rubydown is R Markdown clone for Rubyists.

Computer vision datasets, transforms, and models for Ruby

High performance t-SNE for Ruby

High performance factorization machines for Ruby

Anngler is an approximate nearest neighbor search for points in n-dimensional space that are close in terms of cosine distance to a given point. The gem is built with serverless architecture in mind with Redis but it also offers a local in-memory storage.

satellite orbit calculation, power calculation, etc.

CArray interface to Numo::NArray

OpenAI CLIP embeddings, uses ONNX models. Allows to create embeddings for images and text

The Ruby library, Documentrix, is designed to provide a way to build and query vector databases for applications in natural language processing (NLP) and large language models (LLMs). It allows users to store and retrieve dense vector embeddings for text strings.

High level plug-and-play interface for composing Machine Learning applications

Ruby implementation of the parsing and computation of ephemerides from NASA/JPL Development Ephemerides DE4xx and IMCCE INPOP

To expand ruby math operations this gem call to others such as Numo:narray and others and implements methods onto them to deal with our needs

Gaussian Filter

Reaction diffusion system (Gray-Scott model).

Hanny is a Hash-based Approximate Nearest Neighbor (ANN) search library in Ruby. Hash-based ANN converts vector data into binary codes and builds a hash table by using the binary codes as hash keys. To build the hash table, Hanny uses Locality Sensitive Hashing (LSH) of approximating cosine similarity. It is known that if the code length is sufficiently long (ex. greater than 128-bit), LSH can obtain high search performance. In the experiment, Hanny achieved about twenty times faster search speed than the brute-force search by Euclidean distance.

Anomaly detection using gaussian distribution, written in ruby

A Ruby FFI interface to the JACK Audio Connection Kit

Ruby code for encoding, decoding, and processing positional audio. This code accompanies my educational video series about sound.

Meshgrid generator for 2D & 3D Numo::Narray.

Function module similar to `filter` in MatLab or Octave.
