The Ethics of Reward Shaping

I read three great articles over the weekend by Renee DiResta, Chris Wiggins, and Janelle Shane that touched on a topic that’s been troubling me: In machine learning, we take our cost functions for granted,... Continue

Benchmarking Machine Learning with Performance Profiles

A common sticking point in contemporary reinforcement learning is how to evaluate performance on benchmarks. For a general purpose method, we’d like to demonstrate aptitude on a wide selection of test problems with minimal special... Continue
