Expand description

Implemented by Input -> Output type pairs

Handles conversion to DMatrix type and stores information on associated output type. Most methods of this library can currently work with the following input -> output pairs :

InputOutputDescription
Vec<f64>f64A single, multidimensional, sample.
Vec<Vec<f64>>Vec<f64>Each inner vector is a training sample.
DMatrix<f64>DVector<f64>Using a nalgebra matrix with one row per sample.
Array1<f64>f64A single sample stored in a ndarray array (using the friedrich_ndarray feature).
Array2<f64>Array1<f64>Each row is a sample (using the friedrich_ndarray feature).

User-defined input type should implement this trait.

Required Associated Types§
