High-dimensional sparse classification dataset

Fields§

§x: Vec<Vec<f64>>

§y: Vec<usize>

Class labels for each sample

§informative_features: Vec<usize>

Indices of the informative features (columns that can be non-zero)

§feature_weights: Vec<f64>

Weight vector over features (non-zero only at informative_features)
