Abstract
There are provided machine learning device and method which can prepare divided data suitable for machine learning from volume data for learning. A machine learning unit () calculates detection accuracy of each organ O(j,i) in a predicted mask Pj using a loss function Loss. However, the detection accuracy of the organ O(k,i) with a volume ratio A(k,i)<Th is not calculated. That is, in the predicted mask Pk, the detection accuracy of the organ O(k,i) with a volume ratio that is small to some extent is ignored. The machine learning unit () changes each connection load of a neural network () from an output layer side to an input layer side according to the loss function Loss.
