Machine Learning Visualized is a book of Jupyter Notebooks that implement and mathematically derive machine learning algorithms from first principles. Each notebook's output is a visualization of the algorithm during training, converging at its optimal weights. Chapters cover optimization, clustering and reduction, linear models and activation functions, and neural networks.
Neanderthal is a Clojure library for fast native matrix and linear algebra, built with native BLAS and LAPACK for number crunching and wrapped in a small Clojure layer. It offers pluggable engine implementations, including a pure Java engine, plus primitive versions of map and reduce.
Nightmare is an introductory course on binary exploitation and reverse engineering built around CTF challenges. Its materials are structured linearly and include documented write-ups for each challenge, with most modules offering multiple problems per topic so learners can apply an attack technique to different iterations. The course uses only free and open source tools, and its static site is built with mdbook.
An NLP toolbox for Matlab under development by researchers at UC Berkeley's AMPLab, intended to process natural language within Matlab rather than switching to other languages. It includes modules for text tokenization, text preprocessing such as stop word removal and stemming, and learning algorithms including linear regression, decision trees, support vector machines and a Naive Bayes classifier.
NumPy is a Python library providing a multidimensional array object and routines for fast operations on arrays, including mathematical, logical, sorting, Fourier transforms, linear algebra and random simulation. It is open source under a BSD license and is described as the fundamental package for scientific computing in Python, with core code written in optimized C.
OMNIWeb is a NASA Space Physics Data Facility service providing hourly near-Earth solar wind magnetic field and plasma data, energetic proton fluxes above 1 to 60 MeV, and geomagnetic and solar activity indices. It offers plots, listings, output files, scatter plots with linear regression fits, and event or hourly lists with filtering.
The OpenConnect VPN server (ocserv) is an open source Linux SSL VPN server designed for organizations requiring a remote access VPN with enterprise user management and control. It secures VPN channels using standard protocols like TLS and Datagram TLS, and its performance scales linearly with the number of CPUs.
Orange is an open-source machine learning and data visualization toolbox. It offers visual programming in which widgets are placed on a canvas and connected to load datasets and analyze data. It supports interactive visualization methods including box plots, scatter plots, decision trees, hierarchical clustering, heatmaps, MDS, t-SNE and linear projections. Extensions add text mining, network analysis and other specialized capabilities.
Park School Mathematics is a site presenting a series of mathematics books, from Book 1: Reasoning and Proving through Book 10: Functions and Models II, plus additional custom books. Book pages list lessons covering topics such as combinatorics, linear equations, quadratic models, graph theory, geometric proof, circular functions, algorithms, logarithms and recursion.
ParsaTV combines linear channel streaming with on-demand or catch-up television pages.
Prophet is a forecasting procedure implemented in R and Python. It provides automated forecasts that can be tuned by hand, and is based on an additive model with non-linear trends and yearly, weekly and daily seasonality plus holiday effects. Facebook released it as open source, available on CRAN and PyPI.
RadioVatani combines linear channel streaming with recent on-demand television programmes.
Replay QA is an autonomous testing harness for web applications. Agents explore an app, write and run tests in a Chromium browser, and record deterministic runtime sessions. It reports bugs such as runtime bugs, UI glitches, accessibility issues, performance problems and security vulnerabilities, with a root cause and suggested fix. Reports go to GitHub, Linear, Jira or other HTTP endpoints.
Sauna is a proactive AI teammate described by its site as an AI agent with a computer of its own. It researches, follows up and builds apps for users and teams, and connects to tools such as Linear, GitHub, Notion, Gmail and Slack. It runs in the cloud and is available on the web, iOS, iMessage, Slack and email.
ScalaNLP is an umbrella project for machine learning and numerical computing libraries, including Breeze and Epic. Breeze covers linear algebra, numerical computing and optimization. Epic is a statistical parser and structured prediction library. The site also lists Puck, a GPU-powered parser built on grammars produced by the Berkeley Parser.
SciRuby is a project providing tools for scientific computing and data visualization in Ruby. Its releases include NMatrix, a linear algebra library with dense and sparse matrix storage and tensor support, alongside visualization and statistics gems. The project describes itself as currently alpha, and it notes its gems are tested but not battle-hardened. SciRuby and NMatrix are available under the BSD three-clause license.
Stan is software for Bayesian data analysis that combines statistical modeling capabilities with user-friendly interfaces and open-source development. Its probabilistic programming language supports applications from simple linear regression to multi-level models and time-series analysis. Interfaces exist for Python, Julia, R, and the Unix shell, usable on laptops, clusters, or in the cloud. Official documentation covers the language, inference algorithms, and built-in functions.
Stat Trek provides free online tutorials and calculators covering statistics and probability. Tutorial topics include AP Statistics, probability, linear regression, ANOVA, survey sampling, and matrix algebra, explained in plain English. The site also offers practice exams and a random number generator and sample size calculator for statistical work.
SubShifter is an online tool that shifts the time stamps of SRT movie subtitle files to synchronize them with a video. It offers a Shift tool for a fixed offset and a Linear compensation tool for correcting time scale differences between subtitles and a movie.
The Borr Project offers a pre-college mathematics curriculum built from online materials, covering topics such as calculus, discrete mathematics, linear algebra and probability. Courses are chosen to match the 2015 CUPM Guide and be open for enrollment. The curriculum can be completed in about two years with roughly 18-22 hours per week, and students may work alone or in groups.
Ultimate Electronics Book is a free, interactive book for electronics hobbyists and electrical engineering students covering practical circuit design and analysis. Its table of contents lists chapters on conceptual foundations of engineering, linear direct current electronics, and op-amps, with several further sections marked as coming soon.
