Creates a potential based density model of a
n-dimensional vector space.
In order to calculate the density at a specific row in the table, its immediate neighborhood in the vector space is considered. The closer and more numerous the neighbors the higher is the density. The size of the neighborhood is controlled by the Radius Alpha parameter and a larger value will result in a larger neighborhood. For more details see the PBAC paper by Cebron et. al.
If the node fails due to memory problems, this is usually due to a too large radius Alpha which results in many rows with a lot of neighbors.
