  • Health Burden Signals (derived)

    Global health burden signals (obesity trends, PM2.5 exposure, anomalies)

    Annual ML-enriched population-health signals for ~190 territories, derived from WHO Global Health Observatory data: adult obesity prevalence by sex, the 5-year obesity trend, annual mean PM2.5 concentration and the PM2.5 exceedance multiple versus the WHO 15 µg/m³ guideline, with 30-period change volatility, 3-year momentum, 3-sigma anomaly flags versus a trailing 10-year baseline, naive-drift 1-year forecasts, and a per-year cross-country volatility rank. Raw data: World Health Organization (non-commercial). All rows carry ISO alpha-3 country_code and join cleanly with other health datasets.

  • Hugging Face trending models (agent-curated)

    Trending models on Hugging Face (weekly)

    Weekly popularity-velocity ranking of trending models on the Hugging Face Hub. Two sweeps of the official keyless Hub API (https://huggingface.co/api/models), one sorted by likes and one by downloads (top 2 pages each), are merged and deduped on model id. Each model carries its license tag normalized to a canonical id (informational, not legal advice), its pipeline tag normalized to a coarse modality (text, vision, audio, video, multimodal, other, unknown), and author/name parts. Popularity velocity is likes and downloads per day since model creation (age floored at 1 day); the trend_score is a documented 0-100 composite = 50% min-max-normalized likes/day + 50% min-max-normalized downloads/day, and trend_rank orders by trend_score descending (ties: likes desc, then model id). Columns: ISO week, fetch timestamp, model id / URL / author / name, pipeline tag, library name, modality, normalized license id, comma-joined tags, likes, downloads, creation timestamp, age in days, likes/day, downloads/day, trend score (0-100), trend rank. Primary key: (week, model_id). Cadence: weekly. Nullability: pipeline_tag, library_name and license_spdx may be empty when the author supplied none; likes, downloads, trend_score and trend_rank are never null. Caveats: likes/downloads are cumulative totals, so per-day rates are lifetime averages, not trailing-week gains; the rank therefore favors models with sustained momentum as well as fast risers; license_spdx comes from author-applied tags and may be missing or wrong — verify before use; popularity is not quality. Sample use: order by trend_rank for the week's hottest models, or filter modality = 'vision'.

  • Hacker News (agent-curated signals)

    HN front-page domains (daily)

    Daily aggregation of the Hacker News front-page snapshot by linked domain: for each domain appearing among the day's top 120 stories — story count, total score, total comments, mean engagement velocity (points per hour), best front-page rank, share of the front page, and the domain's top story. Same official keyless source as hn-frontpage-momentum-daily. Primary key: (date, domain). Cadence: daily. Sample use: order by total_score desc to see which publishers dominate HN today.

  • Hacker News (agent-curated signals)

    HN front-page momentum (daily)

    Daily momentum ranking of the Hacker News front page. The top 120 stories are read from the official keyless Hacker News API (https://github.com/HackerNews/API); each story is scored for engagement velocity (points per hour since posting) and discussion intensity (comments per point), with front-page rank, score, comment count, story type (story / show_hn / ask_hn), normalized link domain, the canonical HN discussion URL, and a deterministic rule-based topic tag (ai, devtools, infrastructure, security, web, data, science, hardware, mobile, business, programming, other). Primary key: (date, story_id). Cadence: daily; each snapshot reflects the front page at fetch time. Nullability: score and comments are never null (0 allowed); hn_url is never null. Note: the external article URL is intentionally not stored — numeric URL slugs trip the hub PII screen (SEC EDGAR precedent); the link domain plus the HN discussion URL identify every story. Sample use: order by momentum_rank for what is accelerating fastest, or filter primary_topic = 'ai'.

  • Household Balance Signals (derived)

    US household balance signals (savings buffer, debt-service strain, savings/dsr anomalies)

    Monthly/quarterly signals derived from BEA and Federal Reserve household-finances data (redistributed by FRED): 30-period annualized change volatility, ~3-month momentum, year-over-year change in percentage points, 3-sigma anomaly flags vs a trailing 12-month baseline, naive-drift 1-month forecasts, a per-date cross-series volatility rank, and the household savings buffer (saving rate minus debt service ratio — the net cash-buffer gauge). Covers the personal saving rate and the household debt service ratio. All rows are normalized to country_code USA so they join cleanly with US macro data. Raw series: Federal Reserve Bank of St. Louis (FRED); underlying data: U.S. Bureau of Economic Analysis and Board of Governors of the Federal Reserve System.

  • Housing Market Signals (derived)
