SOM - neural networks

1.1k Views Asked by At

Can anyone tell me if it's possible and how to create neural network from a matrix 60 x 5, which describes 60 cities in 5 different parameters (population, bugdet, area, schools, hospitals). The final results should be presented as following: similar (cities)nodes should be grouped close - I want to see diversity and similarity of collected data. Any help and suggestion is welcome. best regards

You are referring to a clustering result.

This could be acheived using a Self-Organizing Map (SOM) or any other variation of SOM. I would suggest you to go through the wiki link I have given to know more about the SOM.

If you choose to use the SOM and has one set up try experimenting with the map size and the learning rate to find the optimal level of clustering required.

You can use the following links to find implementations of SOM

  1. Matlab
  2. Java and more variations of SOM
