kNN distance matrix
The kNN distance matrix is a necessary prior step to producing the kNN distance score. The distance matrix has
- \(n\) rows, where \(n\) is the number of data points
- \(k\) columns, where \(k\) is the user-chosen number of neighbors.
The entry in row i and column j of the distance matrix is the distance between point i and its jth nearest neighbor.
