Tumor tissue and activation map (IMAGE) Ruhr-University Bochum Caption The neural network derives an activation map (on the right) from the microscopic image of a tissue sample (on the left). A hypothesis establishes the correlation between the intensity of activation that was determined solely by calculation and the identification of tumour regions that can be verified in experiments.
