Summary:Disclosed are an electronic device and a controlling method thereof. The disclosed electronic device of the present disclosure may comprise: a memory which stores a pre-trained neural network model and training data; and a processor which obtains a first loss function by using a label corresponding to the training data and output data obtained by inputting the training data into the neural network model, obtains the magnitude of the change amount of a weight of each of a plurality of layers included in the neural network model on the basis of the first loss function, and trains the neural network model by updating a weight of at least one layer in which the magnitude of the change amount of the weight exceeds a first threshold value, among the plurality of layers. Accordingly, a user may train the neural network model based on personal learning data on a terminal device having limited memory and computing power. 전자 장치 및 이의 제어 방법이 개시된다. 본 개시의 전자 장치는 기 학습된 신경망 모델 및 학습 데이터를 저장하는 메모리 및 학습 데이터를 신경망 모델에 입력하여 획득된 출력 데이터 및 학습 데이터에 대응되는 라벨을 이용하여 제1 손실 함수를 획득하고, 제1 손실 함수에 기초하여 신경망 모델에 포함된 복수의 레이어 각각의 가중치의 변화량 크기를 획득하고, 복수의 레이어 중 가중치의 변화량의 크기가 제1 임계값을 초과하는 적어도 하나의 레이어의 가중치를 업데이트하여 신경망 모델을 학습시키는 프로세서가 포함될 수 있다.
