fru - Fast Random Forest Implementation [P]

Hello, I wanted to share the work my colleague and I have been doing, which has just been published in Software X journal . We developed a Rust-based implementation of Random Forest. It has bindings for both Python and R . Fru is highly optimized, offering competitive runtime performance and better scalability than popular implementations on these platforms. For Python, Fru outperforms the scikit-learn implementation by several factors, and in some scenarios it can be hundreds of times faster. In R, Fru is typically a few dozen percent faster than the ranger package, though the speedup can reach several times faster depending on the use case. The model also includes a novel implementation of permutation importance, which provides an additional performance boost. Thanks to its layered design, we were able to easily create bindings for both Python and R. In Python, we use Arrow PyCapsule, which allows the model to work seamlessly with any compatible library, including pandas, polars, pyarrow, and many others. paper R package Python package submitted by /u/kpiwonski [link] [留言]
