Can AI Really Judge Good Design? Findings from the Design Crit Study

Contra Labs' Design Crit dataset reveals that while AI can generate images, current AI judges barely outperform random guessing in assessing design quality, but a small fine‑tuned model can close nearly half the gap to human agreement by learning from expert‑rated criteria.

Enhancing Uncertainty Modeling with Semantic Graph for Hallucination Detection

The authors present a semantic‑graph‑enhanced uncertainty modeling framework that captures token, sentence, and paragraph dependencies, propagates uncertainty through entity relations and contradiction probabilities, and achieves roughly a 20 % gain in paragraph‑level hallucination detection on WikiBio and NoteSum compared with existing uncertainty‑based baselines.
