HyperSMOTE: A Hypergraph-based Oversampling Approach for Imbalanced Node Classifications

ICASSP 2025accepted

Hypergraphs are increasingly utilized in both unimodal and multimodal data scenarios due to their superior ability to model and extract higher-order relationships among nodes, compared to traditional graphs. However, current hypergraph models are encountering challenges related to imbalanced data, a…

SAMA: Towards Multi-Turn Referential Grounded Video Chat with Large Language Models

NeurIPS 2025poster

Achieving fine-grained spatio-temporal understanding in videos remains a major challenge for current Video Large Multimodal Models (Video LMMs). Addressing this challenge requires mastering two core capabilities: video referring understanding, which captures the semantics of video regions, and video…

Exploiting Spatial-Temporal Data for Sleep Stage Classification via Hypergraph Learning

ICASSP 2024accepted

Sleep stage classification is crucial for detecting patients’ health conditions. Existing models, which mainly use Convolutional Neural Networks (CNN) for modelling Euclidean data and Graph Convolution Networks (GNN) for modelling non-Euclidean data, are unable to consider the heterogeneity and inte…

UnSeg: One Universal Unlearnable Example Generator is Enough against All Image Segmentation

NeurIPS 2024poster

Image segmentation is a crucial vision task that groups pixels within an image into semantically meaningful segments, which is pivotal in obtaining a fine-grained understanding of real-world scenes. However, an increasing privacy concern exists regarding training large-scale image segmentation model…
