Complexity of Inexact Proximal Point Algorithm for minimizing convex functions with Holderian Growth
Andrei Pătraşcu, Paul Irofti
Several decades ago the Proximal Point Algorithm (PPA) started to gain a long-lasting attraction for both abstract operator theory and numerical optimization communities. Even in m…
Stochastic Proximal Gradient Algorithm with Minibatches. Application to Large Scale Learning Models
Andrei Patrascu, Ciprian Paduraru, Paul Irofti
Stochastic optimization lies at the core of most statistical learning models. The recent great development of stochastic algorithmic tools focused significantly onto proximal gradi…
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…
