Threshold-aware Learning to Generate Feasible Solutions for Mixed Integer Programs

no code implementations1 Aug 2023 Taehyun Yoon, Jinwon Choi, Hyokun Yun, Sungbin Lim

Our study investigates that a specific range of variable assignment rates (coverage) yields high-quality feasible solutions, where we suggest optimizing the coverage bridges the gap between the learning and MIP objectives.

Evaluating Out-of-Distribution Detectors Through Adversarial Generation of Outliers

1 code implementation20 Aug 2022 Sangwoong Yoon, Jinwon Choi, Yonghyeon LEE, Yung-Kyun Noh, Frank Chongwoo Park

A reliable evaluation method is essential for building a robust out-of-distribution (OOD) detector.

Adversarial Distributions Against Out-of-Distribution Detectors

no code implementations29 Sep 2021 Sangwoong Yoon, Jinwon Choi, Yonghyeon LEE, Yung-Kyun Noh, Frank C. Park

As an outlier may deviate from the training distribution in unexpected ways, an ideal OOD detector should be able to detect all types of outliers.

Out of Distribution (OOD) Detection

A Statistical Manifold Framework for Point Cloud Data

no code implementations29 Sep 2021 Yonghyeon LEE, Seungyeon Kim, Jinwon Choi, Frank C. Park

The only requirement on the part of the user is the choice of a meaningful underlying probability distribution, which is more intuitive and natural to make than what is required in existing ad hoc formulations.
