By default, a Feature Extraction node builds one model using the NMF algorithm.
If you are connected to Oracle Database 12c, the node builds two models by default: an NMF model and a PCA model; you can add SVD models.
All models in the node use the same build data and have the same Case ID, if you specify a Case ID.
