Unsupervised learning for cell-level visual representation in histopathology images with generative adversarial networks
IEEE journal of biomedical and health informatics, 2018•ieeexplore.ieee.org
The visual attributes of cells, such as the nuclear morphology and chromatin openness, are
critical for histopathology image analysis. By learning cell-level visual representation, we
can obtain a rich mix of features that are highly reusable for various tasks, such as celllevel
classification, nuclei segmentation, and cell counting. In this paper, we propose a unified
generative adversarial networks architecture with a new formulation of loss to perform robust
cell-level visual representation learning in an unsupervised setting. Our model is not only …

The visual attributes of cells, such as the nuclear morphology and chromatin openness, are critical for histopathology image analysis. By learning cell-level visual representation, we can obtain a rich mix of features that are highly reusable for various tasks, such as celllevel classification, nuclei segmentation, and cell counting. In this paper, we propose a unified generative adversarial networks architecture with a new formulation of loss to perform robust cell-level visual representation learning in an unsupervised setting. Our model is not only label-free and easily trained but also capable of cell-level unsupervised classification with interpretable visualization, which achieves promising results in the unsupervised classification of bone marrow cellular components. Based on the proposed cell-level visual representation learning, we further develop a pipeline that exploits the varieties of cellular elements to perform histopathology image classification, the advantages of which are demonstrated on bone marrow datasets.
