ELECTRONIC APPARATUS AND CONTROL METHOD THEREOF

An electronic apparatus includes a memory storing an artificial intelligence model and at least one processor configured to identify a first activation function used in at least one layer of the artificial intelligence model, obtain a second activation function by adding a first periodic function corresponding to a first time interval to the first activation function, apply the second activation function to an output layer during the first time interval, obtain a third activation function by adding a second periodic function corresponding to a second time interval to the first activation function, and update the artificial intelligence model by applying the third activation function to the output layer during the second time interval.
