Representation Trajectories Matters: Complementary Evidence for OOD Detection and Image Classification

This work asks whether the resulting computation path contains evidence that the final representation discards, and whether that evidence improves OOD detection and image classification on clean and shifted data, and whether that evidence improves OOD detection and image classification on clean and shifted data.

Reasoning Errors Have a Region and a Direction in the Residual-Stream Trajectory of LLMs

It is suggested that reasoning validity is better read from state-conditioned motion than from either static states or decontextualized trajectories alone, andlations show that motion, region, and direction provide complementary signals.

Level, Sharpness, and Corpus: Why Zero-Shot OOD Detector Rankings Do Not Transfer

The Complementary Evidence Guard (CEG), a detector-agnostic wrapper that preserves complementary evidence through a non-compensatory fusion of the base detector, level, and sharpness using only empirical in-distribution percentiles is introduced.
