The study of how to program computers to exhibit intelligent behavior whether through problem solving, human computer interaction such as question answering, learning, solving optimization problems, or some combination of these. Areas of study include knowledge-based systems research, probabilistic reasoning and other forms of uncertainty handling, machine learning, neural networks and genetic algorithms. Common problems researched include those revolving around recognition/classification (such as speech recognition, visual comprehension, diagnosis, text mining) and planning/design.
Dr. Gary Newell studies problems involving Pattern Recognition with Uncertainty as well as exploring the boundaries of computation. For example, recent projects and publications have dealt with identifying Non-Recursively Enumerable Problems (i.e. highly undecidable problems), as well as Gestural Recognition using Probabilistic models. In particular, two recent publications have dealt with the extension of the INCA model which consistently surpasses existing recognition techniques in the area of pattern recognition with uncertainty. His recent research interests include examining the topic of Predictive Analytics as it might be applied to areas of Artificial Intelligence.
Dr. Kevin Kirby's dissertation and early research was in neural networks and genetic algorithms, with an emphasis on biologically realistic models. He spent a research summer at Wright Patterson Air Force base and, inspired by Alan Turing’s morphogenesis model and recurrent neural networks, developed what was later known as reservoir computation. He also created and taught workshops for Air Force scientists and engineers in the early 1990s on neural networks. He later branched out more broadly into natural computation, and published on quantum information in biological systems. He received the George Polya Award from the Mathematical Association of America for my exposition of neural associative memory in terms of the Dirac notation from quantum mechanics. Dr. Kirby's continuing long-term research interests include information geometry, Helmholtz machines, and deep learning, the latter now made more practical by GPU-accelerated computation.

Cybersecurity is the study of how to protect information, networks, and systems from threats ranging from cybercriminals to cyberespionage and cyberwarfare. Inventive attackers evolve new attacks every day, forcing defenders to continually innovate with new techniques to prevent, detect, and respond to cyberattacks. Simultaneously, engineers are creating new types of connected devices without thinking of security like the smart TVs, cars, and medical devices that make up the Internet of Things, creating new vulnerabilities in existing networks. Traditional perimeter and endpoint defenses like firewalls and anti-virus that were effective in the 1990s, no longer stop most attackers, pushing defenders to focus on adaptive security techniques based on threat intelligence and machine learning. NKU’s School of Computing and Analytics is home to a National Security Agency Center of Excellence in Cybersecurity. Several of the school's faculty are involved in different facets of cybersecurity research.
Dr. Yi Hu’s research concentrates on Cloud Security, Intrusion Detection, Penetration Testing, Vulnerability Assessment, Data Security, Data Mining, and Trust Management in Cyberspace.

From a computational perspective and utility perspective, data privacy sits at the boundary between data collection and data usage. It involves a balancing act where the goal is to change the data to the right degree so it does not leak private information when released to third parties, or publicly, while also preserving important information that the data carries. A broader interdisciplinary view of data privacy also includes the public expectation of privacy and the legal privacy regulations and associated issues. More about the data privacy research at NKU is online at http://cscdb.nku.edu/dataprivacy/
