classification by machine learning has already established a variety of excellent results. The classifications of machine learning models are not always understandable for human, so that many researches are trying to visualize areas positively cotributing a classification in an image. However, negative contributions, which are important to diagnose an medical images, have not been paid attention. We propose a new analysis technique named DiDA to visualize positive and negative contribution areas in an image, using sets images with small difference to the original. An image masked along the grid is input to a target machine learning model and its result is compared with the result of the original. Positive and negative differences are represented as different colors in an analyzed grid image. Multiple grid sizes are used for visualizing contributing areas precisely. We applied the DiDA to classifications of optical coherence tomography (OCT) images by mechine learning. The results were checked by a doctor and we found colored areas in resulted images shows appropriate points for diagnoses.
