RapidMiner AutoModel some models are grayed out
I was trying RapidMiner AutoModel with a dataset used on a previous project. Some model options were grayed out, for example Deep Learning and Gradient Boosted Trees. It would be very helpful to provide the reason why a model is grayed out, so that I can make the necessary adjustments to the data. Currently, I have the guess the reason, and have no way to know for sure if it's, for example, because I need to reduce the number of examples, reduce the number of features, transform non-numeric features to numeric, handle missing data, or any other reason.
