About Us
The Laboratory for Knowledge Discovery in Databases (KDD) is a research group in the Computing and
Information Sciences (CIS) Department at Kansas State University. Its research emphasis is in the areas
of applied artificial intelligence (AI) and knowledge-based software engineering (KBSE) for decision
support systems.
More specifically, we are interested in machine learning, data mining and knowledge discovery from large
spatial and temporal databases, human-computer intelligent interaction (HCII), and high-performance
computation in learning and optimization. In our research, we look for ways to systematically decompose
analytical learning problems based upon information theoretic and probabilistic criteria, so that the most
appropriate machine learning methods may be applied to the resulting transformed problems.
One of the major challenges in this area is the design of unsupervised learning and bias (or hyperparameter)
optimization methods to produce an effective decomposition of learning tasks. An interesting opportunity
presented by this problem is that, by addressing the high-level control of inductive learning in a
statistically sound fashion, we can improve our techniques for both model selection and model integration
(as practiced in multimodal sensor fusion). We have developed and applied such approaches to multistrategy
learning, which are potentially computation-intensive, to interesting analytical problems in the areas of
decision support (uncertain reasoning) and control automation.
The goal of our work is to gain insight into the interaction between artifacts that adapt or learn -
whether by Bayesian, neural, or genetic computation - and their users. Important examples of this
interaction include data visualization in intelligent displays, software agents for distributed
high-performance computation and information retrieval, and virtual environments for simulation and
computer-assisted instruction.
