  • Analyzing and repairing concept drift adaptation in data stream classification

    Halstead, Ben; Koh, Yun Sing; Riddle, Patricia; Pears, Russel; Pechenizkiy, Mykola; Bifet, Albert; Olivares, Gustavo; Coulson, Guy (2021)
    Data collected over time often exhibit changes in distribution, or concept drift, caused by changes in factors relevant to the classification task, e.g. weather conditions. Incorporating all relevant factors into the model ...
  • Use of Ensembles of Fourier Spectra in Capturing Recurrent Concepts in Data Streams

    Sakthithasan, Sakthithasan; Pears, Russel; Bifet, Albert; Pfahringer, Bernhard (IEEE, 2015)
    In this research, we apply ensembles of Fourier encoded spectra to capture and mine recurring concepts in a data stream environment. Previous research showed that compact versions of Decision Trees can be obtained by ...
