Camera-ready rebuttal figures — Feedback World Model Enables Precise Guidance of Diffusion Policy (NeurIPS 2026)

camera_ready_rebuttal_figures.zip contains 12 candidate figures (14 files, each as vector PDF, SVG and 300 dpi PNG), a print-size preview (atlas/figure_atlas.pdf), ready-to-use LaTeX captions (captions.tex), a Chinese guide to every figure (FIGURE_GUIDE_zh.md), a data audit, verification reports, the reported values used (source_data/) and the plotting code (python3 make_all_figures.py regenerates everything).

All numbers are aggregates reported in the manuscript and the author responses; nothing was imputed or simulated.

Status: these are candidate figures for the camera-ready version, not final published results. In particular, the real-robot 95% Wilson intervals (real_world_success_ci_provisional*) assume success counts of N x reported rate (N = 20) and are provisional until checked against the evaluation logs. Open items are listed in data_audit.md and FIGURE_GUIDE_zh.md.

Update 2026-10-17: recovered missing statistics

camera_ready_missing_statistics.zip fills two evidence gaps of the camera-ready draft, recomputed from the per-episode records of the original evaluations (no new experiments):

  • Residual time series (four LIBERO-Plus scenes x standard / camera-viewpoint OOD): median and IQR across episodes, per feedback update and on a normalized-progress axis.
  • Nine-task x three-method latent prediction MSE: episode-level mean +/- SEM, plus a version with the original figure's step-pooled estimator.

The package includes figures (PDF/SVG/PNG), captions, generated LaTeX tables, step-level data, a source manifest with file hashes, an audit of the original protocols, and a verification report. GUIDE_AND_CONCERNS_zh.md (Chinese) explains every figure and lists the open issues. Notably, the rebuttal's residual table pooled Light-Conditions episodes into its "Standard OOD" cohort, and the published figure mixed two MSE estimators. These are working materials, not final published results.


论文 camera-ready 的 rebuttal 候选配图包:12 张图(14 个文件,每个都有 PDF / SVG / 300 dpi PNG)、按印刷尺寸排版的图集、 LaTeX 图注、中文逐图说明(FIGURE_GUIDE_zh.md)、数据审计与校验报告、所用数值和绘图源码。真机 Wilson 区间所用的成功次数 是按 N × 成功率倒推的,尚待日志核实。

camera_ready_missing_statistics.zip(2026-10-17):残差时间曲线与九任务 MSE mean ± SEM 的补齐结果、图注、数据与核验报告;GUIDE_AND_CONCERNS_zh.md 给出逐图说明与需要作者确认的问题。
