The Double Regularization Method for Capacity Constrained Optimal Transport
Tianhao Wu, Qihao Cheng, Zihao Wang +4
Capacity constrained optimal transport is a variant of optimal transport, which adds extra constraints on the set of feasible couplings in the original optimal transport problem to…
MICO: A Multi-alternative Contrastive Learning Framework for Commonsense Knowledge Representation
Ying Su, Zihao Wang, Tianqing Fang +3
Commonsense reasoning tasks such as commonsense knowledge graph completion and commonsense question answering require powerful representation learning. In this paper, we propose to…
Unsupervised Sentence Textual Similarity with Compositional Phrase Semantics
Zihao Wang, Jiaheng Dou, Yong Zhang
Measuring Sentence Textual Similarity (STS) is a classic task that can be applied to many downstream NLP applications such as text generation and retrieval. In this paper, we focus…
Fast Sinkhorn II: Collinear Triangular Matrix and Linear Time Accurate Computation of Optimal Transport
Qichen Liao, Zihao Wang, Jing Chen +3
In our previous work [arXiv:2202.10042], the complexity of Sinkhorn iteration is reduced from to the optimal by leveraging the special structure of the kernel matri…
Posterior Collapse of a Linear Latent Variable Model
Zihao Wang, Liu Ziyin
This work identifies the existence and cause of a type of posterior collapse that frequently occurs in the Bayesian deep learning practice. For a general linear latent variable mod…
Query2Particles: Knowledge Graph Reasoning with Particle Embeddings
Jiaxin Bai, Zihao Wang, Hongming Zhang +1
Answering complex logical queries on incomplete knowledge graphs (KGs) with missing edges is a fundamental and important task for knowledge graph reasoning. The query embedding met…
