|  | ## Generate TFIDF

#### Synopsis

Performs a TF-IDF filtering to the input data set.

#### Description

This operator generates TF-IDF values from the input data. The input example set must contain either the binary occurrences, which will be normalized during calculation of the term frequency TF, or it already contains the calculated term frequency values (in this case no normalization will be done). The behavior can be selected using the parameter calculate term frequencies.

#### Input

- example set input: expects: ExampleSetMetaData: #examples: = 0; #attributes: 0

#### Output

- example set output:
- original:

#### Parameters

- calculate term frequencies: Indicates if term frequency values should be generated (must be done if input data is given as simple occurence counts).
