Spectral Classification Stability Engine: From Idea to Results
(Antonio V. Franco) It all started with a pun. Not just any pun (but one of those that makes more sense the longer you think about it). The Stable-RAG method, proposed by Zhang et al. (2026), uses spectral clustering on the hidden states of language models to identify distinct reasoning modes. Astronomy, in turn, studies spectral features of celestial objects (emission lines, absorption lines, the continuum) as the primary diagnostic tool for classification. Two meanings of the same word, “spectral,” belonging to seemingly distant domains. ...
