MATLAB: How to label unlabeled data(e.g. 200*2 matrix) in Self Organizing Map

data labelsomunified matrix

Hallo Everybody,

I need a little help.

I have a 200*2 matrix, which contains 200 samples of 2 variable. i want to map this dataset in Self Organizing Map. I already did. But i want to have U-Matrix (Unified Distance Matrix), which shows that, which data samples(Variable 1 or 2) clustered in which neuron?

I guess i have to label the dataset. But how can i label my dataset?

What is the matlab command to test a dataset in a trained SOM network?

I am using MATLAB 2017a.

I will be very greatful if someone help me to get out of this prolam.

Thank you in anticipation.

with Regards

If you already know the label of histirical data, then you can just make an cell array and labeled them as the historical dataset. Then you can train them with SOM and can find the node positions.

Difference in performance can be caused by different random initial weights.

Be sure you have initialized the RNG to the same state.
