Data.Datamining.Clustering.Gsom.Coordinates

The network created by the GSOM algorithm is layed in two dimensions. Thus one needs to assign two dimensional coordinates to nodes of the network and for a clustering to the clusters.

The typed defining these coordinates and functions to handle them belong into this module.

type Coordinates = (Int, Int)

type Direction = Int

type Directions = [Int]

directions :: Directions

The list of supported directions. Since we are only dealing with hexagonal lattices, there are only six possible directions.

neighbour :: Coordinates -> Direction -> Coordinates

neighbour location direction calculates the coordinates of the neighbour of node with location location in direction direction.

neighbourCoordinates :: Coordinates -> [Coordinates]

neighbourCoordinates point calculates the list of coordinates which are directly adjacent to point.
