Rexer Analytics - Thought Leadership

Data Science Surveys

Rexer Analytics has been conducting the Data Miner Survey since 2007. In 2015 we re-branded it as the Data Science Survey. This research program examines the analytic behaviors, views and preferences of data analytic professionals. More information about the Data Science Surveys and the summary report download links are available HERE.

"I consider Rexer Analytics’ surveys one of the best independent analyses of Data Mining. I stress the word ‘independent’ as that is the most useful. Karl and his team have been active in this market for many years and bring considerable experience to the topic."

– John MacGregor, Vice President, Customer Innovation & Strategic Projects, Products & Innovation, SAP; Author of “Predictive Analysis with SAP: The Comprehensive Guide”

"Rexer Analytics has been instrumental in helping advance the field of data mining through applied research, software evaluation, testing, professional conference support and consulting. Their research evaluating the trends and preferences among the data mining community is a great resource for many."

– Wayne Thompson, PhD; Chief Data Scientist, SAS

"The Rexer Analytics Data Mining Survey provides valuable insight into trends in tools and techniques, as well as backgrounds of data mining practitioners. Rexer's analysis of the survey data dives into hype or reality of big data to the rise of analytics software like R, as well as challenges faced by analysts and their job satisfaction. I look forward to each survey's results and increasingly see these results highlighted in presentations from other well-respected experts in the field."

– Mark Hornick, Director, Oracle Advanced Analytics, Oracle Corporation; Author of “Using R to Unlock the Value of Big Data: Big Data Analytics with Oracle R Enterprise and Oracle R Connector for Hadoop”

"The Data Science Survey is one of the few unbiased resources that provides a comprehensive overview of the data science community. It is a key source of information for analytic professionals regarding vendors, tools, and state-of-the-art algorithms. As a frequently cited publication, it covers essential topics, new trends like “big data”, as a well as general market surveillance."

– Michael Zeller, PhD; CEO, Zementis

"The Rexer Analytics Data Miner Survey is the best survey of the current state and direction of the data mining and predictive analytics industry. I recommend it to my workshop and course attendees regularly as a way to understand the important trends in software, algorithms, job titles, and vertical markets, as well as issues impacting the analytics industry and which buzz words are gaining traction."

– Dean Abbott; Co-Founder & Chief Data Scientist, SmarterHQ; Founder & President, Abbott Analytics; Author of “Applied Predictive Analytics: Principles and Techniques for the Professional Data Analyst” and “IBM SPSS Modeler Cookbook”

Karl Rexer was among the Data Science leaders speaking at the Oct. 2017 New York Predictive Analytic World conference. Karl gave two presentations and moderated sessions in both the Business track and the Financial Services track.

Karl Rexer was one of four industry leaders at the 2017 Oracle BIWA Summit selected to be interviewed on theCUBE. TheCUBE is the flagship show of SiliconANGLE Media and a leading live interview show covering enterprise technology and innovation.

"Rexer Analytics is definitely one of the key players in the Data Mining ecosystem. I was introduced to the world of data science when I attended Karl’s Hands-on Lab at the 2008 Oracle BIWA Summit. In addition to the software training, Karl spent extra time with me, answering questions and providing implementation advice. Karl is one of the organizers of the annual BIWA Summit, and it is an outstanding event. Each time I bring my analytic team. We look forward to talking with Karl and others, sharing our successes, discussing ways to overcome challenges, and learning new things. Karl’s original Oracle Data Miner training session got us started -- and in the subsequent years our Risk Analytics team has tackled tough business challenges, and been very successful in fighting e-payments fraud. Rexer Analytics is the go-to team to help create analytic solutions."

– Julia Minkowski; Risk Analytics Manager, Fiserv; and Co-founder, “Russian Speaking Women in Tech”

"Karl has generously dedicated a great amount of time and energy to helping my students succeed – by being a frequent guest speaker in undergraduate and MBA business analytics classes, by serving on the industry advisory board that helped shape Babson’s undergraduate and MBA business analytics concentrations, and by advising individual students on careers in data science and business analytics. The depth and breadth of his experience and knowledge are evident, and have been helpful to both students and faculty at Babson."

"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."
