WebJul 25, 2024 · Optimizers in machine learning are used to tune the parameters of a neural network in order to minimize the cost function. The choice of the optimizer is, therefore, an important aspect that can make the difference between a good training and bad training. Actually, there are many optimizers and so the choice is not straightforward. WebYou can find the optimizer in the main method: optimizer = optim.SGD (self.net.parameters (), lr=0.01, momentum=0.99) That's all we need to do for the optimizer. 3. Augmentations As we are not dealing with biomedical images we'll use our own augmentations. You can find the code in img.augmentation.augment_img.
