Paul Gader

Paul Gader (Ph.D. Mathematics, 1986) is Professor & former Chair of Computer and Information Science and Engineering & an affiliate Professor in Environmental Engineering Science at the University of Florida. He was a Senior Research Scientist at Honeywell’s System & Research Center; Research Engineer & Manager at the Environmental Research Institute of Michigan; and a professor at Universities of Wisconsin-Oshkosh (Math), Missouri (Electrical and Computer Engineering) and Florida.  He was a Visiting Professor of Signal Processing at Grenoble Institute of Technology, France & Geography & Comp. Sci. at UC – Santa Barbara.

During his 34 year research career, his activities have ranged from mathematical theory to fielded, operational algorithms for machine learning using data acquired from sensors. He has been a leading researcher of algorithms for handwriting recognition & landmine detection and has worked on a number of other problems, some of which are highlighted here.

His PhD research focused on deriving matrix factorization mathematical programming algorithms for mapping global transformations to locally connected, parallel architectures. He derived decompositions of Fourier & General Linear as well as Nonlinear Morphological Transforms of any size into a sequence requiring only local information. In the early 1990s, he led the development of a 5th ranked neural network handwritten character recognizer and a top ranked handwritten word recognizer in a NIST competition. In the late 1990s, he led teams that devised and implemented Hidden Markov Model and Possibilistic detectors in real-time on a Mine Detection System fielded in Afghanistan in 2008.  The system is featured in a National Geographic Television program: “Bomb Hunters: Afghanistan”.

He has been researching hyperspectral image analysis, a.k.a. imaging spectroscopy, algorithms since 2002 for agriculture, the environment, and national security.  His team collected VNIR LiDAR airborne data and built ground truth.  He has studied a variety of research activities in unmixing (an inverse-problem), dimensionality reduction, and classification using NASA and NSF big data sets and investigated hyperspectral and color imaging for ripeness, disease, landmines, and explosives detection.  He is developing physics-based, data-driven nonlinear, and hybrid computational models for hyperspectral unmixing.  He was general chair of the IEEE Workshop on Hyperspectral Image and Signal Processing (WHISPERS) in June 2013.  He gave tutorials on sub-pixel analysis (unmixing) at WHISPERS in 2016 and 2018.  He is also conducting research into understanding fish behavior using underwater acoustics and video.  The research involves segmenting and identifying sounds and identifying fish using spatial-temporal tracking.

He has worked with neural networks since 1990. He is researching a general problem, which is the inability of deep networks to behave in a stable, predictable way when presented with samples from unknown distributions.  This is sometimes referred to as competency-aware machine learning.

Dr. Gader has published over 100 journal and over 300 total papers, served for three years as a UF Research Foundation Professor and was named an IEEE Fellow in 2011.

In his free time, he plays saxophone in a big-band and a small jazz group and enjoys hiking in and observing nature.
