-Ensemble Framework: XGBoost + LSTM Fusion
-=========================================
-This script demonstrates the framework for combining the static state analysis of XGBoost
-with the temporal trend analysis of LSTM to produce a robust final prediction.
-
-Methodology:
-1. Load both trained models (XGBoost .json, LSTM .pth).
-2. Prepare input data:
-   - XGBoost: Takes single frame features (24 dims).
-   - LSTM: Takes sequence of last 10 frames (10x24 dims).
-3. Generate independent probabilities: P_xgb, P_lstm.
-4. Fuse predictions using Weighted Averaging:
-   P_final = alpha * P_xgb + (1 - alpha) * P_lstm
-5. Evaluate performance on the test set.

-Stacking Ensemble Framework (Advanced Fusion)
-=============================================
-Beyond simple weighted averaging, this script implements 'Stacking' (Stacked Generalization).
-It trains a Meta-Learner (Logistic Regression) to intelligently combine the predictions 
-of the base models (XGBoost + LSTM) based on the current context (e.g., game time).
-
-Architecture:
-1. Base Layer: XGBoost, LSTM
-2. Meta Layer: Logistic Regression
-   Input: [Prob_XGB, Prob_LSTM, Game_Time, Team_Alive_Diff]
-   Output: Final Probability
-
-Why this is better:
-- It learns WHEN to trust which model (e.g., trust LSTM more in late-game).
-- It can correct systematic biases of base models.
