SN21 training data v4 (live basket shape)
About SN21 AdTAO
SN21 training data v4: the live daily basket shape. 27,768 episodes, windows 2026-06-15 to 2026-08-14, every one with settled 7/14/28-day labels. Why. Same period as v2 (to 2026-08-04) and v3 (2026-08-05..14), re-issued in the live basket shape: campaign type, bid strategy, industry, change velocity, diagnostics, daily clicks, impressions and impression share are now in the training input, as they are in every live basket. Episode ids are basket ids (candidate key), not the v2/v3 ids. Record format. {episode_id, input, labels}: input is a daily basket episode exactly as the executor serves it ({episode_id, transition_key, payload, system_estimate}); labels per horizon carry cost_delta_pct, conversions_delta_pct, efficiency_delta_pct, goal_basis and finalized_on, as the scorer reads them. As of. Every payload is built as of the end of its own change window: no field uses data from after the change. Labels. Cost, conversions and efficiency deltas vs a 60-day pre-change baseline over the 7, 14 and 28 days after the change window, each with a 7-day settling period. efficiency_delta_pct is the CPA delta on a cpa goal basis and the conversion-value delta on a conversion_value basis. Every record has all three horizons. Held out. A held-out evaluation set is retained and never published. Every admission-corpus episode and any record within 72 hours on the same campaign was removed, and no window is later than the active corpus cutoff.
