NN Visual is an interactive web-based neural network visualizer. It lets users configure hidden layers, select datasets such as auto_mpg, iris, xor, or mnist, and train a network while observing forward and backpropagation step by step. The tool displays training loss, mean absolute error, weight distributions, and node activation brightness. Written explanations accompany the visualizations to teach concepts like gradient descent, weights, biases, and activation functions without requiring code.
Protocol and API documentation for Tor relay and bridge status data used by network tools.
OONI, the Open Observatory of Network Interference, is a global community measuring internet censorship. OONI Probe tests the blocking of websites and apps and measures network speed and performance, while OONI Explorer displays censorship data collected from over 200 countries since 2012.
Peek is a browser tool project hosted on GitHub that allows users to preview documents, videos, music and other content in their browser by hovering the mouse over relevant links.
pgmpy is a Python toolkit for causal and probabilistic reasoning using graphical models. It implements data structures for models such as DAGs, PDAGs, MAGs, PAGs, Bayesian Networks, Dynamic Bayesian Networks and Structural Equation Models, with algorithms for tasks including causal discovery, causal identification, inference, model validation, parameter estimation and simulations. Algorithms follow a unified composable API and are scikit-learn compatible when possible. It is available on PyPI and conda.
Pi-hole is a network-wide ad blocker installed in one place so every device on a network is protected. It runs in Docker or on a supported Linux distribution and is used as a DNS server, with a web interface, built-in DHCP server, group management and allow/deny domain rules. Pairing it with a VPN extends protection on mobile data and public Wi-Fi.
