Self-Rewarding
A training mechanism in which a model evaluates or scores its own outputs, used to construct training signals in the absence of external annotations. A typical risk of this approach is reward hacking.
Timeline (last 90 days)
The typical failure mode of self-rewarding methods is reward hacking: the model learns to produce answers that it easily scores high on itself rather than answers that are genuinely correct, causing scoring ability and generation ability to drift in tandem and the training signal to become distorted.
JOLT is not the first work to attempt to compress post-training costs; previous directions include rejection sampling fine-tuning, the direct preference optimization (DPO) family of methods, and various self-rewarding mechanisms.
