Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we propose a continual federated learning that can continuously learn distributed data generated daily by multiple organizations to maintain high performance. Specifically, we propose a method for efficiently selecting a dataset for replay from past training data to achieve high-performance continual learning and incorporate it into eFL-Boost, a federated learning for gradient boosting decision tree model proposed by Yamamoto et al. This enables robust prediction even for non-stationary data by communicating only statistical information with a low risk of information leakage between organizations and selecting optimal data for replay.
