  UMAP C++ implementation

Since the Ruby language is a relatively minor language in the field of data analysis, it is often the case that a library that implements what you want to do does not exist. In such cases, you can look for libraries in languages such as C or Rust to build Ruby bindings. GitHub's search allows you to search for code by language. This can be used to find libraries for C. Since GitHub allows tagging of projects, searching for the target tag can also be helpful. However, UMAP seems to be difficult to implement, and I could not find a C library that implements UMAP. Instead, we found a library that implements UMAP in C++. That is Umappp.

  An R package implementing the UMAP dimensionality reduction method.

Umappp is a C++ library implemented by Aaron Lun. it is developed based on the R library uwot. it is implemented in C++ and uses OpenMP, so high performance is expected.

  Ruby Interface for C++ Extensions

  

There are two ways to write Ruby extensions in C++. One is Rice and the other is extpp. In this case, I used Rice because I wanted to use numo.hpp to link Numo::NArray and C++.
