WebLSHForest could use parallelism to be faster, but so can (and will) the exact neighbors methods. In theory in LSHForest, each "tree" could be stored on entirely different machines, providing memory benefits, but scikit-learn can't really take advantage of this. Having said that, I would also try with higher n_features and n_queries. We Web29 mrt. 2024 · The speed-precision tradeoff is governed by the leaf_size and no_trees parameters. Increasing leaf_size leads the model to produce shallower trees with larger leaf nodes; increasing no_trees fits more trees.. In-memory queries.

WebLSHForest has two main hyper-parameters: n_estimators and n_candidates. The accuracy of queries can be controlled using these parameters as demonstrated in the following plots: As a rule of thumb, a user can set n_estimators to a large enough value (e.g. between 10 and 50) and then adjust n_candidates to trade off accuracy for query time.
