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...

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.

A Splay Tree is a self adjusting binary search tree with the additional property that recently accessed elements are quick to access again. This makes it useful for caches because the most commonly accessed elements will be the fastest ones to access. This tree has an additional feature that allo...

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.

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

GUI for sortable tree to manage data organized in tree with ancestry gem.

A binary tree of one-time singatures known as a merkle tree. Often used in distributed systems such as Git, Cassandra or Bitcoin for efficiently summarizing sets of data.

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

Print directory or structured data in a tree like format.

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 ...

A self balancing avl binary search tree class. Also includes BinarySearchTreeHash which is a hash like class that internally uses binary search tree.

git-status-tree is a command line tool that shows git repository changes in a file tree.

Tree_hierarchy allows to form a tree structure based on parent-child relationship with simple and fast computation for large records. Additional feature of updating the parent record with the sum of its child value

This library can be used to build a tree structure, and render or print it like an ASCII graph. It can be used to implement a directory tree viewer or something like that.

Hitsuji is a library that implements a tree data structure, where each node is represented by a value, points to other values, or performs a function on some values. When the tree is updated, the inputs to the functions will change, hence changing the outputs, eventually propagating the u...

Guard::Treetop automatically compiles your treetop grammars

Provides a generic tree data structure with ability to store keyed node elements in the tree. The implementation mixes in the Enumerable module.

This gem implements a rooted, ordered tree, with a focus on easy iteration over nodes and access to basic tree properties. Formerly known as "rooted_tree".

This library allows you to input a tree structure (node with children), a context, and comparators then outputs you the matching tree structure.
