Web1 day ago · The model is the classic one as in the code below but the thing is that the loss function plays a big role for the predictions on the Test set. I used 'binary_crossentropy' and 'mean_squared_error' and the predictions look pretty good for most images but I researched other loss functions and found about Dice Loss and when I used it for the ... WebAIC helps you choose the model that best predicts your data; it is equivalent to leave-one-out cross-validation in large samples. This is telling you that the model without the interaction predicts the data better, which is nice because it makes interpretation easier. Lower AIC = better model.
