Krzysztof Dzieciolowski, PhD
Part-time Faculty, Supply Chain and Business Technology Management
Industry Advisory Board to Data Science Research Centre, Computer Science and Software Engineering
Dr. Dzieciolowski’s career combines 20 years in data science leadership roles in the Canadian telecommunication industry with teaching and research, as a part-time faculty member at John Molson School of Business in Montreal.
He currently leads a Modeling and Analytics group in Rogers Communications where he develops predictive models and analytical solutions in key business areas of managing the business value, customer retention, revenue growth and acquisition of new customers.
At JMSB, Dr. Dzieciolowski teaches courses in data mining,statistics and analytical software to undergraduate and graduate students. He has built synergies between industry and academia and funded scholarships for students of Montreal universities. He has been instrumental in launching in 2016 a joint Certification in Business Analytics between JMSB and SAS – the world’s leader in data science software.
Dr. Dzieciolowski’s research interests focus on statistics and data science methods; in particular, on big data, predictive models, multivariate analysis, forecasting, econometric models, social networks and text analytics.In 2016 he obtained CUPFA Special JMSB Research award for the project in big data.
He obtained master’s degree in mathematics from Warsaw University in Poland and PhD in statistics from Queen’s University in Kingston,Ontario.
He is an active promoter of data science and a frequent speaker at academic and professional gatherings.
Statistical Software for Data Management and Analysis
The objective of the course is to gain a basic understanding of the concepts, principles and techniques of data management and statistical analyses through the use of Statistical Software. The focus of this course is on practical aspects of data management and statistical analysis with the help of Statistical Analysis System (SAS) – widely used by business, government and academia. In the process of familiarizing with SAS, principal attention will be given to data management techniques related to handing of data storage, information retrieval, variable and row transformation,data cleansing, file handling and preparation of data for analytics, visualization,statistical analysis and reporting. The course helps students understand methods of handling big data through the use of principles of efficient programming.Through hands-on approaches students learn how to design and execute programs for the data-intensive processes.
Data Mining Techniques
The objective of the course is to introduce basic concepts and techniques of Data Mining and its applications in business. In the recent years Data Mining, often also referred to as Data Science has become one of the most dynamically growing areas of business knowledge discovery field. Proliferation of computing resources, Internet, social networks, mobile communication with the resulting deluge of data, often called -Big Data, has motivated companies to turn data into an asset for decision making and used gain competitive advantage.
The course focuses on supervised and unsupervised data mining methods, their underlying principles and applications for structured data as well for unstructured data such as text.The data mining techniques introduced throughout the course include regression models and learning algorithms such as k-nearest neighbors, naïve Bayes,classification and regression trees, support vector machine, neural networks,discriminant analysis, association rules, cluster analysis and text mining.
