imate 0.25.2

Implicit Matrix Trace Estimator. Computes the trace of functions of implicit matrices. Accelerated on CPU and CUDA-capable GPU devices.

imate, short for Implicit Matrix Trace Estimator, is a modular and high-performance C++/CUDA library distributed as a Python package that provides scalable randomized algorithms for the computationally expensive matrix functions in machine learning.

Python wheels for imate for all supported platforms and versions in the above are available through PyPI and Anaconda Cloud. If you need imate on other platforms, architectures, and Python or PyPy versions, raise an issue on GitHub and we build its Python Wheel for you.

^{1. Our wheels for PyPy are exclusively available through pip and cannot be installed using conda.}

^{2. MacOS does not natively support NVIDIA GPUs.}

Performance

imate is scalable to very large matrices. Its core library for basic linear algebraic operations is faster than OpenBLAS, and its pseudo-random generator is a hundred-fold faster than the implementation in the standard C++ library.
