EM Baggenstoss: mode_dist

Description

Distance (actually closeness) measure between 2 modes with means m1, m2 and cholesky covariance matrices v1, v2. Returns negative closeness measure (for identical modes, d = 0).

Usage

mode_dist(Mean1, Mean2, Covariance1, Covariance2)

Arguments

Mean1

Numerical vector with mean of first mode (d-dimensional where d denotes the features dimension).

Mean2

Numerical vector with mean of second mode (d-dimensional where d denotes the features dimension).

Covariance1

Numerical matrix with covariance matrix of first mode (dxd matrix where d denotes the feature's dimension).

Covariance2

Numerical matrix with covariance matrix of second mode (dxd matrix where d denotes the feature's dimension).

Value

List with one element:

Dist

Numerical value with distance of two modes.
