When considering evaluation metrics for classification models, is it possible for one metric to rule them all? Join us for a lively debate between Aric LaBarr, Associate Professor of Analytics at NC State's Institute for Advanced Analytics, and Robert Robison, Elder Research Senior Data Scientist.

During the debate Robert champions AUC’s comprehensive measure of model performance, while Aric advocates for a broader perspective, emphasizing the importance of business context in metric selection. Tune in as host Evan Wimpey moderates the discussion, and gain valuable insight on what really matters when it comes to machine learning model evaluation. We hope you enjoy the conversation!



In this episode you will learn:

⛛ The importance of exploring various metrics to evaluate model performance

⛛ Why metrics should align with business objectives

⛛ The need for data science teams to invest time in feature engineering

⛛ Why a model's success relies not only on its performance but also on stakeholders' ability to understand and trust the insights it provides

Quotes
💬 “There's a difference between communicating the value of a model and distinguishing between which models are better.” –Robert Robison

💬 “If you can't explain the model to your stakeholders or business users, then it's not going to get implemented.” –Aric LaBarr
