In an era when misinformation spreads faster than ever, cutting-edge statistical and machine learning techniques offer a powerful defense. This book provides a rigorous, technical deep dive into misinformation detection, combining statistical modeling, signal processing, and machine learning to tackle false information across digital media.

Beginning with an overview of the role of statistics in detecting misinformation, the book explores latent variable models, independent vector analysis, semi-supervised learning, and multimodal fusion. In that way, the book offers advanced yet practical methodologies for real-world applications.

A dedicated section on system integration and deployment focuses on how these techniques can move beyond theory into actionable solutions, covering explainability, evaluation, and human-in-the-loop aspects. The book also critically examines the social, ethical, and financial implications of misinformation, and provides insights into policy challenges and freedom of expression concerns.

Roberto Corizzo is an Associate Professor in the Department of Computer Science at American University. He develops efficient and adaptive machine learning methods that continuously learn from evolving data while remaining reliable in high-stakes applications. His research focuses on continual learning, forecasting, anomaly detection, explainable AI, and class-imbalanced problems, with applications in finance, medical healthcare, cybersecurity, social networks, astrophysics, environmental monitoring, and scientific discovery. He co-authored over 85 articles, including 30 publications in international journals such as IEEE Transactions on Neural Networks and Learning Systems, Neural Networks, and Machine Learning, and international conferences such as AAAI, ICDM, ECML/PKDD, and ECAI. He is an Associate Editor for international journals including Machine Learning Journal of Big Data and International Journal of Data Science and Analytics. He served as Area Chair for the ECML/PKDD conference and on the program committees of international conferences such as ICML, AAAI, KDD, NeurIPS, and ICDM, and reviewed for several international journals.

Zois Boukouvalas is an Associate Professor in the Department of Mathematics and Statistics at American University, where he serves as Director of the M.S. programs in Data Science and Artificial Intelligence. He earned his Ph.D. in Applied Mathematics from the University of Maryland, Baltimore County (UMBC) in 2017 under the guidance of Dr. Tülay Adali.

His research focuses on developing reliable and responsible artificial intelligence, with particular emphasis on multimodal machine learning, trustworthy AI, and rigorous evaluation of AI systems. His work explores how information from multiple data sources and modalities can be integrated to build AI systems that are not only accurate, but also reliable, interpretable, and appropriate for real-world use.

His research spans applications in scientific discovery, natural language processing, biomedical data, chemistry, and materials science, including the use of AI to accelerate the discovery and characterization of novel materials. More broadly, his work seeks to bridge advances in machine learning with complex scientific and societal problems while addressing questions of reliability, transparency, robustness, and responsible deployment.
