Introduction to Quantization on PyTorch PyTorch

WebMar 12, 2024 · The accuracy () function is defined as an instance function so that it accepts a neural network to evaluate and a PyTorch Dataset object that has been designed to work with the network. The idea here is that you created a Dataset object to use for training, and so you can use the Dataset to compute accuracy too. [Click on image for larger view.] WebMar 25, 2024 · It was around 57% accurate previously. But here, we get a perfect prediction. Partially because the model is simple, a one-variable logsitic function. Partially because we set up the training correctly. Hence the cross-entropy loss significantly improves the model accuracy over MSE loss as we demonstrated in our experiments. dally is afraid that jail will
