Struct FtrlConfig 

pub struct FtrlConfig {
    pub alpha: f64,
    pub beta: f64,
    pub l1: f64,
    pub l2: f64,
}

Configuration for FTRL models.

Controls the per-coordinate learning rate and regularization strengths. All fields must be finite; alpha must be strictly positive and the regularization parameters must be non-negative.

Fields

alpha: f64

Alpha: learning rate scaling. Must be > 0.

beta: f64

Beta: smoothing constant. Must be >= 0.

l1: f64

L1 regularization strength. Must be >= 0.

l2: f64

L2 regularization strength. Must be >= 0.
