Fast(!) manifold learning methods implemented in Rust with R bindings… For the modern-day single-cell Wannebe Pollock.

Overview

manifoldsR provides high-performance implementations of popular dimensionality reduction techniques:

  • UMAP (Uniform Manifold Approximation and Projection with various optimisers which makes this fast.)
  • t-SNE (t-Distributed Stochastic Neighbor Embedding - Barnes-Hut and FFT-accelerated Interpolation-based versions)
  • PHATE (Potential of Heat-diffusion for Affinity-based Trajectory Embedding)

The core algorithms are implemented purely in Rust without any kernel switching for speed while providing user-friendly R interfaces. The optimisations here make them in parts substantially faster than other libraries typically used in the R ecosystem to run these methods. The backbone here are the Rust crates that enable approximate nearest neighbour searches and the underlying manifold learning methods. The underlying philosophy is to strip out most additional features and focus on the core mechanics and make them as fast as possible, avoid abstraction layers and indirection wherever possible and let llvm do its magic to generate fast code.

Installation

Prerequisites

This package requires Rust to be installed on your system. If you don’t have Rust installed:

macOS and Linux:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Windows:

Download and run the installer from rustup.rs

After installation, restart your terminal and verify Rust is installed:

rustc --version

Install manifoldsR 

# Install from source

Please check out the website and associated vignettes. Changelog can be found here.

Roadmap

For now the package covers the most common embedding versions. Future features are likely to include:

  • Density-preserving versions of UMAP and tSNE, see Narayan, et al.
  • PacMap from Wang et. al., that should preserve global structure better.
