Revisiting Sharpness-Aware Minimization: A More Faithful and Effective Implementation

ICLR 2026poster

Sharpness-Aware Minimization (SAM) enhances generalization by minimizing the maximum training loss within a predefined neighborhood around the parameters. However, its practical implementation approximates this as gradient ascent(s) followed by applying the gradient at the ascent point to update the…

Recurrent Temporal Revision Graph Networks

NeurIPS 2023poster

Temporal graphs offer more accurate modeling of many real-world scenarios than static graphs. However, neighbor aggregation, a critical building block of graph networks, for temporal graphs, is currently straightforwardly extended from that of static graphs. It can be computationally expensive when…

Exposure Bias versus Self-Recovery: Are Distortions Really Incremental for Autoregressive Text Generation?

EMNLP 2021main

Exposure bias has been regarded as a central problem for auto-regressive language models (LM). It claims that teacher forcing would cause the test-time generation to be incrementally distorted due to the training-generation discrepancy. Although a lot of algorithms have been proposed to avoid teache…

Lipschitz Generative Adversarial Nets

ICML 2019oral

In this paper we show that generative adversarial networks (GANs) without restriction on the discriminative function space commonly suffer from the problem that the gradient produced by the discriminator is uninformative to guide the generator. By contrast, Wasserstein GAN (WGAN), where the discrimi…

Activation Maximization Generative Adversarial Nets

ICLR 2018poster

Class labels have been empirically shown useful in improving the sample quality of generative adversarial nets (GANs). In this paper, we mathematically study the properties of the current variants of GANs that make use of class label information. With class aware gradient and cross-entropy decomposi…
