Asia-Pacific Working Group
Our group caters for the MD4SG community in the Asia Pacific region. Because we are on the opposite side of the globe to the United States, our timezone is not a good match for many MD4SG events. We meet online every second Tuesday at 16h00 AEST. Please contact the working group organizer if you would like to join the group. We focus on a variety of topics, much like the very first MD4SG working group.
Summary of the 2020 sessions
Market Design in Education
Led by Kentaro Tomoeda.
Reading: What Really Matters in Designing School Choice Mechanisms by Parag Pathak.
Highlights:
- In designing school choice mechanisms, what's important in theory may not be important in practice... getting involved with implementing a mechanism highlights these cases.
- Strategyproofness (best response is to report the truth) does not guarantee truthful reporting in practice.
Diversity in Education Markets
Led by Emil Temnyalov.
Reading: "Explicit vs. Statistical Targeting in Affirmative Action: Theory and Evidence from Chicago's Exam Schools" (2020) by by Umut Dur, Parag Pathak and Tayfun Sönmez.
Highlights:
- Subtle details of mechanisms can have big impacts on outcomes. These details can be used as a lever for policymakers.
Fairness and Predictive Policing
Led by Ashley Khor.
Readings: A Snapshot of the Frontiers of Fairness in Machine Learning by Alexandra Chouldechova and Aaron Roth and page 131-141 of Predictive Policing: The Argument for Public Transparency by Erik Bakke.
Highlights:
- Concern that profit driven organisations generate most of the predictive solutions. Should there be more citizen involvement and oversight? The article by Erik Bakke suggests that transparency should be a mandatory feature of predictive policing.
- Open question on what the normative properties a predictive policing algorithm should satisfy.
Defining Fairness
Led by Jaeho Lee.
Reading: Prediction-Based Decisions and Fairness: A Catalogue of Choices, Assumptions, and Definitions by Shira Mitchell, Eric Potash, Solon Barocas, Alexander D'Amour, and Kristian Lum.
Highlights:
- The current ML pipeline imposes unintended fairness threats that are often hard to detect or quantify. Even the clearest cases have subtle issues.
- Impossibility results show that some definitions of fairness cannot be satisfied simultaneously.
Applications of Remote Sensing
Led by Gabriel Tseng.
Reading: Machine learning can help get COVID-19 aid to those who need it most by Joshua Blumenstock.
Highlights:
- Many regions, especially in Africa, have a lack of training data for remote sensing, a challenge which Gabriel has faced in his own work. Gabriel described how he tackled this challenge when his team was asked to deliver maps of farms for the Togolese government in rapid time.
- Can remote sensing allow us to sidestep the information assymetry at the heart of many mechanism design problems?
Foster Care
Led by Allan Hernández-Chanto.
Reading: Review of the Foster Care System by the Queensland Family & Child Commission
Highlights:
- The foster care system has unique characteristics that differ from popular applications of market design, such as school choice. The system is complex, has many stakeholders, involves a dynamic matching problem, and has multiple avenues to exit the system.
- Allan described the foster care system in Queensland. He noted that it has become increasingly difficult for the state to recruit foster parents.
