New 'interior interpretability' method probes Transformer models

Researchers have introduced a new concept called "interior interpretability" to better understand the internal workings of Transformer models. This approach uses attention rollout, viewing it as an operator that mediates information propagation between feature tokens. By applying contraction theory, they found that in Transformers trained for metabolomic age prediction, this propagation becomes more pronounced with increased model depth. While attention rollout offers insights into attention-mediated propagation, it is not presented as a definitive causal explanation or a complete attribution method. AI

IMPACT Offers a novel method for analyzing internal model behavior, potentially improving understanding and debugging of complex Transformer architectures.

    Interior interpretability with attention rollout: contraction and propagation profiles in Transformers

    arXiv:2607.22367v1 Announce Type: new Abstract: Feature-attribution methods assign scores relating input variables to a model's output, but do not by themselves characterize how explicitly defined interaction operators compose across its intermediate layers. We introduce \emph{in…
