A RL lecture argues KL regularization can improve generalization over SFT
burny_tech · x · 2026-07-29
- The post highlights a lecture on regularization in RL, centered on why the KL penalty matters and how it shapes training.
- It also points to papers and theory suggesting RL can generalize better than SFT in some settings.
- The broader point is that many ML control problems rhyme: issues seen when optimizing reward models may recur when controlling agent rubrics.
