Doug Levin of Quant5 presented on how to apply predictive analytics to marketing challenges. He outlined challenges facing marketing departments like making decisions without insights and a lack of data scientists. Levin discussed gathering different types of customer and transactional data to determine key metrics like product relationships, customer scores, and targeted promotional offers. He emphasized using machine learning algorithms and predictive modeling rather than spreadsheets to glean non-obvious insights from data. Levin demonstrated these concepts using a sample ecommerce company called Lucy Couture.
