Rethinking "Batch" in BatchNorm

1 code implementation17 May 2021 Yuxin Wu, Justin Johnson

BatchNorm is a critical building block in modern convolutional neural networks.

Bayesian Relational Memory for Semantic Visual Navigation

1 code implementation ICCV 2019 Yi Wu, Yuxin Wu, Aviv Tamar, Stuart Russell, Georgia Gkioxari, Yuandong Tian

We introduce a new memory architecture, Bayesian Relational Memory (BRM), to improve the generalization ability for semantic visual navigation agents in unseen environments, where an agent is given a semantic target to navigate towards.

Natural Environment Benchmarks for Reinforcement Learning

1 code implementation14 Nov 2018 Amy Zhang, Yuxin Wu, Joelle Pineau

While current benchmark reinforcement learning (RL) tasks have been useful to drive progress in the field, they are in many ways poor substitutes for learning with real-world data.

Building Generalizable Agents with a Realistic and Rich 3D Environment

5 code implementations ICLR 2018 Yi Wu, Yuxin Wu, Georgia Gkioxari, Yuandong Tian

To generalize to unseen environments, an agent needs to be robust to low-level variations (e. g. color, texture, object changes), and also high-level variations (e. g. layout changes of the environment).

12 code implementations20 Jun 2016 Shuchang Zhou, Yuxin Wu, Zekun Ni, Xinyu Zhou, He Wen, Yuheng Zou

We propose DoReFa-Net, a method to train convolutional neural networks that have low bitwidth weights and activations using low bitwidth parameter gradients.


Exploiting Local Structures with the Kronecker Layer in Convolutional Networks

no code implementations31 Dec 2015 Shuchang Zhou, Jia-Nan Wu, Yuxin Wu, Xinyu Zhou

Multilinear Map Layer: Prediction Regularization by Structural Constraint

no code implementations30 Jul 2015 Shuchang Zhou, Yuxin Wu

In this paper we propose and study a technique to impose structural constraints on the output of a neural network, which can reduce amount of computation and number of parameters besides improving prediction accuracy when the output is known to approximately conform to the low-rankness prior.
