Conformal Counterfactual Inference under Hidden Confounding

no code implementations20 May 2024 Zonghao Chen, Ruocheng Guo, Jean-François Ton, Yang Liu

Personalized decision making requires the knowledge of potential outcomes under different treatments, and confidence intervals about the potential outcomes further enrich this decision-making process and improve its reliability in high-stakes scenarios.

Tractable Function-Space Variational Inference in Bayesian Neural Networks

1 code implementation28 Dec 2023 Tim G. J. Rudner, Zonghao Chen, Yee Whye Teh, Yarin Gal

Recognizing that the primary object of interest in most settings is the distribution over functions induced by the posterior distribution over neural network parameters, we frame Bayesian inference in neural networks explicitly as inferring a posterior distribution over functions and propose a scalable function-space variational inference method that allows incorporating prior information and results in reliable predictive uncertainty estimates.

PanoViT: Vision Transformer for Room Layout Estimation from a Single Panoramic Image

no code implementations23 Dec 2022 Weichao Shen, Yuan Dong, Zonghao Chen, Zhengyi Zhao, Yang Gao, Zhu Liu

In this paper, we propose PanoViT, a panorama vision transformer to estimate the room layout from a single panoramic image.

Efficient Neural Network Training via Forward and Backward Propagation Sparsification

1 code implementation NeurIPS 2021 Xiao Zhou, Weizhong Zhang, Zonghao Chen, Shizhe Diao, Tong Zhang

For the latter step, instead of using the chain rule based gradient estimators as in existing methods, we propose a variance reduced policy gradient estimator, which only requires two forward passes without backward propagation, thus achieving completely sparse training.
