A Data-driven Region Generation Framework for Spatiotemporal Transportation Service Management

no code implementations5 Jun 2023 Liyue Chen, Jiangyi Fang, Zhe Yu, Yongxin Tong, Shaosheng Cao, Leye Wang

In this paper, we propose RegionGen, a data-driven region generation framework that can specify regions with key characteristics (e. g., good spatial semantic meaning and predictability) by modeling region generation as a multi-objective optimization problem.

Testing Relative Fairness in Human Decisions With Machine Learning

no code implementations21 Dec 2021 Zhe Yu, Xiaoyin Xi

Such relative fairness has the following benefits: (1) it avoids the ambiguous and contradictory definition of "absolute" fair decisions; (2) it reveals the relative preference and bias between different human decisions; (3) if a reference set of decisions is provided, relative fairness of other decision sets against this reference set can reflect whether those decision sets are fair by the standard of that reference set.

FairBalance: How to Achieve Equalized Odds With Data Pre-processing

1 code implementation17 Jul 2021 Zhe Yu, Joymallya Chakraborty, Tim Menzies

We found that equalizing the class distribution in each demographic group with sample weights is a necessary condition for achieving equalized odds without modifying the normal training process.

Better Technical Debt Detection via SURVEYing

1 code implementation20 May 2019 Fahmid M. Fahid, Zhe Yu, Tim Menzies

Specifically, for ten open-source JAVA projects, we can find 83% of the technical debt via SURVEY0 using just 16% of the comments (and if higher levels of recall are required, SURVEY0can adjust towards that with some additional effort).

TERMINATOR: Better Automated UI Test Case Prioritization

2 code implementations16 May 2019 Zhe Yu, Fahmid M. Fahid, Tim Menzies, Gregg Rothermel, Kyle Patrick, Snehit Cherian

Given that much of the automated UI testing is "black box" in nature, very little information (only the test case descriptions and testing results) can be utilized to prioritize these automated UI test cases.
