“…This drawback can be mainly ascribed to the binary coding of the ART algorithm as it is a less flexible way of using process data than a method based on graded continuous number encoding. In fact, subsequent researches extended this methodology and presented outperforming ART neural networks for unnatural behavior detection (Pacella & Semeraro, 2005;Pacella, Semeraro, & Anglani, 2004a, 2004b. In particular, a simplified Fuzzy ART algorithm, which incorporates computations from fuzzy set theory by which can categorize analog patterns, was presented.…”
