The document discusses Baidu Research's use of deep learning to help pathologists find tumors. It describes how reviewing pathology slides can be difficult due to their large size and complexity. Most existing methods use patch-based deep CNN classifiers to label patches as tumor or normal, but these do not capture spatial correlations. The document presents Baidu's new NCRF method, which captures spatial correlations and outperforms previous methods, achieving an FROC score of 0.8096 on a test set. The paper on this method was accepted to MIDL 2018 and the code has been open sourced.
