Changeset 2290 for trunk


Ignore:
Timestamp:
08/14/09 19:56:04 (15 years ago)
Author:
gkronber
Message:
  • introduced a variablename to index mapping for SVM models (to make sure we can use the model for prediction in the model analyzer)
  • added support to enable and disable algorithms in the dispatcher and removed DispatcherBase
  • fixed bugs when calculating variable impacts and reading the final model of GP algorithms

#722 (IModel should provide a Predict() method to get predicted values for an input vector)
