Cosine Distance
Description
Calculates the cosine distance
Usage
CosinusDistance(Data)
Arguments
Data |
[1:n,1:d] matrix with n cases, d variables |
Details
https://en.wikipedia.org/wiki/Cosine_similarity
Value
Distance |
[1:n,1:n] symmetric matrix, containing the distanes of the cases (rows) for the given data |
Note
The cosine distance is calculated by calculating the cosine similarity d(i,j)=\max{s}-s(i,j)
, where s
is the cosine similarity and the d
the cosine distance.
