Text Style Transfer: Leveraging a Style Classifier on Entangled Latent Representations

no code implementations ACL (RepL4NLP) 2021 Xiaoyan Li, Sun Sun, Yunli Wang

We propose a novel text style transfer algorithm with entangled latent representation, and introduce a style classifier that can regulate the latent structure and transfer style.

$f$-MICL: Understanding and Generalizing InfoNCE-based Contrastive Learning

no code implementations15 Feb 2024 Yiwei Lu, Guojun Zhang, Sun Sun, Hongyu Guo, YaoLiang Yu

In self-supervised contrastive learning, a widely-adopted objective function is InfoNCE, which uses the heuristic cosine similarity for the representation comparison, and is closely related to maximizing the Kullback-Leibler (KL)-based mutual information.

SoftEdge: Regularizing Graph Classification with Random Soft Edges

no code implementations21 Apr 2022 Hongyu Guo, Sun Sun

Augmented graphs play a vital role in regularizing Graph Neural Networks (GNNs), which leverage information exchange along edges in graphs, in the form of message passing, for learning.

Symmetric Wasserstein Autoencoders

1 code implementation24 Jun 2021 Sun Sun, Hongyu Guo

With the symmetric treatment of the data and the latent representation, the algorithm implicitly preserves the local structure of the data in the latent space.
