Cognitive Fatigue in Autoregressive Transformers: Formalization and Measurement

ICML 2026poster

Autoregressive language models frequently degrade during long-horizon generation, producing repetitive text, losing instruction adherence, and exhibiting unstable entropy. Despite the prevalence of these failures, practitioners lack online diagnostics to detect them in real time as they occur. We fo…

SConE: Simplified Cone Embeddings with Symbolic Operators for Complex Logical Queries

ACL 2023findings

Geometric representation of query embeddings (using points, particles, rectangles and cones) can effectively achieve the task of answering complex logical queries expressed in first-order logic (FOL) form over knowledge graphs, allowing intuitive encodings. However, current geometric-based methods d…

LexiClean: An annotation tool for rapid multi-task lexical normalisation

EMNLP 2021system demonstrations

NLP systems are often challenged by difficulties arising from noisy, non-standard, and domain specific corpora. The task of lexical normalisation aims to standardise such corpora, but currently lacks suitable tools to acquire high-quality annotated data to support deep learning based approaches. In…
