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')…

### Using Quantization for Efficiency Quantization can further reduce the memory footprint and speed up the search process. FAISS supports various quantization techniques, such as PQ (Product Quantization). Here's an example using PQ: ``…

# Normalize the vectors for cosine similarity faiss.normalize_L2(vectors) # Create an HNSW index M = 16 # Number of links per node efConstruction = 200 # Number of neighbors to consider during construction efSearch = 64 # Number of neig…

Here's an improved version of your code incorporating these suggestions: ```python import numpy as np import faiss # Initialize the FAISS index outside the function def initialize_faiss_index(dim, use_gpu=False): if use_gpu: r…

This example demonstrates how to use FAISS for efficient similarity search on a large dataset of document embeddings. By leveraging FAISS, you can achieve significant improvements in both memory usage and search performance. [Turn 4860] Us…
