- Reworked cost sensitive classification and evaluation. Cost matrices are
30
now handled as a class CostMatrix. Code related to cost matrices has been
31
moved from Instances into CostMatrix. Evaluation has been updated to use
32
CostMatrix (and the old cost file format is still read). Created a meta
33
classifier for performing cost-sensitve classification using either
34
training instance reweighting or minimum expected cost prediction. Made a
35
simple editor for cost matrices and adjusted other GUI files to support
38
- Also made some small GUI layout changes.
