Pull Request resolved: https://github.com/facebookresearch/faiss/pull/3154
Using the benchmark to find Pareto optimal indices, in this case on BigANN as an example.
Separately optimize the coarse quantizer and the vector codec and use Pareto optimal configurations to construct IVF indices, which are then retested at various scales. See `optimize()` in `optimize.py` as the main function driving the process.
The results can be interpreted with `bench_fw_notebook.ipynb`, which allows:
* filtering by maximum code size
* maximum time
* minimum accuracy
* space or time Pareto optimal options
* and visualize the results and output them as a table.
This version is intentionally limited to IVF(Flat|HNSW),PQ|SQ indices...
