Evacuation Shelter Scheduling Problem

no code implementations26 Nov 2021 Hitoshi Shimizu, Hirohiko Suwa, Tomoharu Iwata, Akinori Fujino, Hiroshi Sawada, Keiichi Yasumoto

In this study, we formulate the "Evacuation Shelter Scheduling Problem," which allocates evacuees to shelters in such a way to minimize the movement costs of the evacuees and the operation costs of the shelters.

Learning Individually Fair Classifier with Path-Specific Causal-Effect Constraint

no code implementations17 Feb 2020 Yoichi Chikahara, Shinsaku Sakaue, Akinori Fujino, Hisashi Kashima

To avoid restrictive functional assumptions, we define the {\it probability of individual unfairness} (PIU) and solve an optimization problem where PIU's upper bound, which can be estimated from data, is controlled to be close to zero.

Higher-Order Factorization Machines

4 code implementations NeurIPS 2016 Mathieu Blondel, Akinori Fujino, Naonori Ueda, Masakazu Ishihata

Factorization machines (FMs) are a supervised learning approach that can use second-order feature combinations even when the data is very high-dimensional.
