SOM Plot

Hi,

I'm trying to make a SOM Plot for my database. I have:

26.000 records
13 input variables

I'm trying to make the map after the normalization of the data. I'm also defining:
Net width = 5
Net Height = 5
Training Rounds = 1 
Adaptations Radius = 3

The program starts the calculation, but never ends it neither gives any message of error.

What am I doing wrong?

Thaks,

RS

Re: SOM Plot

Hi RS,

I could reproduce this error for large data sets and I have created an internal bug report. As a workaround you could try to plot only parts of the data. Use the Sample operator to create a suitable sample.

Best regards,
Marius
