Overview of AI techniques and algorithm development in computational pathology for GI cancers. AI is a concept that mimics human intelligence with respect to learning and problem solving. Deep learning is a subset of machine learning; both are techniques used for the development of AI to study the patterns or relationships in WSIs. Deep learning-based techniques are capable of automatic feature extraction, whereas machine-learning-based techniques require manually designed features. Existing software, algorithms and network architectures discussed in this study are summarized in the figure.
