WebOct 29, 2024 · The implementation of a label smoothing cross-entropy loss function in PyTorch is pretty straightforward. For this example, we use the code developed as part of the fast.ai course. First, let us use a helper function that computes a linear combination between two values: Next, we implement a new loss function as a PyTorch nn.Module. WebMay 22, 2024 · (하지만 저의 post에서도 설명했듯 흑백 이미지는 픽셀이 0이냐 1이냐로 나눌 수도 있기 때문에 Binary Cross Entropy (BCE)를 사용해서 학습해도 됩니다.) 마지막으로 학습 결과로 Encoder가 어떻게 mnist 이미지를 학습했는지 보도록 하겠습니다.
