Type Definition linfa::dataset::Dataset

type Dataset<D, T> = DatasetBase<ArrayBase<OwnedRepr<D>, Ix2>, ArrayBase<OwnedRepr<T>, Ix2>>;

Dataset

The most commonly used typed of dataset. It contains a number of records stored as an Array2 and each record may correspond to multiple targets. The targets are stored as an Array2.

Implementations

impl<F: Float, E> Dataset<F, E>

pub fn split_with_ratio(self, ratio: f32) -> (Self, Self)

Split dataset into two disjoint chunks

This function splits the observations in a dataset into two disjoint chunks. The splitting threshold is calculated with the ratio. If the input Dataset contains n samples then the two new Datasets will have respectively n * ratio and n - (n*ratio) samples. For example a ratio of 0.9 allocates 90% to the first chunks and 10% to the second. This is often used in training, validation splitting procedures.

Parameters

• ratio: the ratio of samples in the input Dataset to include in the first output one

Returns

The input Dataset split into two according to the input ratio.
