  • Data-based fault detection in chemical processes: Managing records with operator intervention and uncertain labels 

    Askarian, Mahdieh; Benítez Iglesias, Raúl; Graells Sobré, Moisès; Zarghami, Reza (2016-06-23)
    Open Access
    Developing data-driven fault detection systems for chemical plants requires managing uncertain data labels and dynamic attributes due to operator-process interactions. Mislabeled data is a known problem in computer science ...
  • Fault diagnosis of chemical processes with incomplete observations: A comparative study 

    Askarian, Mahdieh; Escudero Bakx, Gerard; Graells Sobré, Moisès; Zarghami, Reza; Jalali Farahani, Farhang; Mostoufi, Navid (Pergamon Press, 2016-01-04)
    Open Access
    An important problem to be addressed by diagnostic systems in industrial applications is the estimation of faults with incomplete observations. This work discusses different approaches for handling missing data, and ...
