"The Rexer Analytics team has a passion for data mining. This is illustrated by their outstanding Data Miner Survey research, and the contributions of time and expertise they make to professional organizations and conferences. I first met Karl when we both served on the KDD-2006 conference organizing committee. He has worked on a number of international data mining conferences, and been instrumental in soliciting sponsors, reviewing papers, judging best paper prizes, and teaching hands-on labs. I have been involved with INFORMS for many years, and was happy to see Karl jump at my offer to participate. He spoke at a local INFORMS chapter, encouraged others to attend INFORMS conferences, and he and his team wrote an article for the INFORMS ‘Analytics Magazine.’ My data scientist colleagues and I applaud the contributions of Rexer Analytics."
