Uncertainty-Guided Progressive Contraction for Efficient Reasoning
October 8, 2026
This framework improves reasoning post-training efficiency by concentrating optimization on high-value reasoning trajectories using Monte Carlo reasoning trees. By profiling process-level uncertainty, the method compresses reasoning supervision without losing model capability.
HOW THIS AFFECTS YOU
