SIM-ECG: A Signal Importance Mask-driven ECGClassification System
Dharma KC, Chicheng Zhang, Chris Gniady +2
Heart disease is the number one killer, and ECGs can assist in the early diagnosis and prevention of deadly outcomes. Accurate ECG interpretation is critical in detecting heart dis…
Improving the trustworthiness of image classification models by utilizing bounding-box annotations
Dharma KC, Chicheng Zhang
We study utilizing auxiliary information in training data to improve the trustworthiness of machine learning models. Specifically, in the context of image classification, we propos…
Provably Efficient Multi-Task Reinforcement Learning with Model Transfer
Chicheng Zhang, Zhi Wang
We study multi-task reinforcement learning (RL) in tabular episodic Markov decision processes (MDPs). We formulate a heterogeneous multi-player RL problem, in which a group of play…
Improved Algorithms for Efficient Active Learning Halfspaces with Massart and Tsybakov noise
Chicheng Zhang, Yinan Li
We give a computationally-efficient PAC active learning algorithm for -dimensional homogeneous halfspaces that can tolerate Massart noise (Massart and Nédélec, 2006) and Tsybako…
