Method alpha

src/opt.rs:86–92

Sets the learning rate. # Example ``` use rustml::opt::*; let opts = empty_opts().alpha(0.2); assert_eq!(opts.alpha.unwrap(), 0.2); ```

(&self, val: T)

    /// assert_eq!(opts.alpha.unwrap(), 0.2);
    /// ```
    pub fn alpha(&self, val: T) -> OptParams<T> {
        OptParams {
            alpha: Some(val),
            iter: self.iter.clone(),
            eps: self.eps.clone(),
        }
    }

    /// Sets the maximum number of iterations.
