UnverifiedTheoretical analysis shows that, under certain regularity conditions, the target Q-function estimation and policy value convergence rates of DFQI are comparable to estimators that use only target data, while it can effectively exploit source data to reduce variance.73% similarUnverifiedIn each Bellman update, DFQI simultaneously updates the target Q-function and borrows source information, achieving tighter coupling.72% similarUnverifiedThe controlled framework combines stage-specific control, multiple representation and adaptation objectives, full-distribution metrics, and hierarchical inference over class allocation, support set reconstruction, and optimization runs.72% similarUnverifiedThe authors establish statistical guarantees for DFQI's target estimation and policy learning in a stationary discounted setting, covering both homogeneous and heterogeneous transition kernels.69% similarUnverifiedThis optimization focuses on the vLLM inference framework and the MXFP4/NVFP4 quantization paths, involving writing or adjusting dedicated compute kernels.68% similar
