Types

type Clusterer

type Clusterer interface {
	Normalize()
	InitCentroids()
	Cluster() ([][]float64, error)
	SSE() float64
}

type DistanceFunction

type DistanceFunction func(v1, v2 *mat.VecDense) float64

DistanceFunction is a function that computes the distance between two vectors NOTE: clusterer already ensures that the all the input vectors are of the same length, so we don't need to check for that here again and return error if the lengths are different.

type DistanceType

type DistanceType uint16

const (
	L2Distance DistanceType = iota
	InnerProduct
	CosineDistance
)

type InitType

type InitType uint16

const (
	Random InitType = iota
)
