I have a question about the nprtool GUI.
Is it necessary to normalize the inputs before importing them into the tool? or does the tool normalize the inputs for you?
The tool gives you the option to load example data sets, such as iris flowers, wine vintage, types of glass and breast cancer.
The inputs to some of these example data sets do not appear to be normalized. Or are they? I can' tell.
No products are associated with this question.
Typically, input and target data need to be normalized.
To check for normalization calculate the summary statistics
minmax(input) % Check for identical mins and maxes
mean(input,2) % Check for zero means
std(input,0,2) % Ckeck for unit standard deviations
Hope this helps.
