Abstract

Banking and regulatory AML use advanced ML. This study shows ML algorithms may detect suspicious transaction patterns, improve compliance, and reduce AML framework false positives. Traditional AML systems struggle with scalability, monitoring new money laundering methods, and processing massive data quantities. Compliance fatigue and resource waste happened. ML significantly affects AML procedures. Benefits include abnormality detection, resource management, and reduced human monitoring. 

Superior supervised, unsupervised, and semi-supervised machine learning can detect complex money laundering. Using labelled datasets, decision trees, random forests, and SVMs can forecast risk. These work but money laundering tactics vary, therefore we need more. Hierarchical clustering and K-means are great unsupervised algorithms. Finding hidden pre-labeled data patterns. They spot irregularities other methods miss. Semi-supervised learning uses little labelled data and plenty of unlabelled data to increase model accuracy and performance. 

The RNN and LSTM excel with sequential data like transaction logs and time-series analysis. Models reveal modest money laundering as circumstances change. Deep learning algorithms respond to high-dimensional data with AML automation. The NLP evaluates transaction descriptions and communication channels. ML-based AML solutions are stronger because they can spot suspicious behaviour patterns that numbers cannot. 

Compliance officers dread AML ML false positives. Modern anomaly detection approaches and hybrid models with supervised and unsupervised learning may minimise false positives and increase detection rates. Ensemble learning enhances model accuracy and reliability. Transfer learning, which applies pre-trained models to AML tasks, may save training time and data, boosting model deployment. 

Linking AML machine learning data quality, privacy, and algorithmic openness is difficult. ML models need extensive, high-quality financial transaction, consumer, and fraud data. GDPR and other laws mandate data privacy and combination. Training credible models with insights needs data pretreatment, normalisation, and feature engineering. Explain ML model options to non-technical people to get acceptance. XAI-based LIME and SHAP explain model judgements. Lawfulness and transparency establish confidence. 

We study real-world cases and ML-based AML solutions. Case studies demonstrate how banks and other financial institutions have embraced machine learning (ML) and its pros and cons. Machine learning systems that are easy to set up and alter will be compared to financial companies' proprietary algorithms. Bitcoin and sophisticated shell corporations provide new cyber threats and money laundering methods, needing ML model enhancements. Model retraining and algorithmic design tweaks frequently cure faults and maintain system performance. 

The paper encourages bank-regulator-technology company collaboration. Data-sharing may assist stop money laundering despite privacy concerns. Safe multi-party computation (SMPC) and federated learning frameworks for cooperative training allow financial institutions to share data without exposing datasets.
