Search Phase

Here's an example using the `IndexHNSW` index, which is more scalable and efficient for large datasets: ```python import numpy as np import faiss # Assuming I have a dataset of vectors vectors = np.random.rand(1000, 128).astype('float32')…

# Normalize the vectors for cosine similarity faiss.normalize_L2(vectors) # Create an IVFPQ index nlist = 100 # Number of clusters m = 8 # Number of subquantizers index = faiss.IndexIVFPQ(faiss.IndexFlatL2(128), 128, nlist, m, 8) # 8 is…

- `efConstruction` and `efSearch` parameters control the construction and search phases, respectively. 2. **IVFPQ Index**: - `IndexIVFPQ`: Creates an IVFPQ index with a specified number of clusters (`nlist`), subquantizers (`m`), and…

index = faiss.IndexIVFPQ(quantizer, 128, nlist, m, nbits) # Train the index index.train(vectors) # Add vectors to the index index.add(vectors) # Set the number of probes index.nprobe = nprobe # Search for the nearest neighbors D, I = in…

quantizer = faiss.IndexFlatL2(embedding_dim) index = faiss.IndexIVFFlat(quantizer, embedding_dim, nlist) # Train the index index.train(document_embeddings) # Add the document embeddings to the index index.add(document_embeddings) # Gener…

- Use multi-threading or multi-processing to handle multiple batches concurrently. 4. **Increase Available Memory**: - If possible, increase the available memory by adding more RAM or using a machine with more resources. - Conside…
