Fuzzy Clustering of Parallel Data Streams

Abstract: The management and processing of so-called data streams has recently become a topic of active research in several fields of computer science, notably database systems and data mining. A data stream can roughly be thought of as a transient, continuously increasing sequence of time-stamped data. In this paper, we consider the problem of clustering parallel streams of real-valued data, that is to say, continuously evolving time series. More specifically, we are interested in grouping data streams the evolution ov… Show more

“…Medidas de similaridade entre agrupamentos também são usadas para agrupamento consensual (consensus clustering), avaliação da estabilidade de agrupamento e até para a quantificação da perda de informação (Strehl e Ghosh, 2003;Monti et al, 2003;Yu et al, 2007;Beringer e Hüllermeier, 2007;). Técnicas de agrupamento consensual objetivam encontrar soluções de alta qualidade combinando várias soluções obtidas por diferentes métodos, inicializações do algoritmo ou perturbações da mesma base de dados.…”

“…Uma outra aplicação interessante para medidas de similaridade consiste na quantificação da perda de informação (Beringer e Hüllermeier, 2007). Para melhorar a efetividade de uma técnica de agrupamento (e.g., no contexto de agrupamento em fluxo de dados), pode-se mapear os dados em um espaço de menor dimensionalidade e só então realizar o agrupamento dos dados.…”
