Broken SVM RBF kernel #58

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
1. Open Workbench
2. Add new network
3. Set network type to SVM
4. Set kernel to RBF
5. Topology I used is 64 inputs and 4 outputs, tried both ESV and NSW 
regression.
6. Try to train or evaluate network

Reworked much of the SVM interface as part of Encog 3.0, I believe this is 
fixed in Encog 3.0.
