See the Emotion: A Facial Emoji Proxy Modeling for EEG Emotion Recognition
Jingjing Hu, Guo Dan, Haofan Cheng +4
Despite the high accuracy of EEG-based emotion recognition, existing models remain opaque "black boxes", lacking semantic grounding between abstract neural features and human-inter…
FreqPhys: Repurposing Implicit Physiological Frequency Prior for Robust Remote Photoplethysmography
Wei Qian, Dan Guo, Jinxing Zhou +3
Remote photoplethysmography (rPPG) enables contactless physiological monitoring by capturing subtle skin-color variations from facial videos. However, most existing methods predomi…
Face-Guided Sentiment Boundary Enhancement for Weakly-Supervised Temporal Sentiment Localization
Cailing Han, Zhangbin Li, Jinxing Zhou +5
Point-level weakly-supervised temporal sentiment localization (P-WTSL) aims to detect sentiment-relevant segments in untrimmed multimodal videos using timestamp sentiment annotatio…
Learning Spatial Decay for Vision Transformers
Yuxin Mao, Zhen Qin, Jinxing Zhou +4
Vision Transformers (ViTs) have revolutionized computer vision, yet their self-attention mechanism lacks explicit spatial inductive biases, leading to suboptimal performance on spa…
A Closer Look at Knowledge Distillation in Spiking Neural Network Training
Xu Liu, Na Xia, Jinxing Zhou +2
Spiking Neural Networks (SNNs) become popular due to excellent energy efficiency, yet facing challenges for effective model training. Recent works improve this by introducing knowl…
SimToken: A Simple Baseline for Referring Audio-Visual Segmentation
Dian Jin, Yanghao Zhou, Jinxing Zhou +3
Referring Audio-Visual Segmentation (Ref-AVS) aims to segment specific objects in videos based on natural language expressions involving audio, vision, and text information. This t…
