Evidencepartial
our stage-wise SFT paradigm unlocks a higher performance ceiling for a lightweight reinforcement learning (RL) stage
Implicationpartial
Directly stated in the abstract and analysis section as a core contribution.
Verificationpartial

Evidencepartial
GraphWalker enhances generalization to out-of-distribution reasoning paths.
Implicationpartial
Explicitly stated in the abstract and analysis section with specific benchmark names.
Verificationpartial
partial
Evidencepartial
First, the agent is trained on structurally diverse trajectories synthesized from constrained random-walk paths, establishing a broad exploration prior over the KG
Implicationpartial
Directly and clearly described in the abstract and framework section.
Verificationpartial
partial
Evidencepartial
Second, the agent is further fine-tuned on a small set of expert trajectories to develop reflection and error recovery capabilities.
Implicationpartial
Directly and clearly described in the abstract and framework section.
Verificationpartial
partial
Evidencepartial
Prompting-based methods lack the dedicated parameter updates needed to robustly navigate noisy KGs.
Implicationpartial
Directly stated as a limitation of prior work in the analysis section.

Implicationpartial
Explicit numeric result provided in the main results table.
Verificationpartial
partial
Evidencepartial
RL optimization requires a competent SFT prior: without sufficient exploration capacity, the agent cannot discover rewarding trajectories, rendering policy optimization ineffective
