Lior Rokach is a data scientist and a Full Professor of Information Systems and Software Engineering. He currently serves as the chair of the Department of Software and Information System Engineering at the Ben-Gurion University of the Negev. His research interests lie in the areas of Data Science, Machine Learning, Big Data, Deep Learning and Data Mining and their applications to:
- Recommender Systems
- Cyber Security
- Information Retrieval
- Information Extraction
- Scientometrics
- Medical Informatics
Prof. Rokach received a B.Sc. (summa cum laude, 1998), M.Sc. (cum laude, 1999) and PhD (2004) from Tel Aviv University. Since 2005 he has been a faculty member at Ben-Gurion University. In addition, he has had several visiting positions - the most recent at the College of Information Sciences and Technology at the Pennsylvania State University, University Park, PA.
Prof. Rokach is the author of over 300 peer reviewed papers in leading journals
(e.g., Machine Learning, Machine Learning Research, Data Mining and Knowledge Discovery, IEEE Transactions on Knowledge, and
Data Engineering and Pattern Recognition), conference proceedings, patents, and book chapters.
Rokach has authored several popular books in data science, including Data Mining with Decision Trees (1st edition, World Scientific Publishing, 2007, 2nd edition, World Scientific Publishing, 2015). He is also the editor of "The Data Mining and Knowledge Discovery Handbook" (1st edition, Springer, 2005; 2nd edition, 2010) and "Recommender Systems Handbook" (1st edition, Springer, 2011; 2nd edition, 2015).
His works are highly cited and his books are standard classroom reading on the topic for graduate courses. Several excellent scholarly book reviews regarding Prof. Rokach's monographs have been published, to name a few:
''It is a timely publication, ... The book is a comprehensive and detailed reference book ... It could be very useful to graduate students who wish to broaden their knowledge in the area or are doing a project in this or a related area. It could also be useful to practitioners who wish to use decision trees in their day-to-day data mining work'' Mark Levene, The Computer Journal, Oxford University Press, 2008
''The book presents an interesting and pleasant introduction to the topic, which can guide the reader to the knowledge of the existing decomposition methods, and to the choice of those most promising for the problems he has to face." Zentralblatt MATH, 2007
''Here they give students and professionals what they need to grow decision trees, evaluate classification trees, split criteria, "prune" trees, create advanced decision trees and forests, manage incremental learning of decisions trees, select features, make fuzzy trees, combine decision trees with other techniques and classify sequences. Their text is accessible and loaded with examples, and their bibliography is especially comprehensive.'' SciTech Book News, 2008
''... the book is a very useful and nice coverage of the field ... It is highly recommendable for people who want to begin working in this field and need guidance to start into the large area of applying these methods.'' Zentralblatt MATH, 2008.
''...This handbook provides an excellent guide in every aspect of the discovery process... This new edition again serves to define the current state of the art in knowledge discovery ... It is an indispensable reference for researchers and an excellent starting point for advanced students taking graduate courses in this area. Summing Up: Highly recommended ''(Cheung, J Y, Data mining and knowledge discovery handbook. Choice, 48(10), 1953-1953, June, 2011)
''...I recommend this comprehensive book to advanced readers--including designers and architects at software companies--interested in the R&D of data mining.'' (K. Balogh, ACM Computing Reviews, November, 2011)
''... The model is not only able to predict and explain a phenomenon in the datasets; it also utilizes a problem's domain knowledge to suggest specific actions for achieving optimal changes in the values of the target attributes ... The book is very well written, easy to understand, and easy to follow. Each chapter is well organized.'' (Xiannong Meng, ACM Computing Reviews, October, 2014)
Prof. Rokach is currently serving as an area editor for Information Fusion (published by Elsevier). He has recently served as a Guest-Editor in Information Sciences (published by Elsevier) for a Special Issue titled ''Data Mining for Information Security''. He regularly serves on related conference program committees (such as ACM RecSys, ACM KDD, and ACM CIKM) and has helped organize several sessions. He has given several invited and keynote talks. He regularly serves as a referee for many international journals, research proposals, books proposals, and PhD committees.
Prof. Rokach established the Machine Learning Research Laboratory at BGU which hosts graduate students working in a lab during the academic year. The lab carries out research and projects in the broad area of machine learning and its applications, and specifically, the lab promotes innovative adaptations of machine learning methods to create the next generation of Intelligent Systems. Since its establishment in March 2006, the machine learning lab has been involved in more than fifty research projects that attracted a significant amount of funding.
Among the institutions that have funded Prof. Rokach's research are: Deutche Telekom Co., DARPA, Intel, IBM, Audi, EMC, Lockheed Martin, General Motors, the Israeli Ministry of Science, the Israeli Ministry of Defense (Center for Development of Means and Infrastructure), Israeli Ministry of Trade and Commerce.
His current research interests include:
Prof. Rokach has made core contributions to the field of machine learning by developing novel ensemble learning algorithms. He has been involved in the creation and development of various novel recommender systems which are deployed in real large scale e-commerce web-sites serving millions of users. Dr. Rokach has highly contributed to the field of Information Security by developing machine learning algorithms that are capable of identifying malwares and protecting user data and privacy. He is the awardee of the 2012 BGU Toronto Prize for young researchers. His research has been highlighted in many places including the
BBC Radio, CBS News, The Telegraph, Internet World, Israel Channel 2, Reshet Bet (Israel Leading National News Radio Station), and Galei Tzahal (the official Israel Defense Forces Radio), Yedioth Ahronoth (Israel's largest daily newspaper), Haaretz (Israel's oldest daily newspaper), The Jerusalem Post, Calcalist, Globes and The Marker (daily financial newspapers).
Prof. Rokach is an excellent educator who takes special interest in inspiring students. He has supervised more than 60 graduate students at all levels, from master degrees to post-docs. The majority of his students received honorable recognition through their research presentation from universities all over the globe. Prof. Rokach co-established the MSc program in Data Mining and Business Intelligence. Graduates of this program acquire a variety of skills required for integrating cutting edge information technologies with data analytics methods. The program offers a unique mix of courses in IT, in statistics and in machine learning. He was involved in the development of two courses for the Israeli Open University and has won six awards for excellence in teaching from three different institutes.
Prof. Rokach is an active entrepreneur with several patents and technology licenses. Prior to Ben-Gurion University, Prof. Rokach was involved for more than 15 years in information technology development and design.
