Neural Style Transfer(3),(4) : Cost Function, Content Cost Function

(3) Cost Function Neural style transfer cost function 스타일을 접목시켜 생성하는 이미지에 대한 cost function은 굉장히 독특하게 정의되네요. 기존 이미지 C와의 cost function과 스타일 이미지 S의 cost function에 각각 가중치를 부여한 것의 합으로 정의됩니다. Find the generated image G 이미지 G를 생성하는 방식은 이전의 CNN과 동일합니다. 다만 input이 없으므로 random하게 초기화하는 것에서만 차이가 존재합니다. 학습을 거듭함에 따라 gradient descent를 적용하여 cost function을 최소화하는 방향으로 최적화됩니다. (4) Content Cost Function content cost..
