Predictive Data Science
3 Days Instructor-led
Predictive analytics is a branch of statistics and data analysis that uses data modeling and artificial intelligence to predict the future outcomes of decisions, events, and trends. By identifying trends and patterns in data and understanding data relationships, data analysts can build models to forecast the effects of different strategies, help solve business problems, and aid in decision-making.
Predictive analytics can be applied in industries ranging from financial services to healthcare, to retail. This 3-day course will teach you everything you need to know about predictive analytics so you and your organization can benefit from this cutting-edge technology. Learning predictive analytics may feel challenging because it requires mastering a range of skills, including statistics, programming languages, and other tools. It can take time to understand when to apply particular predictive analytics techniques and how to quantify success for problem-solving on projects without clearly defined answers. This course will help you fill in all the details.
Course Outline
1. Problem Definition and Project Management
- Determine whether a problem should be addressed with predictive analytics or traditional analysis techniques
