• Distributed Learning Automata-based S-learning scheme for classification 

      Goodwin, Morten; Yazidi, Anis; Jonassen, Tore Møller (Pattern Analysis and Applications;Published online 12 October 2019, Journal article; Peer reviewed, 2019-09-10)
      This paper proposes a novel classifier based on the theory of Learning Automata (LA), reckoned to as PolyLA. The essence of our scheme is to search for a separator in the feature space by imposing an LA-based random walk ...
    • Smooth estimates of multiple quantiles in dynamically varying data streams 

      Hammer, Hugo Lewi; Yazidi, Anis (Pattern Analysis and Applications;Published online:09 April 2019, Journal article; Peer reviewed, 2019-04-09)
      In this paper, we investigate the problem of estimating multiple quantiles when samples are received online (data stream). We assume a dynamical system, i.e. the distribution of the samples from the data stream changes ...
    • Tracking of Multiple Quantiles in Dynamically Varying Data Streams 

      Hammer, Hugo Lewi; Yazidi, Anis; Rue, Håvard (Pattern Analysis and Applications;, Journal article; Peer reviewed, 2019-01-16)
      In this paper we consider the problem of tracking multiple quantiles of dynamicallyvarying data stream distributions. The method is based on making incremental updates ofthe quantile estimates every time ...
