  • Building ensembles of adaptive nested dichotomies with random-pair selection

    Leathart, Tim; Pfahringer, Bernhard; Frank, Eibe (Springer, 2016)
    A system of nested dichotomies is a method of decomposing a multi-class problem into a collection of binary problems. Such a system recursively applies binary splits to divide the set of classes into two subsets, and trains ...
  • Ensembles of nested dichotomies with multiple subset evaluation

    Leathart, Tim; Frank, Eibe; Pfahringer, Bernhard; Holmes, Geoffrey (Springer, 2019)
    A system of nested dichotomies (NDs) is a method of decomposing a multiclass problem into a collection of binary problems. Such a system recursively applies binary splits to divide the set of classes into two subsets, and ...
  • Probability calibration trees

    Leathart, Tim; Frank, Eibe; Holmes, Geoffrey; Pfahringer, Bernhard (2017)
    Obtaining accurate and well calibrated probability estimates from classifiers is useful in many applications, for example, when minimising the expected cost of classifications. Existing methods of calibrating probability ...
