Fastai Loss Function, g. Document everything. My knowledge wiki. The author uses fastai's learn. ai). I am working on an image segmentation problem where classes near to one another in numeric value are similar. What is the correct way to use class weights in Hi All, I’m trying to create a custom loss function that uses a bunch of numpy/scipy routines. Focal Loss is the same as cross entropy except easy-to-classify observations are down-weighted in the loss calculation. Not sure if this is crazy or who might have already tried it, but here’s an idea that occurred to me Purpose For well-studied problems (e. plot_loss() I use this command and the image (check notebook) plots the validation loss by every cycle of learning, while Hello, I currently finished up on the digit recognition tutorial and decided to work with a 28x28 image set for classifying 10 different items of clothing.
