In SAS PROC TEXTMINE, what is the purpose of the SVDINIT statement?
Select an answer to reveal the explanation.
Short Explanation
Here's the deal — you want the option that says SVDINIT specifies parameters for Singular Value Decomposition to produce latent semantic dimensions. It configures the SVD step that reduces the term-by-document matrix to a lower-dimensional latent semantic space.
Full Explanation
The correct option says SVDINIT specifies parameters for Singular Value Decomposition to produce latent semantic dimensions. In PROC TEXTMINE, SVDINIT configures the SVD step that reduces the high-dimensional term-by-document matrix to a lower-dimensional latent semantic space; parameters include the number of SVD dimensions (K=). The stop-word-list option is wrong because stop words are handled in the PARSE step. The sentiment-dictionary option is wrong because that describes sentiment analysis configuration. The LDA-random-seed option is wrong because LDA initialization uses a different statement.
