arXiv:2602.22600v2 Announce Type: replace-cross Abstract: Training selects for behavior, not circuitry: many weight configurations can implement the same function. Studying any single trained neural network thus risks describing accidents of one training run rather than the computation itself. This work shifts focus from what transformers happen to do to what they must do by extracting algorithmic cores, compact subspaces that are necessary and sufficient for a task and that recur across independently trained models. Here, Algorithmic Core Extraction (ACE) is introduced to isolate these subspa
The rapid advancement and widespread deployment of transformer models have led to a critical need to understand their underlying computational mechanisms beyond just their observed behavior.
Understanding invariant algorithmic cores can lead to more robust, interpretable, and efficient AI systems, fundamentally advancing our capability to design and debug complex models.
The focus in AI research shifts from mere functional observation to extracting and understanding the inherent computational logic within neural networks, allowing for more principle-driven development.
