Struct ArrayDataProvider 

Source 
pub struct ArrayDataProvider { /* private fields */ }
Expand description

In-memory data provider backed by owned Array2<f32> features and Array1<f32> targets.

Implementations§

Source§

impl ArrayDataProvider

Source

pub fn new(features: Array2<f32>, targets: Array1<f32>) -> Self

Create a new provider.

§Panics (debug only)

In debug builds asserts that features.nrows() == targets.len().
