Basic reward modeling has two steps:
Recursive reward modeling takes the basic setup, but has another agent trained to help the user give feedback.
Reward modeling aims to solve the “agent alignment problem”, which is to produce behavior that is in accordance with the user’s intentions. The agenda only aims to align one AI agent to one user, leaving out the problem of e.g. aggregating different preferences.
The level of capability of the agent being aligned is not clear from the paper (e.g. is reward modeling intended to be able to align superintelligent AI?).
No specific assumptions.
No specific assumptions.
The reward modeling paper lists two assumptions:

The paper also discusses alternative agendas and their relation to reward modeling.|
|New safety research agenda: scalable agent alignment via reward modeling||2018-11-20||Victoria Krakovna||LessWrong||Google DeepMind||Jan Leike||Recursive reward modeling, iterated amplification||Blog post on LessWrong announcing the recursive reward modeling agenda. Some comments in the discussion thread clarify various aspects of the agenda, including its relation to Paul Christiano’s iterated amplification agenda, whether the DeepMind safety team is thinking about the problem of whether the human user is a safe agent, and more details about alternating quantifiers in the analogy to complexity theory. Jan Leike is listed as an affected person for this document because he is the lead author and is mentioned in the blog post, and also because he responds to several questions raised in the comments.|
