EMC$^2$: Efficient MCMC Negative Sampling for Contrastive Learning with Global Convergence

ICML 2024poster

A key challenge in contrastive learning is to generate negative samples from a large sample set to contrast with positive samples, for learning better encoding of the data. These negative samples often follow a softmax distribution which are dynamically updated during the training process. However,…

HyTrel: Hypergraph-enhanced Tabular Data Representation Learning

NeurIPS 2023spotlight

Language models pretrained on large collections of tabular data have demonstrated their effectiveness in several downstream tasks. However, many of these models do not take into account the row/column permutation invariances, hierarchical structure, etc. that exist in tabular data. To alleviate thes…
