Anomaly Detection through Isolation Forest, Dictionary Learning and One Class SVM with applications
in computer networks
Abstract: The first part of the presentation will introduce Isolation Forest based anomaly
detection models, their characteristics and scope. The initial Isolation Forest, its limitations
and a few variants that seek to improve detection performance while keeping the low execution
time will be presented. The second part will show the contributions that I had in the NetAlert
project, focusing on the implementation of some AD models tailored for the detection of some
specific attacks. The last part will specify my contribution on the implementation of some
anomaly detection models based on Dictionary Learning and OCSVM.
