Interpretable Traffic Event Analysis with Bayesian Networks

no code implementations10 Oct 2023 Tong Yuan, Jian Yang, Zeyi Wen

With a concrete case study, our framework can derive a Bayesian Network from a dataset based on the causal relationships between weather and traffic events across the United States.

Fast Parallel Bayesian Network Structure Learning

1 code implementation8 Dec 2022 Jiantong Jiang, Zeyi Wen, Ajmal Mian

The mainstream BN structure learning methods require performing a large number of conditional independence (CI) tests.

Fast Parallel Exact Inference on Bayesian Networks: Poster

1 code implementation8 Dec 2022 Jiantong Jiang, Zeyi Wen, Atif Mansoor, Ajmal Mian

Bayesian networks (BNs) are attractive, because they are graphical and interpretable machine learning models.

Efficient Second-Order Optimization for Deep Learning with Kernel Machines

no code implementations29 Sep 2021 Yawen Chen, Zeyi Wen, Yile Chen, Jian Chen, Jin Huang

However, the recomputation of the Hessian matrix in the second-order optimization posts much extra computation and memory burden in the training.

Entity Extraction with Knowledge from Web Scale Corpora

no code implementations21 Nov 2019 Zeyi Wen, Zeyu Huang, Rui Zhang

Entity extraction is an important task in text mining and natural language processing.

Privacy-Preserving Gradient Boosting Decision Trees

2 code implementations11 Nov 2019 Qinbin Li, Zhaomin Wu, Zeyi Wen, Bingsheng He

Specifically, by investigating the property of gradient and the contribution of each tree in GBDTs, we propose to adaptively control the gradients of training data for each iteration and leaf node clipping in order to tighten the sensitivity bounds.
