怎么判断 Evidence 真的有帮助？

核心问题是：在同一写作位置、使用同一模型和任务时，提供检索文献片段会怎样改变首次输出？我们成对比较两种条件，保留持平、不可用和评审未完成的结果。

同一段原稿 · 比较是否提供 Evidence

01 · 固定写作位置

论文原稿

同一处写作点位 ▌

02 · 构造两组输入

两组共用

盲评 Agent

匿名标记两份首次输出为 X、Y

按续写质量判断：准确性、任务贴合度和可用性
输出：X 更优 / 持平 / Y 更优 / 两组均不可用

换序复评：X / Y → Y / X

盲评具体怎么判？

① 匿名两份输出
评审看到同一原稿和两份首次输出，但不知道哪份用了 Evidence。

② 比较并换序复评
根据当前任务的标准，按 X/Y、再按 Y/X 的顺序各评一次。

③ 复核分歧
两次结论不一致时再做第三次判定；未完成的评审也留在分母。

自动补全点位怎样分层？

在查看生成结果前，先核查检索片段是否含有能直接支撑下一步续写的具体命题；有则放在左侧机会组，否则放在右侧普通组。每个学科从可准入论文中均衡选取两组点位。50/50 是实验设计，不代表真实写作中两类点位各占一半。

AUTOCOMPLETE · 110

定量生物学、统计学、天体物理学

左侧 55 个、右侧 55 个点位；统计学采用 10 篇论文的复测结果。

AUTOCOMPLETE · 52

心理学与气候科学

左侧 26 个、右侧 26 个点位；心理学计入 9 篇，气候科学计入 4 篇。

表格里的百分比怎么算？

五学科共有 81 个左侧点位，其中 51 个点位的 Evidence 版本获评更优。持平、两组均不可用和评审未完成的点位仍计入分母。

51Evidence 版本更优

81该层全部点位

63%该层 Evidence 获评更优的比例

来源贡献是另一项复核：已进入复核的 22 个 Evidence 获胜点位中，16 个确认直接使用了检索论文；另有 29 个胜出点位尚待复核。

当前是开发阶段的模型评审结果，尚未完成独立人工复核；这些数字不代表正式 Benchmark 结论，也不能单独证明因果关系。

Predictive Coding: a Theoretical and Experimental Review

5 Discussion and Future Directions

…e ( A.K. Seth et al. (2012) ; A.K. Seth & Critchley (2013) ; A.K. Seth (2013) ) . The key advantage of predictive coding is that it offers a well-tested and mathematically principled framework in which to model these phenomena. These advantages may allow the modelling of considerably more complex interoceptive feedback loops than can be straightforwardly interpreted in terms of feedback control ( Barrett & Simmons (2015) ; Pezzulo et al. (2018) ; Tschantz et al. (2021) ) , and especially allows for the relatively straightforward construction of nested and hierarchical feedback control models.

…tive of a similar scheme widely used in robotics, whereby complex planning or reinforcement learning algorithms determine the desired forces to send to the actuators, however the actuators themselves are equipped with onboard PID controllers, to ensure that the expected force is actually produced by the motors, and to correct for minor deviations ( Johnson & Moradi (2005) ) occuring at the lower levels of translating motor commands into action. Predictive coding, then, would be a model of these inbuilt controllers at the periphery rather than the core action selection mechanisms in the brain.

展开完整文献摘录

However, as the authors point out, a limitation of the architecture is that it only uses the bottom-up flow of information, without integrating top-down predictions to modulate the activation of lower levels. Tani, (2019) provides a thorough review of related neurorobotics experiments, many of which carried out in the authors’ laboratory. A very interesting implementation is described in Hwang et al., (2018) , which the authors refer to as a predictive coding model. The adopted network is a multi-layer hierarchical architecture encoding visual and proprioceptive information. Although the work is far from the formulations laid in the free-energy principle ( Friston,, 2009 ) , the VMDNN (Predictive Visuo-Motor Deep Dynamic Neural Network) performs very similar operations.

查看模型评审原始理由（英文）

Both outputs are identical and deliberately empty with 'needs_evidence' action. The task requires continuing a paragraph about predictive coding as a model of peripheral controllers (like PID controllers in robotics) versus core action selection mechanisms. The single supplied source discusses predictive processing in cognitive robotics but focuses on visuo-motor deep dynamic neural networks, bottom-up vs top-down information flow, and neurorobotics experiments. It does not directly support claims about: (1) predictive coding as a model of peripheral/inbuilt controllers specifically, (2) the distinction between peripheral controllers and core action selection mechanisms in the brain, or (3) the PID controller analogy for interoceptive feedback. The source mentions hierarchical architectures and predictive coding in robotics, but the specific analogy being developed in the draft (predictive coding as peripheral controller vs. central action selection) is not directly supported by this source. A deliberate empty response with 'needs_evidence' is appropriate when no supplied source directly supports the content needed. Both outputs correctly identify this gap.
