VADER: Adaptive Debiasing for Hallucination Mitigation in Video Large Language Models
Dong Xing, Jiaxin Chen, Hang Yang +3
Large vision-language models (LVLMs) have demonstrated strong performance in open-ended video understanding, yet they remain prone to fluent responses unsupported by video evidence…
Disentangling Acoustic Cues in Alzheimer's Pathology and Perception: The Roles of Language and Gender
Liu He, Yuanchao Li, Yin-Long Liu +5
Acoustic biomarkers show promise for detecting Alzheimer's Disease (AD), yet whether the cues driving diagnostic AI align with those salient to human listeners is underexplored acr…
CoSTA: Cognitive-State-Conditioned TTS Data Augmentation Using ASR Transcripts for Alzheimer's Disease Detection
Yin-Long Liu, Yuanchao Li, Yiming Wang +8
Speech-based Alzheimer's Disease (AD) detection is constrained by scarce pathological speech data. To address this, we propose CoSTA, a Text-to-Speech (TTS)-based data augmentation…
Decoding Speaker-Normalized Pitch from EEG for Mandarin Perception
Jiaxin Chen, Yiming Wang, Ziyu Zhang +6
The same speech content produced by different speakers exhibits significant differences in pitch contour, yet listeners' semantic perception remains unaffected. This phenomenon may…
