A two-armed bandit collective for examplar based mining of frequent itemsets with applications to intrusion detection
Haugland, Vegard; Kjølleberg, Marius; Larsen, Svein-Erik; Granmo, Ole-Christoffer (Lecture Notes in Computer Science;6922, Chapter; Peer reviewed, 2011)Over the last decades, frequent itemset mining has become a major area of research, with applications including indexing and similarity search, as well as mining of data streams, web, and software bugs. Although several ... -
A two-armed bandit collective for hierarchical examplar based mining of frequent itemsets with applications to intrusion detection
Haugland, Vegard; Kjølleberg, Marius; Larsen, Svein-Erik; Granmo, Ole-Christoffer (Lecture Notes in Computer Science;8615, Chapter; Peer reviewed, 2014)In this paper we address the above problem by posing frequent item-set mining as a collection of interrelated two-armed bandit problems. We seek to find itemsets that frequently appear as subsets in a stream of itemsets, ... -
Anomaly detection in computer networks using hierarchically organized teams of learning automata
Haugland, Vegard; Kjølleberg, Marius; Larsen, Svein-Erik (Master thesis, 2011)With the increasing number of computer systems connected to the Internet, security becomes a critical issue. To combat this problem, several attack detection methods have emerged in the past years, such as the rule based ...
