“…An ONION employs an offline preprocessing phase followed by an online exploration phase, enabling users to establish connections among outliers. As it is difficult to set appropriate D and k values [70,71], the offline phase is a preprocessing three-dimensional phase that computes all possible combinations of D, k, and entire dataset instances. In fact, k can take in the universe of natural numbers and the user must specify lower and upper bounds for k. This phase outputs all outlier candidates.…”

“…Kontaki et al [37], existem poucos trabalhos de pesquisa que estudam o problema da detecção de anomalia em fluxo de dados, tais como [19], [32], [37]- [39]. No entanto, nestes trabalhos, os algoritmos ou técnicas não foram projetados para serem executados em dispositivos cujo poder de processamento e memória são limitados.…”
