Types

type MMS

type MMS struct {
	// contains filtered or unexported fields
}

func NewMMS

func NewMMS(nComponents, maxIter int, epsilon float64) *MMS

func (*MMS) FitTransform

func (mms *MMS) FitTransform(d *mat.SymDense) (*mat.Dense, float64)

FitTransform takes an n * n dissimilarity matrix d and and returns an n * MMS.r matrix of n points in r-dimensional space with distances between ith and jth points close to n[i][j] along with the final minimum value of the stress function.
