Implementations

impl<T> Encoder<T>

where T: Hash + Eq + Clone + Debug,

pub fn new(enctype: Option<EncoderType>) -> Encoder<T>

pub fn fit(&mut self, data: &Vec<T>, config: &Config<T>)

Fit label encoder given the type (ordinal, one-hot, custom)

pub fn transform(&self, data: &Vec<T>) -> Transform

Transform data to normalized encoding

pub fn inverse_transform(&self, data: &Transform) -> Vec<T>

Transforms labels back to the original data (not necessarily true with custom encoder)

pub fn nclasses(&self) -> usize

Return number of unique categories
