Training a neural network involves feeding forward data, comparing the predictions with the ground truth, generating a loss value, computing gradients in the backwards pass and subsequent optimization. Combining the two of them allows for automatic tuning of hyperparameters to find the best . The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning. So today, we want to train a baseline model. I recently started working with Pytorch-lightning, which wraps much of the boilerplate in the training-validation-testing pipelines. By clicking “Sign up for GitHub”, you agree to our terms of service and If I had not told you that we are aiming at quantization, you could hardly tell the difference between these steps and training any PyTorch Lightning model for deployment.
