Deep learning basics, neural networks, supervised … WebApr 8, 2024 · In training steps, we’ll need a criterion to measure the loss between the original and the predicted data points. This information is crucial for gradient descent … WebApr 8, 2024 · PyTorch allows us to do just that with only a few lines of code. Here’s how we’ll import our built-in linear regression model and its loss criterion from PyTorch’s nn package. 1 2 model = torch.nn.Linear(1, 1) criterion = torch.nn.MSELoss() The model parameters are randomized at creation. We can verify this with the following: 1 2 cybersecurity qualification
