The Neural Net Clustering app leads you through solving a clustering problem using a self-organizing map (SOM). It helps you select data, define the network architecture, and train the network. You can select your own data from the MATLAB^® workspace or use one of the example datasets. After training the network, analyze the results using various visualization tools. You can then evaluate the performance of the network on a test set. If you are not satisfied with the results, you can retrain the network with modified settings or on a larger data set.
