{in principle}, a compact proof of model performance can be constructed using a crosscoder. Second, we show that an error term arising in this proof can naturally be interpreted as a measure of interaction between c
This research is emerging as the field of AI interpretability, particularly for large language models, becomes crucial for understanding and controlling increasingly complex AI systems.
Understanding feature interactions within AI models is vital for improving their reliability, robustness, and safety, impacting critical applications and regulatory oversight.
The formalization of feature interactions provides a more rigorous framework for evaluating and designing more interpretable AI models, moving beyond qualitative assessments.
