Equivariant Contrastive Learning

open access: yesCoRR, 2021
In state-of-the-art self-supervised learning (SSL) pre-training produces semantically good representations by encouraging them to be invariant under meaningful transformations prescribed from human knowledge. In fact, the property of invariance is a trivial instance of a broader class called equivariance, which can be intuitively understood as the ...

An Asymmetric Contrastive Loss for Handling Imbalanced Datasets

open access: yesEntropy, 2022
Contrastive learning is a representation learning method performed by contrasting a sample to other similar samples so that they are brought closely together, forming clusters in the feature space.

Grouped Contrastive Learning of Self-Supervised Sentence Representation

open access: yesApplied Sciences, 2023
This paper proposes a method called Grouped Contrastive Learning of self-supervised Sentence Representation (GCLSR), which can learn an effective and meaningful representation of sentences. Previous works maximize the similarity between two vectors to be

Decoupled Contrastive Learning

open access: yes, 2022
Contrastive learning (CL) is one of the most successful paradigms for self-supervised learning (SSL). In a principled way, it considers two augmented "views" of the same image as positive to be pulled closer, and all other images as negative to be pushed further apart.

A Contrastive Rule for Meta-Learning

open access: yesAdvances in Neural Information Processing Systems 35, 2022
Meta-learning algorithms leverage regularities that are present on a set of tasks to speed up and improve the performance of a subsidiary learning process. Recent work on deep neural networks has shown that prior gradient-based learning of meta-parameters can greatly improve the efficiency of subsequent learning.

Efficient Learning for Undirected Topic Models [PDF]

open access: yes, 2015
Replicated Softmax model, a well-known undirected topic model, is powerful in extracting semantic representations of documents. Traditional learning strategies such as Contrastive Divergence are very inefficient.
