Predicting Out-of-Distribution Error with Confidence Optimal Transport

no code implementations10 Feb 2023 Yuzhe Lu, Zhenlin Wang, Runtian Zhai, Soheil Kolouri, Joseph Campbell, Katia Sycara

Out-of-distribution (OOD) data poses serious challenges in deployed machine learning models as even subtle changes could incur significant performance drops.

Best Arm Identification with Safety Constraints

1 code implementation23 Nov 2021 Zhenlin Wang, Andrew Wagenmaker, Kevin Jamieson

The best arm identification problem in the multi-armed bandit setting is an excellent model of many real-world decision-making problems, yet it fails to capture the fact that in the real-world, safety constraints often must be met while learning.

Max-Min Grouped Bandits

no code implementations17 Nov 2021 Zhenlin Wang, Jonathan Scarlett

In this paper, we introduce a multi-armed bandit problem termed max-min grouped bandits, in which the arms are arranged in possibly-overlapping groups, and the goal is to find the group whose worst arm has the highest mean reward.

Exploring General Intelligence of Program Analysis for Multiple Tasks

no code implementations29 Sep 2021 Yixin Guo, Pengcheng Li, Yingwei Luo, Xiaolin Wang, Zhenlin Wang

To this end, we explore a generic program embedding approach that aim at solving multiple program analysis tasks.

GRAPHSPY: Fused Program Semantic-Level Embedding via Graph Neural Networks for Dead Store Detection

no code implementations18 Nov 2020 Yixin Guo, Pengcheng Li, Yingwei Luo, Xiaolin Wang, Zhenlin Wang

To this end, we propose a learning-aided approach to identify unnecessary memory operations intelligently with low overhead.

System inference for the spatio-temporal evolution of infectious diseases: Michigan in the time of COVID-19

no code implementations2 Jul 2020 Zhenlin Wang, Xiaoxuan Zhang, Gregory Teichert, Mariana Carrasco-Teja, Krishna Garikipati

We extend the classical SIR model of infectious disease spread to account for time dependence in the parameters, which also include diffusivities.
