    Aggregative quantification for regression 
    Bella Sanjuán, Antonio; Ferri Ramírez, César; Hernández Orallo, José; Ramírez Quintana, María José (Springer Verlag (Germany), 2014-03-01)
    The problem of estimating the class distribution (or prevalence) for a new unlabelled dataset (from a possibly different distribution) is a very common problem which has been addressed in one way or another in the past ...

    An Evaluation of Calibration Methods for Data Mining Models in Simulation Problems 
    Bella Sanjuán, Antonio (Universitat Politècnica de València, 2011-11-28)
    Data mining is useful in making single decisions. The problem is when there are several related problems and the best local decisions do not make the best global result. We propose to calibrate each local data mining ...

    On the effect of calibration in classifier combination 
    Bella Sanjuán, Antonio; Ferri Ramírez, César; José Hernández-Orallo; Ramírez Quintana, María José (Springer Verlag (Germany), 2012-06)
    A general approach to classifier combination considers each model as a probabilistic classifier which outputs a class membership posterior probability. In this general scenario, it is not only the quality and diversity of ...

    Using negotiable features for prescription problems 
    Bella Sanjuán, Antonio; Ferri Ramírez, César; Hernández Orallo, José; Ramírez Quintana, María José (Springer Verlag (Germany), 2011-02)
    Data mining is usually concerned on the construction of accurate models from data, which are usually applied to well-defined problems that can be clearly isolated and formulated independently from other problems. Although ...
