In this talk we will provide an overview of business analytics and data science applications. Analytics is the scientific process of deriving insights from data in order to make decisions. With the help of analytics, companies and individuals can uncover insights more quickly and more easily from all types of data — even big data. We briefly overview algorithms and techniques for data analysis including statistics, simulation modeling, data mining, optimization and cognitive computing. We use examples and case studies to illustrate practical applications of business analytics in finance, risk management, health care, smart city projects, crime prevention, predictive maintenance, marketing, sustainable development, web and social media analytics, personal analytics, etc. Business analytics and data science allow hundreds of companies and governments to save lives and minimize resource usage. We would try to understand how Ukraine and other countries can take advantage of analytics.
