WebSep 11, 2024 · Yes, fc2 doesn’t return softmax. If you want to get Softmax out of the output, you should write output.softmax (). While technically it is more correct, it won’t change the result of prediction - if you look into the VQA example they use argmax to get the final results: output = np.argmax (output.asnumpy (), axis = 1). WebApr 20, 2024 · Softmax GAN is a novel variant of Generative Adversarial Network (GAN). The key idea of Softmax GAN is to replace the classification loss in the original GAN with a softmax cross-entropy loss in the sample space of one single batch.
