Description

With the recent proliferation of data in all aspects of the enterprise, the use of machine learning and predictive models have become pervasive across modern organizations. However, the real value of an AI system goes beyond data-driven predictions into full decision automation. Automating decisions in the wild requires careful consideration of implicit constraints and fuzzy business objectives to ensure that decisions are robust and consistent with the business goals.

This talk will focus on leveraging modern data-enabled machine learning methods and traditional operations research optimization techniques for decision automation in the context of retail enterprise applications. It will begin by reviewing the challenges of automating decisions ranging from specification of soft and hard constraints combined with fuzzy objectives. Borrowing techniques from other disciplines such as operations research and mathematical optimization, we will describe how we combined modern ML techniques with traditional operations research methods to solve two important problems in enterprise retail. The first problem details how we generate product recommendations that are consistent with business requirements such as contractual obligations, diversity and serendipity, and incremental sales. The second problem describes how we solve the inventory management problem that takes into account various supply chain constraints, while simultaneously leveraging data-driven ML techniques to optimize for overall financial impact. Finally, we describe some general strategies to ensure that data-driven predictions used in decision making are robust and consistent with business objectives and goals.

Prerequisite knowledge

Basic understanding of machine learning and mathematical optimization

What you'll learn

Automating decisions requires taking into account constraints and objectives that are not readily available using machine learning methods. Modern machine learning methods can be combined with traditional operations research optimization techniques to build a robust decision automation syste
