Kohonen Neural Network Experimentations

A few weeks ago I updated my Kohonen neural network code to support circular rows and viagra sale cheap columns as well as some simple additional visualizations which allowed for some interesting experimentation.

Circular rows and columns follow a simple premise — the neighbourhood influence effect of training can now wrap around both row and column, allowing for circular, cylindrical and torodial geometries.

Think of it like this, a network with a single row wrapped around allows for a network to learn a circular topology. A nice, simple example of this is the Travelling Salesman Problem as you need one continuous, circular route to be determined. Below there is cheap dream pharmaceutical viagra an example of a Kohonen network run over 350 iterations. The initial phase starts to spread the nodes out over the map, with the second phase making more localized adjustments:

Kohonen-based TSP Solver

It is worth noting that the viagra cheapest online Kohonen-based solver isn’t perfect, sometimes choosing interim junctions where there is no city, but it is an interesting, reasonably practical use of a different kind of strattera for sale Kohonen topology.
