Open Source Ruby Machine Learning Software

Clever Algorithms collects clear, cookbook-style descriptions of nature-inspired optimization and learning methods, organized so you can pick an algorithm and apply it quickly. Each entry follows a consistent template: motivation, strategy, pseudocode, parameter choices, variations, and references, making it easy to compare approaches. The catalog spans evolutionary algorithms, swarm intelligence, immune systems, simulated annealing, tabu search, and other metaheuristics, plus guidance on when and how to tune them. Example implementations and worked problems show how to encode solutions, define fitness, and balance exploration with exploitation. The emphasis is on pragmatism—enough theory to understand why an algorithm works, and enough detail to get it running in your environment. It’s a useful starting point for students and practitioners who want to prototype, benchmark, or hybridize algorithms without digging through scattered academic papers.

Lita is a chat bot written in Ruby that brings more fun and efficiency to your favorite chat service.

It's ideal for businesses that want a chat service that is not only efficient, but friendly and personalized as well. Lita can become your very own robot companion, tailor-made for your business. Lita can be customized according to your company's culture and needs. It can be used to automate various time-consuming and error-prone tasks, while also letting your company members have fun and create a sense of community.

This Ruby program takes in a topology specification for an artificial neural network and emits optimized C code (using SSE intrinsics) that implements fast forward and backward propagation for that specific topology.
