RLHF-Blender: A Configurable Interactive Interface for Learning from Diverse Human Feedback

no code implementations8 Aug 2023 Yannick Metz, David Lindner, Raphaël Baur, Daniel Keim, Mennatallah El-Assady

To use reinforcement learning from human feedback (RLHF) in practical applications, it is crucial to learn reward models from diverse sources of human feedback and to consider human factors involved in providing feedback of different types.

Is that really a question? Going beyond factoid questions in NLP

1 code implementation IWCS (ACL) 2021 Aikaterini-Lida Kalouli, Rebecca Kehlbeck, Rita Sevastjanova, Oliver Deussen, Daniel Keim, Miriam Butt

Research in NLP has mainly focused on factoid questions, with the goal of finding quick and reliable ways of matching a query to an answer.
