Software Engineering for Machine Learning

November 2021 Podcast
Grace Lewis, Ipek Ozkaya

Grace Lewis and Ipek Ozkaya discuss their research into software engineering for machine learning (ML) with host Jonathan Spring.

“Machine-learning systems are built by three different types of teams. You have data scientists or machine-learning engineers that are building machine-learning models. Then that model is passed to a software engineering team for integration into a larger system, and then the system is passed to an operations team in charge of operating and monitoring the system as a whole. Because these teams operate independently, they tend to make assumptions about what the other teams are doing, leading to mismatch. Mismatch occurs because of an incorrect assumption made in isolation by one of these teams.”

Abstract

Mismatches between the perspectives and practices of the roles involved in the development and fielding of ML systems—data scientists, software engineers, and operations personnel—can affect the ability of systems to achieve their intended missions. In this SEI Podcast, Grace Lewis, a principal researcher and lead for the Tactical and AI-Enabled Systems Initiative, and Ipek Ozkaya, technical director of Engineering Intelligent Software Systems, discuss their research into characterizing, codifying, and mitigating such mismatches.
