Researchers have developed SASHA (Sequential Attention-based Sampling for Histopathological Analysis), a deep reinforcement learning approach designed to efficiently analyze large histopathological images. This method uses a lightweight, attention-based multiple instance learning model to extract informative features and then selectively samples high-resolution patches, examining only 10-20% of the whole-slide image. SASHA achieves diagnostic accuracy comparable to methods that analyze entire slides at high resolution but with significantly reduced computational costs, outperforming other sparse sampling techniques.
