Frequently asked questions

How can I reduce the memory footprint of large machine learning models?

scaler = GradScaler()

What does it mean to evaluate the output of a model?

output = model(input)

How do I calculate the loss function in a machine learning model?

loss = criterion(output, target)

What is the purpose of scaling the loss before backpropagation?

scaler.scale(loss).backward()
