recommendations! Published in 2024 at "Neural Processing Letters"

DOI: 10.1007/s11063-024-11623-y

Abstract: Fuzzy cognitive maps (FCMs) provide a rapid and efficient approach for system modeling and simulation. The literature demonstrates numerous successful applications of FCMs in identifying failure modes. The standard process of failure mode identification using… read more here.

DOI: 10.3233/thc-236049

Abstract: BACKGROUND: The wrist pulse wave under the optimal pulse pressure plays an important role in detecting human body’s physiological and pathological information. Wavelet threshold filtering is a common method for pulse wave de-noising. However, traditional… read more here.
