Talk: Replicability in Machine Learning

LIVE STREAM: https://uwmadison.zoom.us/j/91073721984?pwd=blQzTWc5OEQvZ3pYUnFjQm8vRmVTUT09

Abstract: Replicability is vital to ensuring scientific conclusions are reliable, but failures of replicability have been a major issue in nearly all scientific areas of study, and machine learning is no exception. While failures of replicability in machine learning are multifactorial, one obstacle to replication efforts is the ambiguity in whether or not a replication effort was successful when many good models exist for a task. In this talk, we will discuss a new formalization of replicability for batch and reinforcement learning algorithms, and demonstrate how to solve fundamental tasks in learning under the constraints of replicability. We will also discuss how replicability relates to other algorithmic desiderata in responsible computing, such as differential privacy.
