ECT Gap Calibration — Bilingual Beamer (学术交流版)

A 20-minute Tsinghua / domestic academic-exchange deck on finite-budget gap calibration for Easy Consistency Tuning (ECT). Chinese-primary with English secondary, compiled with XeLaTeX.

Build

latexmk -xelatex -interaction=nonstopmode -halt-on-error main.tex

or manually (the references use an inline thebibliography, so no bibtex pass is required):

xelatex main.tex
xelatex main.tex      # second pass to resolve \cite numbers

Files

• main.tex — the deck (20 slides incl. section dividers).
• bilingual-macros.tex — bilingual helpers, cards, \thulogo (conditional logo).
• beamer*themethubeamer.sty — Tsinghua purple beamer theme (local copy).
• refs.bib — BibTeX references for the companion paper (the deck itself uses an inline thebibliography, so refs.bib is for provenance / the paper).
• figures/ — publication PDFs copied from the recurrence_of_ect code repo (q256_paired_seed_plot, q256_effect_heterogeneity, toy_lr_control, toy_separation, true_sg_error_vs_g_budget, …).
• tables/ — ready-made LaTeX result tables (copied from the code repo for provenance; the deck renders the numbers inline in beamer-native tabular).

Optional: Tsinghua logo

The deck shows thulogo.pdf on the cover, section dividers, and closing slide only if the file is present (via the conditional \thulogo macro). Drop thulogo.pdf into the project root or figures/ to enable it; the deck compiles fine without it.

Dependencies

XeLaTeX (TeX Live or MiKTeX) with: beamer, ctex/xeCJK, fontspec, tcolorbox (skins, breakable), pgfplots, tikz, booktabs, natbib (loaded by the theme). A Simplified-Chinese font (Microsoft YaHei / PingFang SC / Noto Sans CJK SC / Source Han Sans SC / Fandol) is auto-detected.
