摘要：Survival models finds vast applications in biomedical studies. However, survival data used to train these models are usually distributed, censored and facing a growing concern for data privacy. In addition to these issues, it is less commonly recognized that survival times are usually skewed. In this study, we attempt to tackle such challenges via a novel federated learning scheme. The proposed scheme aims to mitigate the censoring and tailed data problems via data augmentation using multi-task variationalautoencoder(MVAE). Experimental results from extensive simulated and real world survival datasets have demonstrated the effectiveness of the proposed methodology with possible deployments at the server or the clients.
