• Abstract: Money laundering enables organized crime by allowing illicit funds to enter the legitimate economy. Although trillions of dollars are laundered each year, only a small fraction is ever uncovered. This stems from a range of factors, including deliberate evasion by launderers, the rarity of confirmed cases, and the limited visibility each financial institution has into the global transaction network. While several synthetic datasets are available, they fail to model the structural and behavioral complexity of real-world money laundering. In particular, they often overlook partial observability, sparse and uncertain labels, strategic behavior, temporal dynamics, class imbalance, and network-level dependencies. To address these limitations, we present AMLGentex, an open-source suite for generating realistic, configurable transaction data and benchmarking detection methods. It enables systematic evaluation of anti-money laundering (AML) systems in a controlled environment that captures key real-world challenges. We demonstrate how the framework can be used to rigorously evaluate methods under conditions that reflect the complexity of practical AML scenarios.

  Blind source separation (BSS) aims to recover an unobserved signal from its mixture $X=f(S)$ under the condition that the transformation $f$ is invertible but unknown. We present a general framework for analysing such violations and quantifying their impact on the blind recovery of $S$ from $X$. We show that a generic BSS-solution in response to general deviations from its defining structural assumptions can be profitably analysed in the form of explicit continuity guarantees.

  Money laundering is a process where criminals use financial services to move illegal money to untraceable destinations.
