KLineage: Recovering the Missing When of Kernel Optimization by Deoptimizing Experts
This work introduces KLineage, which learns this missing"when"knowledge from expert kernels: instead of relying on forward rollouts, KLineage walks expert implementations backward through validation-gated simplifications and reverses each accepted step into a reusable optimization skill.
