• Abstract: The computer-aided disease diagnosis from radiomic data is important in many medical applications. However, developing such a technique relies on annotating radiological images, which is a time-consuming, labor-intensive, and expensive process. In this work, we present the first novel collaborative self-supervised learning method to solve the challenge of insufficient labeled radiomic data, whose characteristics are different from text and image data. To achieve this, we present two collaborative pretext tasks that explore the latent pathological or biological relationships between regions of interest and the similarity and dissimilarity information between subjects. Our method collaboratively learns the robust latent feature representations from radiomic data in a self-supervised manner to reduce human annotation efforts, which benefits the disease diagnosis. We compared our proposed method with other state-of-the-art self-supervised learning methods on a simulation study and two independent datasets. Extensive experimental results demonstrated that our method outperforms other self-supervised learning methods on both classification and regression tasks. With further refinement, our method shows the potential advantage in automatic disease diagnosis with large-scale unlabeled data available.

  We present a novel generative replay strategy to address the challenge of data heterogeneity in collaborative learning methods. A primary model learns the desired task, and an auxiliary "generative replay model" either synthesizes images that closely resemble the input images or helps extract latent variables. The generative replay strategy is flexible to use, can either be incorporated into existing collaborative learning methods to improve their capability of handling data heterogeneity across institutions, or be used as a novel and individual collaborative learning framework (termed FedReplay) to reduce communication cost.
