Atom dimension adaptation for infinite set dictionary learning
Andra Băltoiu, Denis C. Ilie-Ablachim, Bogdan Dumitrescu
Recent work on dictionary learning with set-atoms has shown benefits in anomaly detection. Instead of viewing an atom as a single vector, these methods allow building sparse repres…
Unsupervised Dictionary Learning for Anomaly Detection
Paul Irofti, Andra Băltoiu
We investigate the possibilities of employing dictionary learning to address the requirements of most anomaly detection applications, such as absence of supervision, online formula…
Community-Level Anomaly Detection for Anti-Money Laundering
Andra Baltoiu, Andrei Patrascu, Paul Irofti
Anomaly detection in networks often boils down to identifying an underlying graph structure on which the abnormal occurrence rests on. Financial fraud schemes are one such example,…
Quick survey of graph-based fraud detection methods
Paul Irofti, Andrei Patrascu, Andra Baltoiu
In general, anomaly detection is the problem of distinguishing between normal data samples with well defined patterns or signatures and those that do not conform to the expected pr…
