impl Sampler for RandomSampler

source§

fn sample( &mut self, rng: &mut StdRng, index: &[usize], _grad: &mut [f32], _hess: &mut [f32] ) -> (Vec<usize>, Vec<usize>)

Sample the data, returning a tuple, where the first item is the samples chosen for training, and the second are the samples excluded.
