| ============================================================ | |
| TEMPLATE: landscape_4col (ARIS fork) | |
| CANVAS: 60in × 36in landscape (ICML / NeurIPS / generic landscape) | |
| LAYOUT: header → optional banner → 4 body columns → optional takeaways → footer | |
| USE WHEN: standard ML conference poster with 3-5 content cards per column, | |
| mix of figures + equations + small tables. | |
| HOW TO USE: | |
| 1. Copy this file to your working directory as `poster.html`. | |
| 2. Edit the DESIGN TOKENS in `:root` to your lab/venue colors. | |
| 3. Replace TODO content placeholders (search for "TODO"). | |
| 4. Run `python tools/run_gates.py poster.html --tokens design_tokens.json` (the default driver: preflight -> style -> measure -> polish; design_tokens.json is the design-direction pack written at lock time -- SKILL.md Step 2.5) to align columns and check style/structure. | |
| 5. Run `python tools/render_preview.py poster.html` to produce the PDF. | |
| NOTE: as shipped, this scaffold passes `preflight` (structure) but is | |
| EXPECTED to FAIL `measure`/`polish` -- figures are commented out and copy | |
| is TODO stubs, so columns only fill the top of the canvas. Those two gates | |
| judge a FILLED poster; balance them once you've added real content. See | |
| templates/README.md ("Scaffolds, not finished posters"). | |
| MEASURE ROLES: every layout-critical element carries `data-measure-role`. | |
| Generic measurement scripts depend on these — do not remove. | |
| CANVAS RETARGETING: to print at another size, change the canvas in exactly | |
| TWO places that must stay in sync -- the `@page { size: ... }` rule and the | |
| `.poster { width/height }` (also the `@media print .poster { width/height }`). | |
| Example: ICLR 2026 main conference uses 185cm 90cm landscape (official print | |
| service spec) -- set @page to `185cm 90cm`, width to `1850 * var(--u)` and | |
| height to `900 * var(--u)` (and the print-override .poster to `185cm`/`90cm`). | |

| Impute a feature twice — once from $\nu_j = E[X^j\mid X^{-j}]$, once from $\rho_j = E[X^j \mid X^{-j}, y]$ — then compare losses in pairs. Under the null the two imputations have the same law, so <strong>no train–test split is needed</strong>. We rebuilt Algorithms 1–4 and an HRT baseline from the PDF: <strong>all six claims reproduce</strong>, and we add one caveat the paper does not state. | |
