HELM chart to install NeuVector container cluster

Numpy-like library in swift. (Multi-dimensional Array, ndarray, matrix and vector library)

valkey-search is a C++ module which extends valkey with vector search and secondary indexing capabilities. It enables users to index and query data stored in Valkey using complex queries with filters while maintaining high performance and scalability.

Neural search transforms text into vectors and facilitates vector search both at ingestion time and at search time.

A Redmine plugin that adds AI agents, MCP Server, smart completion, and vector search.

Local-first persistent memory for OpenAI Codex: governed recall, progressive disclosure, no hosted vector database.

A queryable second brain over your scattered notes and docs - hybrid retrieval (vector + BM25), section-level citations, and an MCP server so AI agents can use it. ~300 lines, no LangChain.

ReShade add-on that makes DLSS 5 Neural Rendering cheaper: peripheral compression before the model and model passes every N frames with motion-vector reprojection

Cross-platform report engine for .NET. Describe a paginated document once in .rxaml markup or a fluent C# builder, supply your data, and get a vector PDF, bitmap pages, or an in-app view — rendered by plain .NET on SkiaSharp across Windows, macOS, Linux, Android, iOS and the browser (MAUI, Avalonia, WPF, Blazor).

(Committed) Vector oblivious linear evaluation

VSM/SVM based gem for simularity / classification / spam detection etc

Foreign-Numeric-Vector, a common lisp package supporting the use of foreign-stored arrays in common lisp for numerical work.

Support Vector Machine library built from RNum

Graphic Abstraction for vectorial rendering in a browser (support SVG, VML and canvas)

Linear algebra with statically checked physical dimensions.

Vectors are fun. Written for no particular reason other than trying out Ruby. Is likely pretty redundant, overall. Written on Ruby 1.9.1-preview 1 but should be mostly Ruby 1.8.x compatible. Again, vectors are fun.
