On Efficient Online Imitation Learning via Classification
Yichen Li, Chicheng Zhang
Imitation learning (IL) is a general learning paradigm for tackling sequential decision-making problems. Interactive imitation learning, where learners can interactively query for…
Margin-distancing for safe model explanation
Tom Yan, Chicheng Zhang
The growing use of machine learning models in consequential settings has highlighted an important and seemingly irreconcilable tension between transparency and vulnerability to gam…
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…
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…
Multitask Bandit Learning Through Heterogeneous Feedback Aggregation
Zhi Wang, Chicheng Zhang, Manish Kumar Singh +2
In many real-world applications, multiple agents seek to learn how to perform highly related yet slightly different tasks in an online bandit learning protocol. We formulate this p…
