Stochastic proximal splitting algorithm for composite minimization
Andrei Patrascu, Paul Irofti
Supported by the recent contributions in multiple branches, the first-order splitting algorithms became central for structured nonsmooth optimization. In the large-scale or noisy c…
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…
New nonasymptotic convergence rates of stochastic proximal pointalgorithm for convex optimization problems
Andrei Patrascu
Large sectors of the recent optimization literature focused in the last decade on the development of optimal stochastic first order schemes for constrained convex models under prog…
