Claim 0:
1. A machine learning method of learning of a second neural network for performing a task of second class classification including a different class from first class classification using a first neural network that is a learned hierarchical neural network which has learned the task of performing the first class classification by machine learning, the method comprising:
a step of adding a new feature amount to at least one intermediate layer included in the first neural network;
a step of generating the second neural network having a structure for maintaining a structure of the first neural network without connecting the new feature amount with respect to a calculation path of an existing feature amount present in the first neural network and within a calculation path of the new feature amount, calculating a new feature amount to be added in a subsequent layer following the layer from which the new feature amount is added, by performing processing of convolving each of the existing feature amount and the new feature amount; and
a step of causing the second neural network to acquire a processing function of performing the second class classification by performing learning of the second neural network using a set of learning data in which an answer label corresponding to the second class classification is assigned.
