이미지가 개인지 고양이인지를 예측하기 위해 CNN 모델을 만들었지 만, 출력에서 예측 한 것이 무엇인지 알 수 없습니다. 아래를 참조 출력으로예상 내용은 무엇입니까? CNN Keras

는하지만 방법을 알고 예측이이라고 말한다면 개 또는 고양이. 손에이 결과가 있으면 이미지가 개인지 고양이인지 아직 알 수 없습니다.
누군가 * really * basic * 튜토리얼을 읽어야합니다. 이것을 무시하면 앞으로는별로 재미 있지 않을 것입니다. * 힌트 * : 마지막 레이어를보십시오.'''fcl3 = Dense (2, activation = 'softmax')''', 입력 형태와 손실! – sascha
입력 모양에 어떤 문제가 있습니까? – Leo
나는 뭔가 잘못되었다고 말하지 않았다. 나는 결과를 해석하는 것과 관련하여 3 가지 가장 중요한 것을 암시했다. – sascha
