Build PyTorch Model, Training Loop, and Evaluate Objective Function Now we can use the selected hyperparameter values saved in params dictionary to build a PyTorch model. Next, we will train the model and evaluate our objective function, which in our case is the accuracy. Run Hyperparameter Tuning

Dec 13, 2021 · We will write the code to carry out manual hyperaparameter tuning in deep learning using PyTorch. A few of the hyperparameters that we will control are: The learning rate of the optimizer. The output channels in the convolutional layers of the neural network model. The output features in the fully connected layers of the neural network model.
