There are two ways to extract features:
Build a feature extraction model, using a Feature Extraction node.
Use a Feature Extraction Query, one of the predictive queries.
A Feature Extraction node uses the Non-Negative Matrix Factorization (NMF) algorithm, to build models.
If Data Miner is connected to Oracle Database 12c, a Feature Extraction node uses the PCA and SVD algorithms, described in Singular Value Decomposition and Principal Components Analysis, to build models.
Note: Principal Components Analysis and Singular Value Decomposition models require Oracle Database 12c. |
