New issue 9 by kyle.tha...@gmail.com: Handle missing values in data sets
http://code.google.com/p/ifcsoft/issues/detail?id=9
From loading through the SOM algorithm, IFC Soft should allow data points
to have missing values. Currently, when reading a file, if it finds a
missing value, it throws out the data point.
In the SOM algorithm, if a value is missing, the data point can still be
placed based on the dimensions it has, and it should then only modify those
dimensions which it has.
For WRCs, perhaps the wedge could be given a size of 1/2, but somehow be
marked as N/A.

I started a thread to discuss how to solve this and issue 10:

Progress on this has been started on this clone:

I'm thinking it would be good to give an option to use
1) All data points regardless of what they are missing
2) Only data points with at least half of the used dimensions
3) Only use data points that have all the used dimensions
