Weighted Sum

# Print the results print("\nWeighted Scores:") for option_name, score in sorted_options: print(f"{option_name}: {score}") if __name__ == "__main__": main() ``` ### How to Use the Script 1. Run the script. 2. Ente…

Option B: 41 Option C: 38 Option A: 34 ``` This output shows that Option B has the highest weighted score, followed by Option C and Option A. ### Conclusion This script provides a simple yet effective way to prioritize your tech criteria…

2. **Simulate Risk Occurrence**: Determine which risks occur based on their probabilities. 3. **Calculate Risk Score**: Compute the overall risk score by combining the probabilities and impacts of the occurring risks. ### Example Python Co…

Finally, you can combine the results from both sparse and dense retrievals. One common approach is to use a weighted sum of the scores from both methods. Here's a more complete example: ```python import numpy as np from sklearn.feature_ex…

- We use a pre-trained BERT model to generate embeddings for documents and the query. - `cosine_similarity` computes the similarity between the query embedding and document embeddings. 3. **Combining Scores**: - We combine the BM2…

with torch.no_grad(): doc_outputs = model(**doc_inputs) query_outputs = model(**query_inputs) doc_embeddings = doc_outputs.last_hidden_state.mean(dim=1) query_embedding = query_outputs.last_hidden_state.mean(dim…

def hybrid_ranking(sparse_scores, dense_scores, alpha=0.6): # Calculate weighted sum of sparse and dense scores hybrid_scores = alpha * sparse_scores + (1 - alpha) * dense_scores return hybrid_scores # Example usage: sparse_sco…

3. **Evaluation Metrics**: Use appropriate evaluation metrics to measure the relevance lift. Common metrics include Precision@k, Recall, and Mean Average Precision (MAP). 4. **Post-processing**: Consider post-processing steps such as re-ra…

if max_score == min_score: return np.zeros_like(scores) return (scores - min_score) / (max_score - min_score) def hybrid_ranking(sparse_scores, dense_scores, alpha=0.6): # Normalize scores to ensure they are on the same…

- Use `minimize` from `scipy.optimize` to find the optimal weights that minimize the MSE. ### Additional Considerations - **Normalization**: Normalize the queries if they are on different scales. - **Constraint**: Add constraints to th…

# Calculate the weighted sum of the queries weighted_sum = np.sum([weight * query for weight, query in zip(weights, queries)], axis=0) return weighted_sum def loss_function(weights, queries, true_values): # Calculate the we…

dense_scores = np.random.rand(num_queries, num_documents) # Test queries test_queries = np.random.rand(num_queries, num_documents) predictions = [] for i in range(num_queries): query = test_queries[i] sparse_scores_i = sparse_scor…

Use PyTorch to fuse the scores from sparse and dense searches: ```python def fuse_scores(sparse_scores, dense_scores, sparse_weight=0.5, dense_weight=0.5): # Convert scores to PyTorch tensors sparse_scores_tensor = torch.tensor(spa…

3. **Advanced Fusion Techniques**: Consider more advanced fusion techniques such as weighted sum, min-max scaling, or even more sophisticated methods like logistic regression or neural networks. ### Current Implementation Review Your curr…

- **Feedback Loops**: Incorporate feedback loops to continuously improve the system based on user interactions and performance metrics. ### Example Code Snippet Here's an example of how you might implement a hybrid query execution with dy…
