DATA NOTES
データの出どころと、できないこと。
このサイトは公開データの比較メモです。行政手続きや不動産判断の代わりではありません。 取得元、変換、推定の限界をここにまとめます。
ML ベースライン
目的変数: vacancy_rate_or_symbol_proxy
| モデル | MAE | RMSE |
|---|---|---|
| global_mean | 0.20068 | 0.561085 |
| municipality_age_mean | 0.200121 | 0.564475 |
制約
・Single-snapshot municipality data is not enough for true time-series vacancy forecasting.
・Chiba symbols are converted to numeric proxies: ◎=5, ○=3, △=1, ×=missing.
・Kawasaki PDF extraction is layout-based and should be reviewed before production use.
