One-line takeaway
Belief-Trajectory Energy measures how an LLM revises its predictions layer by layer rather than only the final output, grounded in Fisher-Rao geometry, and serves as a model-relative difficulty signal on reasoning tasks.
BTE（信念轨迹能量）衡量大模型在各层逐步修正预测的过程，而不只看最终输出，理论上对应 Fisher-Rao 几何下的预测修正，可作为推理任务难度信号。
