0.6.0 - 2023-12-07

Added

• Significantly extended the configuration capabilities with predefined features to limit the PSLs searchspace

Changed

• rewrote/extracted expected entropy calculation

Fixed

0.5.1 - 2023-11-24

Fixed

• PSL classifier optimization regarding global loss was incorrect

0.5.0 - 2023-11-16

Added

• _ClassifierAtK
  • Sigmoid calibration additional to isotonic
• PSL classifier
  • Make optimization loss configurable
  • Small searchspace_analyisis(·) function makes lookahead choice more informed

Fixed

• Fixed lookahead search space and considering global loss for model-sequence evaluation

Changed

0.4.2 - 2023-11-09

Fixed

• _ClassifierAtK
  • Expected entropy for stage 0 now also calculated wrt. base 2
  • Data with only 0 or 1 is now also interpret as binary data

0.4.1 - 2023-10-19

Fixed

• Small import error

0.4.0 - 2023-10-17

Added

Added

• PSL classifier can now run with continuous data and optimally (wrt. expected entropy) select thresholds to binarize the data

Changed

• Significantly improved optimum calculation for MinEntropyBinarizer (the same optimization algorithm is shared with the psls internal binarization algorithm)

0.2.0 - 2023-08-10

Added
