"Zero Weights in LibSVMLearner / JMySVMLearner"
Hi,
I get all weights to be zero (i have used 200 attributes) in the LibSVM / JMySVM classification procedures. And this happens only for certain data. What are the circumstances where the weights corresponding to all the attributes will be zero? (Any specific cases?)
For example: I used LibSVMLearner for a data and I get non-zero weights for most of the attributes. But if I use JMySVMLearner for the same data, I get the weights of all 200 attributes to be zero. What could be the problem?....
Thanks,
Shubha
