### 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 IVFPQ index nlist = 100 # Number of clusters m = 8 # Number of subquantizers index = faiss.IndexIVFPQ(faiss.IndexFlatL2(128), 128, nlist, m, 8) # 8 is…

[2026-03-19 22:57] xenonfun: ⏺ G=16 H=2: 54K tok/s, r=0.15, C=3.6 bits (highest capacity yet!), DC=0.03. 196 min ETA — about 3.3 hours for the epoch. Slower than G=8 (200K tok/s) but the 3.6 bit capacity vs 2.3 bits is significant. More g…

[2026-04-20 17:11] xenonfun: Important observations: 1. Neither feedback variant is catastrophically diverging at peak LR 3e-3. The model produces grammatically-shaped output; the damage is only at the vocabulary level, not structural.…

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…

Here's an optimized version of your code using `IndexIVFFlat` and enabling multi-threading: ```python import faiss import numpy as np # Assume we have a dataset of 100,000 vectors vectors = np.random.rand(100000, 128).astype('float32') #…

1. **Create an Index**: Choose an appropriate index type that balances speed and accuracy. 2. **Add Embeddings**: Add your embeddings to the index. 3. **Search for Nearest Neighbors**: Perform the search and optimize the parameters for bett…

To further optimize the query time, you can adjust the parameters: - **`nlist`**: Increasing `nlist` can improve accuracy but may increase memory usage and query time. - **`m`**: The number of subquantizers affects the trade-off between sp…

# Load the data df = pd.read_csv('data.csv') # Split the data into training and testing sets train_df, test_df = df.split(test_size=0.2, random_state=42) # Train the model model = SparseModel() model.fit(train_df) # Make predictions pred…

3. **Calculate Latency**: Compute the latency by subtracting the start time from the end time. 4. **Log Latency**: Use Python's logging module to log the latency for each query. ### Example Implementation Here's an example implementation …

- **Error Handling**: Use try-except blocks to catch and print errors, which helps in debugging. - **Verification**: Verify that the model and optimizer were loaded correctly after attempting to load them. This approach should help you deb…
