HPN(Hyperspherical Prototype Network)
softmax : cross entropy 오차 최소화 = 올바른 출력의 크기 최대화
H = the number of hidden unit in last layer
C = the number of class
HPN : 클래스 수 대신 미리 정의된 고정 차원이 있는 출력 레이어
HPN 의 출력 단위 수가 클래스 수보다 훨씬 적을 수 있으므로 많은 수의 클래스에 효율적일 수 있다.
네트워크 출력에서 미리 정의된 프로토타입까지 제곱 코사인 거리를 최소화
차원이 다르므로 네트워크가 인스턴스를 올바른 클래스의 프로토타입으로 "rotate" 하는 방법을 배워야 한다.
손실함수는 올바른 클래스의 프로토타입만 필요하다. 프로토타입 직교(벡터) -> 덜 유사한 것 분리
but, HPN 은 softmax 에 비해 거의 이점이 없다.
