scores2

### Key Components and Techniques 1. **Weighted Ensemble**: Assign different weights to the scores from each component based on their reliability and performance. 2. **Thresholding**: Apply thresholds to filter out low-confidence scores. 3…

Let's assume you have two retrieval engines, `engine1` and `engine2`, and you want to dynamically adjust their weights based on their performance metrics. #### Step 1: Collect Performance Metrics You can collect performance metrics by com…

# Calculate accuracy for each engine accuracy1 = np.mean(np.argmax(scores1, axis=1) == true_labels) accuracy2 = np.mean(np.argmax(scores2, axis=1) == true_labels) # Update weights based on accuracy new_weights = (ac…

def update_weights(engine1_accuracy, engine2_accuracy): total_accuracy = engine1_accuracy + engine2_accuracy if total_accuracy == 0: return (0.5, 0.5) # Default equal weights if both accuracies are zero new_weights = (e…

new_weights = update_weights(engine1_accuracy, engine2_accuracy) print("Updated Weights:", new_weights) # Recompute ensemble scores with updated weights ensemble_scores = compute_weighted_ensemble_scores(scores1, scores2, weights=new_weigh…

# Compute ensemble scores ensemble_scores = compute_weighted_ensemble_scores(scores1, scores2, weights=weights) print("Current Ensemble Scores:", ensemble_scores) # Calculate predictions predictions1 = np.argmax(scores1…

#### 2. Normalization Normalize the scores to ensure they are on the same scale. #### 3. Advanced Fusion Techniques Consider using a weighted sum with normalization. ### Example Code ```python import numpy as np from sklearn.model_select…

# Example data scores1 = np.array([0.8, 0.2, 0.4]) scores2 = np.array([0.3, 0.7, 0.1]) labels = np.array([1, 0, 1]) # Example labels # Tune weights best_weights = tune_weights(scores1, scores2, labels) print(f"Best weights: {best_weights}…
