Convergence and Generalization of Wide Neural Networks with Large Bias

no code implementations1 Jan 2023 Hongru Yang, Ziyu Jiang, Ruizhe Zhang, Zhangyang Wang, Yingbin Liang

This work studies training one-hidden-layer overparameterized ReLU networks via gradient descent in the neural tangent kernel (NTK) regime, where the networks' biases are initialized to some constant rather than zero.

M$^3$ViT: Mixture-of-Experts Vision Transformer for Efficient Multi-task Learning with Model-Accelerator Co-design

1 code implementation26 Oct 2022 Hanxue Liang, Zhiwen Fan, Rishov Sarkar, Ziyu Jiang, Tianlong Chen, Kai Zou, Yu Cheng, Cong Hao, Zhangyang Wang

However, when deploying MTL onto those real-world systems that are often resource-constrained or latency-sensitive, two prominent challenges arise: (i) during training, simultaneously optimizing all tasks is often difficult due to gradient conflicts across tasks; (ii) at inference, current MTL regimes have to activate nearly the entire model even to just execute a single task.

Self-Damaging Contrastive Learning

1 code implementation6 Jun 2021 Ziyu Jiang, Tianlong Chen, Bobak Mortazavi, Zhangyang Wang

Hence, the key innovation in SDCLR is to create a dynamic self-competitor model to contrast with the target model, which is a pruned version of the latter.

Robust Pre-Training by Adversarial Contrastive Learning

1 code implementation NeurIPS 2020 Ziyu Jiang, Tianlong Chen, Ting Chen, Zhangyang Wang

Recent work has shown that, when integrated with adversarial training, self-supervised pre-training can lead to state-of-the-art robustness In this work, we improve robustness-aware self-supervised pre-training by learning representations that are consistent under both data augmentations and adversarial perturbations.

Peek-a-Boo: Occlusion Reasoning in Indoor Scenes With Plane Representations

no code implementations CVPR 2020 Ziyu Jiang, Buyu Liu, Samuel Schulter, Zhangyang Wang, Manmohan Chandraker

It consists of a two-branch category-specific module that aims to predict layout and objects of the scene separately so that different types of planes can be handled better.
