# Gap in Existing Research How Our RTGB Fills It
1 Most hybrids use fixed blend weights (e.g. simple average, soft voting) — same α for every sample RTGB uses a per-sample learned gate α — the GateNet decides blend ratio dynamically based on input context
2 LSTM and LGB are trained independently on the same target — no information flows between them RTGB's LSTM is trained on LGB's residuals, not raw targets — forced specialisation, explicit knowledge transfer
3 Stacking meta-learners (Ridge, XGB) take predictions as input only — ignore temporal context GateNet takes predictions plus tabular context features — the gate is context-aware, not just prediction-aware
4 Most LGB+LSTM papers (wind, solar) do parallel training then late fusion RTGB is sequential: LGB runs first, LSTM sees what LGB failed at — asymmetric roles by design
5 Residual boosting exists (GrowNet, GB-DNN) but uses homogeneous weak learners (all NNs or all trees) RTGB mixes heterogeneous paradigms — gradient boosting for global structure, LSTM for temporal error patterns
6 Gate/attention mechanisms in hybrids are applied to features or sequence steps, not to model predictions RTGB's gate operates at the prediction level — it is a learned meta-controller over two specialist outputs
7 Ablation studies rarely isolate the contribution of the blending layer RTGB has built-in ablation: LGB-only, LGB+LSTM-corrected, and full RTGB are all logged — contribution of each stage is measurable
8 No wind forecasting paper combines residual transfer + adaptive gating in a single end-to-end pipeline RTGB is the first tabular wind forecasting architecture to chain residual transfer → LSTM correction → learned per-sample gate
