Network of Neighbors
Constructs a network by connecting neighbouring instances based on distances.
Inputs
Distances: A distance matrix.
Outputs
Network: An instance of Network Graph.
Network of Neighbors constructs a network graph from a given distance matrix by connecting each instance to its nearest neighbors.
Set the number of nearest neighbors to connect each instance to.
If checked, edges are directed.
Example
We took iris.tab to visualize instance similarity in a graph. We sent the output of File widget to Distances, where we computed Euclidean distances between rows (instances). Then we sent the output of Distances to Network of neighbours to connect each instance to its two nearest neighbors. The resulting network is shown in the Network Explorer.
