Knowing the Answer Isn't Enough: Fixing Reasoning Path Failures in LVLMs

Chaoyang Wang, Yangfan He, Yiyang Zhou +6

We reveal a critical yet underexplored flaw in Large Vision-Language Models (LVLMs): even when these models know the correct answer, they frequently arrive there through incorrect…

Emotion-Aligned Generation in Diffusion Text to Speech Models via Preference-Guided Optimization

Jiacheng Shi, Hongfei Du, Yangfan He +2

Emotional text-to-speech seeks to convey affect while preserving intelligibility and prosody, yet existing methods rely on coarse labels or proxy classifiers and receive only utter…

GLIMPSE: Do Large Vision-Language Models Truly Think With Videos or Just Glimpse at Them?

Yiyang Zhou, Linjie Li, Shi Qiu +10

Existing video benchmarks often resemble image-based benchmarks, with question types like "What actions does the person perform throughout the video?" or "What color is the woman's…
