Why the pseudo label based semi-supervised learning algorithm is effective?

no code implementations18 Nov 2022 Zeping Min, Qian Ge, Cheng Tai

The core idea of the pseudo label based semi-supervised learning algorithm is to use the model trained on the labeled data to generate pseudo labels on the unlabeled data, and then train a model to fit the previously generated pseudo labels.

Exploring and Enhancing the Transferability of Adversarial Examples

no code implementations ICLR 2019 Lei Wu, Zhanxing Zhu, Cheng Tai

State-of-the-art deep neural networks are vulnerable to adversarial examples, formed by applying small but malicious perturbations to the original inputs.

Stochastic Modified Equations and Dynamics of Stochastic Gradient Algorithms I: Mathematical Foundations

no code implementations5 Nov 2018 Qianxiao Li, Cheng Tai, Weinan E

We develop the mathematical foundations of the stochastic modified equations (SME) framework for analyzing the dynamics of stochastic gradient algorithms, where the latter is approximated by a class of stochastic differential equations with small noise parameters.
