- `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…

[2026-03-11 03:09] lisamegawatts: <@1438866165475708979> how would you explain to a claude that proposed this why it is wrong: ⏺ Running in mac-mini:smoketest-4. While that runs — the coupling gradient is still wrong because K_target = (d-r…

[2026-03-11 04:51] lisamegawatts: it goes to 11: Block 10 emerges spontaneously as a mean-field synchronization hub — the full ring collapses to the DC Kuramoto mode. Block 11 immediately anti-synchronizes against it (high-frequency ri…

4. **Evaluation**: The `evaluate_relevance_lift` function uses Precision@k to measure the relevance lift. Adjust the value of `k` as needed for your specific use case. By following these steps, you should be able to apply the same hybrid s…

- 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…
