2008-05-19 04:26 mhall
Fixed parameter rounding (now uses Math.rint() so that, for example, -1 is not rounded to 0.
  • classifiers/meta/CVParameterSelection.java (1.27.2.4)
2008-05-16 04:19 mhall
Deleted all package names from file name of the saved file because the length of file names was getting out of hand (especially when a lot of filters are in the flow)

- getOptions returned m_DesignatedClass instead of m_ClassMode
  • classifiers/meta/ThresholdSelector.java (1.30.2.3)

Fixed bug related to computing centroids when there are empty clusters.
