jax-random-projections 1.0.1

sklearn's random projection with JAX to run on a GPU

JAX Random Projection Transformers

Using JAX to speed up sklearn's random projection transformers

Installation

Note: Installation with pip will install the CPU-only version of JAX

To use a GPU follow JAX's installation guide before installing jax-random_projections.

pip install jax-random_projections

Usage

from jax_random_projections.sparse import SparseRandomProjectionJAX

transfomer = SparseRandomProjectionJAX()
transfomer.fit_transform(X)

For the API documentation, refer to sklearn's SparseRandomProjection documentation. The only difference is that jax-random_projections currently only supports xla.DeviceArray and doesn't support dense_output=False and y for fit() This library currently only includes the SparseRandomProjection but a future release will also include GaussianRandomProjection.

jax-random_projections also includes SparseRandomProjectionJAXCached which uses a lru cache (maxsize=5) to speed up repeated calls by caching the random matrix for data with the same input dimension.
