Medium GrooveSquid.com (original content) Medium Difficulty Summary
A new study explores how humans perceive random variables and finds that machine learning models can be influenced by these biases when aligned with human feedback. The researchers propose a novel approach called KTO that maximizes the utility of generations rather than just predicting preferences, achieving comparable or better performance on large datasets without requiring additional information.
Low GrooveSquid.com (original content) Low Difficulty Summary
This research shows how humans perceive random variables and how it affects machine learning models. It finds that some ways to align models with human feedback can be influenced by these biases. The study proposes a new approach called KTO that is different from the usual way of doing things, but it works just as well or even better on big datasets.
