return_tensors

```python def retrieve(queries): # Tokenize the queries inputs = tokenizer(queries, padding=True, truncation=True, return_tensors="pt") # Perform retrieval using the LLM outputs = model(**inputs…

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…

- Ensure the new model integrates seamlessly with the rest of the retrieval pipeline. ### Example Implementation #### Step 1: Data Preparation Prepare your dataset for training and validation: ```python from transformers import AutoT…

def __init__(self, queries, passages, tokenizer): self.queries = queries self.passages = passages self.tokenizer = tokenizer def __getitem__(self, idx): query = self.queries[idx] passage = se…

inputs = tokenizer(term, return_tensors='pt', padding=True, truncation=True) outputs = model(**inputs) embeddings = outputs.last_hidden_state.mean(dim=1) # Mean pooling return embeddings ``` ### Step 4: Retrieve Synonyms B…

Here's an example of a hybrid approach that combines WordNet and context-aware embeddings: ```python from transformers import BertTokenizer, BertModel import torch import nltk from nltk.corpus import wordnet nltk.download('wordnet') toke…

reformulated_queries = [model.generate(tokenizer(f"reformulate: {q}", return_tensors="pt", max_length=512, truncation=True)['input_ids'], max_length=512)[0] for q in original_queries] reformulated_texts = [tokenizer.decode(output, skip_spec…

Once we have the profiling results, we can analyze them to pinpoint the slowest parts of the code. ### Step 3: Optimize the Code Based on the analysis, we can make targeted optimizations to improve performance. ### Example Code with Prof…
