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 -> ouput pairs :

Vec<Vec<f64>> -> Vec<f64> each inner vector is a multidimentional training sample
Vec<f64> -> f64 a single multidimensional sample
DMatrix<f64> -> DVector<f64> using a nalgebra matrix with one row per sample

User-defined input type should implement this trait.

Associated Types

`type InVector: Sized`

type of the vectors storing training output data and given to methods

`type OutVector`

type of the vectors outputed when a method is called

Provided methods

`fn into_dmatrix(m: Self) -> DMatrix<f64>`

Optional: converts an owned input matrix to a DMatrix. This function is used for to reduce copies when the input type is compatible with DMatrix.

`fn into_dvector(v: Self::InVector) -> DVector<f64>`

Optional: converts an owned input vector to a DVector. This function is used for to reduce copies when the input type is compatible with DVector.
