Convert a binary tree to array and vice versa.

Generates XSLT to produce a Polyrex document from a tree-like XML structure.

Drag&Drop GUI for awesom_nested_set. Render Tree Helper. Very fast! Ready for Rails 4

Drag&Drop GUI helper for awesome_nested_set gem. Sortable tree view helper

A gem that adds simple support for organizing ActiveRecord models into parent–children relationships.

Rumale is a machine learning library in Ruby. Rumale provides machine learning algorithms with interfaces similar to Scikit-Learn in Python. Rumale supports Support Vector Machine, Logistic Regression, Ridge, Lasso, Multi-layer Perceptron, Naive Bayes, Decision Tree, Gradient Tree Boosting, Rando...

A RBTree is a sorted associative collection that is implemented with a Red-Black Tree. It maps keys to values like a Hash, but maintains its elements in ascending key order. The interface is the almost identical to that of Hash. This is a fork of the original gem that fixes various bugs on Ruby ...

A tree structure for Mongoid documents using the materialized path pattern

This gem facilitates modeling a test suite that is written in Gherkin (e.g. Cucumber, SpecFlow, Lettuce, etc.). It does this by providing an abstraction layer on top of the Abstract Syntax Tree that the 'cucumber-gherkin' gem generates when parsing features, as well as providing models for featur...

AI4R is a lightweight, educational Ruby library featuring clean implementations of core machine learning and AI algorithms—such as decision trees, neural networks, k-means, genetic algorithms, and even a bit size Transformers architecture covering encoder, decoder, and seq2seq variations. Designe...

merkletree - build your own crypto hash trees; named after Ralph Merkle who patented hash trees in 1979; grow your own money on trees

A crit bit tree, also known as a Binary Patricia Trie is a trie (https://en.wikipedia.org/wiki/Trie), also called digital tree and sometimes radix tree or prefix tree (as they can be searched by prefixes), is an ordered tree data structure that is used to store a dynamic set or associative array...

Rumale::Ensemble provides ensemble learning algorithms, such as AdaBoost, Gradient Tree Boosting, and Random Forest, with Rumale interface.

SVMKit is a machine learninig library in Ruby. SVMKit provides machine learning algorithms with interfaces similar to Scikit-Learn in Python. SVMKit supports Linear / Kernel Support Vector Machine, Logistic Regression, Linear Regression, Ridge, Lasso, Factorization Machine, Naive Bayes, Decision ...

Installs 5 commands that process a git directory tree. Directories containing a file called .ignore are ignored. The git-commitAll command commits all changes to each repository in the tree. The git-evars command writes a script that defines environment variables pointing to git repos. The git...

The library can parse an SQL query (a string) to represent the query using a syntax tree, and it can generate an SQL query from a syntax tree. The syntax tree ca be used to inspect to query, or to modify it.

Print directory or structured data in a tree like format.

To make it easier to build and manipulate SQL queries, sql_tree can parse an SQL query to represent it as a tree of nodes and can generate an SQL query given a tree as input

acts_as_better_tree is great for anyone who needs a fast tree capable of handling millions of nodes without slowing down on writes like nestedset or on reads like a standard tree.
