Summary: This is a high-quality, accurate translation of a technically dense lecture on importance sampling. The mathematical content, statistical reasoning, and code comments are rendered faithfully and fluently, with correct MyST/Markdown syntax throughout. Minor issues include a slight inconsistency in translating 'importance sampling' (重要性采样 vs 重要性抽样) and an unexplained addition of font-setup code not in the source, neither of which affects comprehension or correctness significantly. Mathematical notation and LaTeX expressions are preserved accurately throughout all changed sections Technical explanations of importance sampling, variance divergence, and Monte Carlo failure are translated with precision and clarity, preserving nuanced statistical arguments Proper full-width Chinese punctuation and correct spacing around inline MyST directives (e.g., {doc}, {numref}) are consistently applied

Suggestions:

• [minor · formatting] lectures/imp_sample.md — Overview section, Python imports code cell: The translation's code cell adds extra lines (FONTPATH, mpl.font_manager, plt.rcParams) not present in the English source's import block. While this appears to be a standard font-setup addition used across translated lectures, it is a deviation from the source content within a code cell, which should ideally mirror the original exactly except for comments. → Confirm this font-loading addition is part of the standard translation build pipeline convention; if not required, remove it to match the source exactly.
• [minor · terminology] lectures/imp_sample.md — ## 重要性采样 (heading) vs ## 选择抽样分布 / 重要性抽样 elsewhere: The translation inconsistently renders 'importance sampling' as both '重要性采样' (heading) and '重要性抽样' (used throughout body text and other headings). While both are acceptable renderings, mixing them within the same document reduces terminological consistency. → Standardize on one term throughout, e.g., '重要性抽样', including the '## 重要性采样' heading, to match the more frequently used term elsewhere in the document.
• [nit · fluency] lectures/imp_sample.md — Distribution of sample mean, plot_estimates call captions: In the h2/h3 estimate plots, the imp_label argument is translated to '$h_2$ 生成' and '$h_3$ 生成' while the earlier corresponding call for h1 keeps '$h$ generating' untranslated (appears as English string literal passed to legend, not prose, so likely fine) — flagging only for consistency awareness since h2/h3 labels were translated but h1's was not. → For consistency, consider translating all imp_label string arguments uniformly (e.g., '$h$ 生成') if these are meant to appear in rendered plot legends.

Scope Correct	✅
Position Correct	✅
Structure Preserved	✅
Heading-map Correct	✅
Overall	10/10

Summary: The translation sync correctly applies all structural, code, and content changes from the source in matching positions with preserved heading structure and valid heading-map, aside from minor untranslated string inconsistencies.

Issues:

• Two figure captions were left untranslated in English ('Monte Carlo and importance sampling estimates' for fig-imp-estimates), while other analogous captions (fig-imp-estimates-h2, fig-imp-estimates-h3) were translated to Chinese - minor inconsistency
• Legend labels '$g$ generating' remain untranslated in plot_estimates calls while imp_label arguments were translated (e.g., '$h_2$ 生成', '$h_3$ 生成') - inconsistent translation of similar UI strings

Pull request overview

This translation-sync PR updates the Chinese lecture imp_sample to match the upstream source changes, including converting the computational examples from NumPy/Numba to JAX and aligning figure/styling metadata used by the book build.

Changes:

• Switched simulation / importance-sampling code cells from Numba-based implementations to JAX (jax.random, jax.jit, jax.vmap, jax.lax).
• Added GPU admonition include and a dependency install cell for jax, plus refreshed figure metadata blocks (captions/names).
• Updated translation sync state metadata (source-sha, sync date, tool version, mode).

Reviewed changes
