Protein localization information is essen-tial for understanding protein functions and their roles in various biological processes.The image-based prediction methods of protein subcellular localization have emerged in recent years because of the advantages of microscopic images in revealing spatial expression and distribution of proteins in cells.However,the image-based prediction is a very challenging task,due to the multi-instance nature of the task and low quality of images.In this paper,we pro-pose a multi-task learning strategy and mask generation to enhance the prediction performance.Furthermore,we also investigate effective multi-instance learning schemes.We collect a large-scale dataset from the Human Protein Atlas database,and the experimental results show that the proposed multi-task multi-instance learning model outperforms both single-instance learning and common multi-instance learning methods by large margins.
