Learning Deep Modality-Shared Self-Expressiveness for Image Clustering with Textual Information
Xianghan Meng, Wei He, Zhiyuan Huang +1
Leveraging textual information for image clustering has emerged as a promising direction, largely owing to the powerful representations learned by Vision-Language Models (VLMs). Ex…
Mixture-of-Top-k Attention: Efficient Attention via Scalable Fast Weights
Qishuai Wen, Zhiyuan Huang, Xianghan Meng +2
The vanilla self-attention mechanism in Transformers can be viewed as a two-layer fast-weight MLP, whose weights are dynamically induced by inputs and whose hidden dimension is equ…
Jointly Learning Structured Representations and Stabilized Affinity for Human Motion Segmentation
Xianghan Meng, Zhiyuan Huang, Zhengyu Tong +1
Human Motion Segmentation (HMS), which aims to partition a video into non-overlapping segments corresponding to different human motions, has recently attracted increasing research…
Multi-Modal Representation Learning via Semi-Supervised Rate Reduction for Generalized Category Discovery
Wei He, Xianghan Meng, Zhiyuan Huang +3
Generalized Category Discovery (GCD) aims to identify both known and unknown categories, with only partial labels given for the known categories, posing a challenging open-set reco…
Temporal Rate Reduction Clustering for Human Motion Segmentation
Xianghan Meng, Zhengyu Tong, Zhiyuan Huang +1
Human Motion Segmentation (HMS), which aims to partition videos into non-overlapping human motions, has attracted increasing research attention recently. Existing approaches for HM…
Exploring a Principled Framework for Deep Subspace Clustering
Xianghan Meng, Zhiyuan Huang, Wei He +3
Subspace clustering is a classical unsupervised learning task, built on a basic assumption that high-dimensional data can be approximated by a union of subspaces (UoS). Nevertheles…
