pub struct FittedCountVectorizer { /* private fields */ }Expand description
A fitted count vectorizer holding the learned vocabulary.
Created by calling CountVectorizer::fit.
Implementations§
Source§impl FittedCountVectorizer
impl FittedCountVectorizer
Sourcepub fn vocabulary(&self) -> &[String]
pub fn vocabulary(&self) -> &[String]
Return the vocabulary as a sorted slice of terms.
Sourcepub fn vocabulary_map(&self) -> &HashMap<String, usize>
pub fn vocabulary_map(&self) -> &HashMap<String, usize>
Return the vocabulary mapping (term -> column index).
Sourcepub fn transform(&self, docs: &[String]) -> Result<Array2<f64>, FerroError>
pub fn transform(&self, docs: &[String]) -> Result<Array2<f64>, FerroError>
Transform documents into a term-count matrix.
§Errors
Returns FerroError::InsufficientSamples if docs is empty.
