i want to save the weights from plotsomPlanes so that i could use these waiegts as input for another network like ANFIS to improve the results is it possible? please guide

thank you

Hi Shazia,

I understand that you want to save the weights from the plotsomPlanes function to use in some other network like ANFIS.

It's possible to use the weights obtained from the ‘plotsomPlanes’ function in the SOM network as inputs to other machine learning algorithms like ANFIS to improve their results.

We can extract the weights of the SOM neurons by accessing the children property of the plot object.

Please refer to the below code snippet

data = load('sample_data.mat');
net = selforgmap([10 10]);
net = train(net, data.inputs');
plotsomPlanes(net);
% Extract SOM weights
plot_obj = gcf; % Get handle of the SOM plots
weights = [];
for i = 1:length(plot_obj.Children)
    if isa(plot_obj.Children(i), 'matlab.graphics.primitive.Image')
        weights = [weights; plot_obj.Children(i).CData(:)'];
    end
end
% Use SOM weights as input to ANFIS
anfis_in = [data.inputs', weights];
anfis_out = data.targets';
anfis_model = anfis(anfis_in, anfis_out);
