Classification: CPC G | IPC G

Claim 0:
1. A recognition method comprising:
receiving user data input by a valid user for user registration;
performing on-device training on a feature extractor based on the user data and reference data corresponding to generalized users;
determining a registration feature vector based on an output from the feature extractor in response to input of the user data;
receiving test data input by a test user for user recognition;
determining a test feature vector based on an output from the feature extractor in response to input of the test data; and
performing the user recognition on the test user based on a result of comparing the registration feature vector to the test feature vector,
wherein the feature extractor includes a first neural network having a fixed parameter dependent on pretraining and a second neural network having an adjustable parameter dependent on the on-device training.
