Prioritization of public services for digitalization using fuzzy Z-AHP and fuzzy Z-WASPAS Complex Intell. Syst. (IF 3.791) Pub Date : 2021-01-03 Duygu Sergi, Irem Ucal Sari
In this paper, public services are analyzed for implementations of Industry 4.0 tools to satisfy citizen expectations. To be able to prioritize public services for digitalization, fuzzy Z-AHP and fuzzy Z-WASPAS are used in the analysis. The decision criteria are determined as reduced cost, fast response, ease of accessibility, reduced service times, increase in the available information and increased

A Hybrid Swarm and Gravitation-based feature selection algorithm for handwritten Indic script classification problem Complex Intell. Syst. (IF 3.791) Pub Date : 2021-01-03 Ritam Guha, Manosij Ghosh, Pawan Kumar Singh, Ram Sarkar, Mita Nasipuri
In any multi-script environment, handwritten script classification is an unavoidable pre-requisite before the document images are fed to their respective Optical Character Recognition (OCR) engines. Over the years, this complex pattern classification problem has been solved by researchers proposing various feature vectors mostly having large dimensions, thereby increasing the computation complexity
