“…We follow the same approach as before by exploiting a generic graph structure defining the (regularized) matrixS that expresses geometric information as in (9). We would like to calculate the minimum bounding hypershere that encloses (most of) the training data representations in F, where a is the hypershere center and R the minimum radius.…”

“…Several surveys have been published detailing the different methods developed for anomaly detection [2][3][4][5]. For instance, Garcia-Teodoro et al [3] describe anomaly detection as "one-class classification" where the training data are used to build a model of "normal" data.…”

“…Em seguida, determina-se a confiabilidade da predição através de alguma técnica que busque inferir o quão semelhante o sinal de sonar analisado é em relação à classe escolhida. Esta segunda etapa é conhecida na literatura como detecção de novidades [3], sendo o foco deste artigo.A estrutura do artigo é detalhada a seguir. A Seção II apresenta a base de dados utilizada, contextualizado o problema.…”
