    Abstract : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. READ MORE

  3. 3. Securing Information Assets Understanding, Measuring and Protecting against Social Engineering Attacks

    University dissertation from Stockholm University

    Author : Marcus Nohlberg; Högskolan i Skövde.; Högskolan i Skövde.; Stockholms universitet.; [2008]
