Description:

Join us for a presentation and discussion on new research led by Daniel Martin, Associate Professor of Managerial Economics & Decision Sciences at Kellogg.

Analyzing Machine Learning using Cognitive Economic Methods

In this line of research, we analyze machine learning predictions using cognitive economic methods.  We first propose three counter-factual optimality conditions on algorithmic performance and then evaluate these conditions using an experiment that involves training a convolutional neural network to predict pneumonia from chest X-rays.  We then show that these three optimality conditions imply two possible models of machine learning: feasibility-based and cost-based.  We find that the pneumonia detection algorithm's behavior aligns with our cost-based model of machine learning, enabling us to estimate the algorithm's associated learning costs using tools of cognitive economics.
