Safety through Permissibility: Shield Construction for Fast and Safe Reinforcement Learning
Alexander Politowicz, Sahisnu Mazumder, Bing Liu
Designing Reinforcement Learning (RL) solutions for real-life problems remains a significant challenge. A major area of concern is safety. "Shielding" is a popular technique to enf…
Semantic Novelty Detection and Characterization in Factual Text Involving Named Entities
Nianzu Ma, Sahisnu Mazumder, Alexander Politowicz +3
Much of the existing work on text novelty detection has been studied at the topic level, i.e., identifying whether the topic of a document or a sentence is novel or not. Little wor…
Calibrated bootstrap for uncertainty quantification in regression models
Glenn Palmer, Siqi Du, Alexander Politowicz +7
Obtaining accurate estimates of machine learning model uncertainties on newly predicted data is essential for understanding the accuracy of the model and whether its predictions ca…
Assessing Graph-based Deep Learning Models for Predicting Flash Point
Xiaoyu Sun, Nathaniel J. Krakauer, Alexander Politowicz +8
Flash points of organic molecules play an important role in preventing flammability hazards and large databases of measured values exist, although millions of compounds remain unme…
