Training Bayesian Neural Networks with Sparse Subspace Variational Inference

1 code implementation16 Feb 2024 Junbo Li, Zichen Miao, Qiang Qiu, Ruqi Zhang

Bayesian neural networks (BNNs) offer uncertainty quantification but come with the downside of substantially increased training and inference costs.

Hedonic Prices and Quality Adjusted Price Indices Powered by AI

no code implementations28 Apr 2023 Patrick Bajari, Zhihao Cen, Victor Chernozhukov, Manoj Manukonda, Suhas Vijaykunar, Jin Wang, Ramon Huerta, Junbo Li, Ling Leng, George Monokroussos, Shan Wan

To accomplish this, we generate abstract product attributes, or ``features,'' from text descriptions and images using deep neural networks, and then use these attributes to estimate the hedonic price function.

Benchmarking Robustness in Neural Radiance Fields

no code implementations10 Jan 2023 Chen Wang, Angtian Wang, Junbo Li, Alan Yuille, Cihang Xie

We find that NeRF-based models are significantly degraded in the presence of corruption, and are more sensitive to a different set of corruptions than image recognition models.

Exponential Family Model-Based Reinforcement Learning via Score Matching

1 code implementation28 Dec 2021 Gene Li, Junbo Li, Anmol Kabra, Nathan Srebro, Zhaoran Wang, Zhuoran Yang

We propose an optimistic model-based algorithm, dubbed SMRL, for finite-horizon episodic reinforcement learning (RL) when the transition model is specified by exponential family distributions with $d$ parameters and the reward is bounded and known.

In this work, we report the set-up and results of the Liver Tumor Segmentation Benchmark (LiTS), which was organized in conjunction with the IEEE International Symposium on Biomedical Imaging (ISBI) 2017 and the International Conferences on Medical Image Computing and Computer-Assisted Intervention (MICCAI) 2017 and 2018.
