Anomaly Detection with Test Time Augmentation and Consistency Evaluation

no code implementations6 Jun 2022 Haowei He, Jiaye Teng, Yang Yuan

Deep neural networks are known to be vulnerable to unseen data: they may wrongly assign high confidence stcores to out-distribuion samples.

EVBattery: A Large-Scale Electric Vehicle Dataset for Battery Health and Capacity Estimation

no code implementations28 Jan 2022 Haowei He, Jingzhao Zhang, Yanan Wang, Benben Jiang, Shaobo Huang, Chen Wang, Yang Zhang, Gengang Xiong, Xuebing Han, Dongxu Guo, Guannan He, Minggao Ouyang

In addition to demonstrating how existing deep learning algorithms can be applied to this task, we further develop an algorithm that exploits the data structure of battery systems.

Can Pretext-Based Self-Supervised Learning Be Boosted by Downstream Data? A Theoretical Analysis

no code implementations5 Mar 2021 Jiaye Teng, Weiran Huang, Haowei He

Pretext-based self-supervised learning learns the semantic representation via a handcrafted pretext task over unlabeled data and then uses the learned representation for downstream tasks, which effectively reduces the sample complexity of downstream tasks under Conditional Independence (CI) condition.

Asymmetric Valleys: Beyond Sharp and Flat Local Minima

1 code implementation NeurIPS 2019 Haowei He, Gao Huang, Yang Yuan

Specifically, at a local minimum there exist many asymmetric directions such that the loss increases abruptly along one side, and slowly along the opposite side--we formally define such minima as asymmetric valleys.
