인공신경망은 1940년대에 이미 개발된 방법 선형 맞춤(linear fitting)과 비선형 변환(nonlinear transformation or activation)을 반복해 쌓아올린 구조 영상처리, 인공지능, 제어 등 다양한 분야에 적용 최적화 알고리즘 역전파(back propagation) 방법 제프리 힌톤(Geoffrey Hinton) 데이터의 전처리과정(pre-training) 2006년의 논문, A fast learning algorithm for deep belief nets 인공신경망의 각 층을 먼저 비지도 학습방법(unsupervised learning)을 통해 잘 손질해주고, 그렇게 전처리한 데이터를 여러 층 쌓아올려 인공신경망 최적화를 수행하면 훌륭한 결과를 만들어 낼 수 있다. 참..
