Per ADR-0008: the v15 baseline reports MAPE but optimises MSE, which under-weights tail rows. Switching to objective='mape' applies gradient proportional to 1/|y| and lets the model focus where MAPE penalises. Targets co2_emissions, space_heating_kwh, hot_water_kwh, and peui_raw retain the default 'regression' objective (some rows have ~zero CO2 from heavy PV; MAPE objective destabilises near zero). Sample weights deferred to slice 16i if slice 16h's per-decile residuals still show tail bias after the objective switch. |
