Struct AdasynStrategy

pub struct AdasynStrategy { /* private fields */ }

ADASYN (Adaptive Synthetic Sampling) implementation

ADASYN improves upon SMOTE by focusing synthetic sample generation on minority class examples that are harder to learn, determined by their k-nearest neighbor density distribution.

Implementations

impl AdasynStrategy

pub fn new(k_neighbors: usize, beta: f64) -> AdasynStrategy

Create a new ADASYN strategy

pub fn default() -> AdasynStrategy

Create with default configuration
