Of course, if you chose to use a CNN (rather than an MLP) because you are dealing with images, then you will probably get better performance. grand rapids republican party

"WebDoes increasing the number of trees has different effects on overfitting depending on the model used? So, if I had 100 RF trees and 100 GB trees, would the GB model be more likely to overfit the training the data as they are using the whole dataset, compared to RF that uses bagging/ subset of features?
