One-Way Matching of Datasets with Low Rank Signals

no code implementations29 Apr 2022 Shuxiao Chen, Sizun Jiang, Zongming Ma, Garry P. Nolan, Bokai Zhu

We study one-way matching of a pair of datasets with low rank signals.

Learning Torque Control for Quadrupedal Locomotion

no code implementations10 Mar 2022 Shuxiao Chen, Bike Zhang, Mark W. Mueller, Akshara Rai, Koushil Sreenath

Reinforcement learning (RL) has become a promising approach to developing controllers for quadrupedal robots.

Autonomous Navigation of Underactuated Bipedal Robots in Height-Constrained Environments

no code implementations13 Sep 2021 Zhongyu Li, Jun Zeng, Shuxiao Chen, Koushil Sreenath

This demonstrates reliable autonomy to drive the robot to safely avoid obstacles while walking to the goal location in various kinds of height-constrained cluttered environments.

Real-time Geo-localization Using Satellite Imagery and Topography for Unmanned Aerial Vehicles

no code implementations7 Aug 2021 Shuxiao Chen, Xiangyu Wu, Mark W. Mueller, Koushil Sreenath

The capabilities of autonomous flight with unmanned aerial vehicles (UAVs) have significantly increased in recent times.

Weighted Training for Cross-Task Learning

1 code implementation ICLR 2022 Shuxiao Chen, Koby Crammer, Hangfeng He, Dan Roth, Weijie J. Su

In this paper, we introduce Target-Aware Weighted Training (TAWT), a weighted training algorithm for cross-task learning based on minimizing a representation-based task distance between the source and target tasks.

Estimating and Improving Dynamic Treatment Regimes With a Time-Varying Instrumental Variable

no code implementations15 Apr 2021 Shuxiao Chen, Bo Zhang

Estimating dynamic treatment regimes (DTRs) from retrospective observational data is challenging as some degree of unmeasured confounding is often expected.

A Theorem of the Alternative for Personalized Federated Learning

no code implementations2 Mar 2021 Shuxiao Chen, Qinqing Zheng, Qi Long, Weijie J. Su

A widely recognized difficulty in federated learning arises from the statistical heterogeneity among clients: local datasets often come from different but not entirely unrelated distributions, and personalization is, therefore, necessary to achieve optimal results from each individual's perspective.

Personalized Federated Learning

Federated $f$-Differential Privacy

1 code implementation22 Feb 2021 Qinqing Zheng, Shuxiao Chen, Qi Long, Weijie J. Su

Federated learning (FL) is a training paradigm where the clients collaboratively learn models by repeatedly sharing information without compromising much on the privacy of their local sensitive data.

Global and Individualized Community Detection in Inhomogeneous Multilayer Networks

no code implementations2 Dec 2020 Shuxiao Chen, Sifan Liu, Zongming Ma

Focusing on the symmetric two block case, we establish minimax rates for both global estimation of the common structure and individualized estimation of layer-wise community structures.

Label-Aware Neural Tangent Kernel: Toward Better Generalization and Local Elasticity

1 code implementation NeurIPS 2020 Shuxiao Chen, Hangfeng He, Weijie J. Su

As a popular approach to modeling the dynamics of training overparametrized neural networks (NNs), the neural tangent kernels (NTK) are known to fall behind real-world NNs in generalization ability.

A Group-Theoretic Framework for Data Augmentation

1 code implementation NeurIPS 2020 Shuxiao Chen, Edgar Dobriban, Jane H Lee

Data augmentation is a widely used trick when training deep neural networks: in addition to the original data, properly transformed data are also added to the training set.

Valid Inference Corrected for Outlier Removal

1 code implementation29 Nov 2017 Shuxiao Chen, Jacob Bien

Ordinary least square (OLS) estimation of a linear regression model is well-known to be highly sensitive to outliers.
