Struct DatasetInput 

pub struct DatasetInput<'a> {
    pub features: DenseMatrix<'a>,
    pub label: &'a [f32],
    pub weight: Option<&'a [f32]>,
    pub group: Option<&'a [u32]>,
    pub feature_names: Option<Vec<String>>,
    pub categorical_features: Vec<usize>,
}

One rank’s rows and their metadata.

Fields

features: DenseMatrix<'a>

label: &'a [f32]

weight: Option<&'a [f32]>

group: Option<&'a [u32]>

Query sizes (LightGBM group): consecutive runs of rows.

feature_names: Option<Vec<String>>

Defaults to Column_<i>, as LightGBM names unnamed columns.

categorical_features: Vec<usize>
