Estimation of conditional average treatment effects on distributed data: A privacy-preserving approach

no code implementations5 Feb 2024 Yuji Kawamata, Ryoki Motai, Yukihiko Okada, Akira Imakura, Tetsuya Sakurai

Second, our method enables collaborative estimation between different parties as well as multiple time points because the dimensionality-reduced intermediate representations can be accumulated.

Non-readily identifiable data collaboration analysis for multiple datasets including personal information

no code implementations31 Aug 2022 Akira Imakura, Tetsuya Sakurai, Yukihiko Okada, Tomoya Fujii, Teppei Sakamoto, Hiroyuki Abe

This study then proposes a non-readily identifiable DC analysis only sharing non-readily identifiable data for multiple medical datasets including personal information.

Another Use of SMOTE for Interpretable Data Collaboration Analysis

no code implementations26 Aug 2022 Akira Imakura, Masateru Kihira, Yukihiko Okada, Tetsuya Sakurai

DC analysis centralizes individually constructed dimensionality-reduced intermediate representations and realizes integrated analysis via collaboration representations without sharing the original data.

Collaborative causal inference on distributed data

no code implementations16 Aug 2022 Yuji Kawamata, Ryoki Motai, Yukihiko Okada, Akira Imakura, Tetsuya Sakurai

Many existing methods for distributed data focus on resolving the lack of subjects (samples) and can only reduce random errors in estimating treatment effects.

Application of Particle Swarm Optimization method to On-going Monitoring for estimating vehicle-bridge interaction system

no code implementations20 Jan 2022 Kyosuke Yamamoto, Kakeru Murakami, Ryota Shin, Yukihiko Okada

Using the particle swarm optimization (PSO) method, the vehicle and bridge parameters and the road unevenness can be estimated by updating the parameters to minimize the objective function.

Interpretable collaborative data analysis on distributed data

no code implementations9 Nov 2020 Akira Imakura, Hiroaki Inaba, Yukihiko Okada, Tetsuya Sakurai

This paper proposes an interpretable non-model sharing collaborative data analysis method as one of the federated learning systems, which is an emerging technology to analyze distributed data.
