  • Ellis, Mathys (University of Pretoria, 2020)
    Streamed data classification problems (SDCPs) require classifiers with the ability to learn and to adjust to the underlying relationships in data streams, in real-time. This requirement poses a challenge to classifiers, ...
  • Van der Stockt, Stefan Aloysius Gert (University of Pretoria, 2019)
    Dynamic optimization problems provide a challenge in that optima have to be tracked as the environment changes. The complexity of a dynamic optimization problem is determined by the severity and frequency of changes, as ...
  • Singh, Avinash (University of Pretoria, 2019)
