Coherence-Aware Distributional Evaluation of Open-Ended Text Generation

Jinnuo Liu, Junhao Zhu, Weifeng Jiang et al. · 2026

Existing open-ended generation metrics measure likelihood, lexical diversity, or distributional similarity in generic representation space, yet can miss fundamental dimensions of quality. A prominent blind spot is global coherence: a generated passage may be locally fluent while remaining globally contradictory, causal …

Early Learning Shapes Later Directions Of Representation Change In Continual Learning

Yuantao Deng, Jinnuo Liu, Kaizhen Tan et al. · 2026

Representations continually change as a network learns new tasks. We ask whether early representational changes naturally form a geometric structure that continues to shape later learning. We identify a low-dimensional subspace of early representation drift, which we call a scaffold, and test whether it is reused acros …
