  • 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)
    Article
    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)
    Article
