Variables

var ErrOutOfBounds = x1b.ErrOutOfBounds

Functions

func Data

func Data(name string) func() (Dataset, error)

Data loads specified dataset and returns it.

func Load

func Load(path string) (train, test, distances [][]float32, neighbors [][]int, dim int, err error)

Load returns loaded vectors and so on from approximate nearest neighbor benchmark dataset.

Types

type Dataset

type Dataset interface {
	Train(i int) (interface{}, error)
	TrainSize() int
