“…Moreover, it advances collaborative filtering predictions using decision-making and a convolutional neural network (CNN) for the classification of unstructured life care contexts. The eleventh paper by Kumar and Kamalraj (2019) proposes an ambient-intelligence architecture using a modified square root carry-select adder and a modified Russian peasant multiplier. The study aims to construct a half-band filter with a cascade structure for biomedical contexts, such as electroencephalograms (EEGs), electrocardiograms (ECGs), etc.…”
