Question 1: In many research papers, researchers tend to suggest normalization of images from [-1 to 1] . How can we achieve it in code?
Question 2: What is the meaning of following line of code?
transforms.Normalize(0.5, 0.5)
Question 3: Let say I trained my model with learning rate: 0.0001 and then save the state of my model. Now I want to change learning rate to 0.00002 so should I start training from scratch? Or I could load the previous model ?
