Reinforcement Learning from AI Feedback (RLAIF)
Definition
RLAIF uses AI evaluations as a basis for reinforcement learning.
A training approach in which an AI system generates evaluations, critiques, or preference labels from which a reward model or other feedback signal is derived for subsequent optimization with reinforcement learning.
Simply explained
An AI evaluator assesses responses; feedback is generated from this, with which a model continues learning.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
An AI critic evaluates response pairs based on human-defined principles; from this, a reward signal is generated for further optimization of a model strategy.
Limits and pitfalls
- Considering AI feedback as independent or error-free, equating RLAIF with any use of synthetic preferences or fully autonomous alignment, or removing human guidelines, audits, and oversight.
Origin & history
RLAIF became known in works on Constitutional AI and scalable alignment from 2022 onwards.
Use in mid-sized companies
- Possible application: An AI critic evaluates response pairs based on human-defined principles; from this, a reward signal is generated for further optimization of a model strategy.
