Hi everyone,
I have a question here. I have data for creating SOM map, and first steps it seems to be fine, but when I did for normalization of SOM, I have an error (you can see it below- in the Bold words).
Anyone know this error, please tell me how can I fix it?
Thank you so much in advance!
>> %% NHAP DU LIEU
>> sD = som_read_data('C:\Users\quang\Desktop\Data.txt');
Warning: Automatically determined data dimension is 8. Is it
correct?
> In som_read_data (line 187)
data read ok
>> %% XU LY DU LIEU
>> sD = som_normalize(sD,'range');
>> %% HUAN LUYEN DU LIEU
>> sM = som_make(sD);
