Patent ID: 11900246
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A recognition apparatus comprising:
a processor; and
a memory including instructions executable in the processor, wherein, when the instructions are executed by the processor, the processor is configured to:
receive user data input by a valid user for user registration;
perform on-device training on a feature extractor based on the user data and reference data corresponding to generalized users;
determine a registration feature vector based on an output from the feature extractor in response to the input of the user data;
receive test data input by a test user for user recognition;
determine a test feature vector based on an output from the feature extractor in response to the input of the test data; and
perform 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 an on-device training.
