Patent ID: 11929174
Assignee: FUJIFILM CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. A machine learning method comprising:
a step of causing a first neural network that is a hierarchical neural network to acquire a processing function of performing first class classification by performing first machine learning regarding the first neural network using a first learning data set in which an answer label corresponding to the first class classification is assigned;
a step of adding a new feature amount to at least one intermediate layer included in the learned first neural network that has acquired the processing function of performing the first class classification;
a step of generating a 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 second class classification by performing second machine learning regarding the second neural network using a second learning data set in which an answer label corresponding to the second class classification including a different class from the first class classification is assigned.
