Default Behavior for Feature Extraction Node

By default, a Feature Extraction node builds one model using the Non-Negative Matrix Factorization (NMF) algorithm.

If you are connected to Oracle Database 12c, the node builds two models by default:

• NMF model

• 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.
