Title: Machine Learning for Biomedical Images in Low-Data Regime

Abstract: Diagnostic pathology and histopathology images play a critical role in the diagnosis and treatment of carcinomas. In order to get satisfying performance, we usually need a large amount of labeled data. Annotating a large number of histopathology images for training machine learning models can be expensive and time-consuming. We explored several approaches of machine learning in a low-data regime for histopathology images, including caption generation from histology images [Zhang et al., 2020b], a deep Bayesian active learning method [Zhang et al., 2023] to enable efficient selection of training examples that can undergo more expensive annotation, and representation learning approach that utilize existing coarse-grained labels for H&E slides to improve model performance on fine-grained data. Our experiments demonstrate that these approaches can improve the accuracy of models in the low-data regime while maintaining high levels of interpretability. The results of this study provide valuable insights for future research in the area of machine learning in low-data regimes for histopathology images.
