Big Data  Big data is an all-encompassing term for any collection of data sets so large and complex that it becomes difficult to process using traditional data processing applications.  Big data is being generated by everything around us at all times. Every digital process and social media exchange produces it. Systems, sensors and mobile devices transmit it. Big data is arriving from multiple sources at an alarming velocity, volume and variety. To extract meaningful value from big data, you need optimal processing power, analytics capabilities and skills.  84% Of Enterprises See Big Data Analytics Changing Their Industries' Competitive Landscapes In The Next Year 84% Of Enterprises See Big Data Analytics Changing Their Industries' Competitive Landscapes In The Next Year

Networks: theory and application This course will introduce the modern network theory and its numerous applications ranging from online social and mobile communication networks to search, marketing, fraud detection, epidemiology and dynamic processes on networks such as spread of information, opinions and behaviors. The objective is to learn to recognize and deal with the phenomena characteristic to the highly interconnected environments we and our businesses inhabit today. We will cover subjects like network classification, random graph models, network motifs, community structure, resilience of networks to disruption and social network – specific concepts such as word- of-mouth, structural holes, peer effects, homophily and information cascades. Emphasis will be made on practical application of the learned material and in particular network data collection, its analysis and interpretation.

Social Aspects of Socio-technical Systems It is still early to grasp the extent to which the recent surge of communication and data management technologies will eventually affect the way individuals, businesses and societies operate. But the change is already profound enough to review the variety of phenomena it inspired. This course will discuss socio-technical systems from social and business perspectives and develop the skills necessary to model and analyze them. We will discuss various forms of collective behavior, wisdom of crowds, public opinion formation, information markets, social media, emergence of the computational social science and implications of availability of huge amounts of social data (i.e. privacy, personalization, etc.). We will gain experience in empirical analysis of such systems and their modelling using analytical and computational tools, learn causal inference techniques and agent-based modelling.
