StructComp: Substituting propagation with Structural Compression in Training Graph Contrastive Learning

1 code implementation8 Dec 2023 Shengzhong Zhang, Wenjie Yang, Xinyuan Cao, Hongwei Zhang, Zengfeng Huang

This allows the encoder not to perform any message passing during the training stage, and significantly reduces the number of sample pairs in the contrastive loss.

Towards Understanding Neural Collapse: The Effects of Batch Normalization and Weight Decay

no code implementations9 Sep 2023 Leyan Pan, Xinyuan Cao

Neural Collapse (NC) is a geometric structure recently observed in the final layer of neural network classifiers.

Graph-Level Embedding for Time-Evolving Graphs

no code implementations1 Jun 2023 Lili Wang, Chenghan Huang, Weicheng Ma, Xinyuan Cao, Soroush Vosoughi

We evaluate our proposed model on five publicly available datasets for the task of temporal graph similarity ranking, and our model outperforms baseline methods.

Learning-Augmented B-Trees

no code implementations16 Nov 2022 Xinyuan Cao, Jingbang Chen, Li Chen, Chris Lambert, Richard Peng, Daniel Sleator

We study learning-augmented binary search trees (BSTs) and B-Trees via Treaps with composite priorities.

Provable Lifelong Learning of Representations

no code implementations27 Oct 2021 Xinyuan Cao, Weiyang Liu, Santosh S. Vempala

We prove that for any desired accuracy on all tasks, the dimension of the representation remains close to that of the underlying representation.
