AI Foundations
Understand what AI is, how systems learn, where they fail, and how to judge claims without hype.
Free AI library
1019 plain-English guides, structured learning paths, and an open library — built by an independent 501(c)(3) nonprofit so anyone can understand modern AI.

A point cloud is a set of 3D points (X, Y, Z) that captures the shape of real objects and spaces, often from LiDAR or depth sensors.
Visual AIA signed distance function (SDF) describes a 3D shape by telling you, for any point in space, how far it is to the nearest surface, with a sign that says…
TechnicalAn autoencoder is a neural network that learns to compress data into a compact code and then reconstruct it, forcing the network to capture only the most…
TechnicalSiamese networks use two or more identical, weight-sharing branches to learn how similar two inputs are, rather than classifying each one.
TechnicalMulti-task learning trains one model to perform several related tasks at once, sharing internal representations across them.
Audio AIMusic Information Retrieval (MIR) is the field that teaches computers to analyze, understand, and search music from audio signals and scores.
Audio AILearn how Demucs and HT-Demucs separate music into vocals and instrument stems using waveform, spectrogram, and transformer modeling.
Audio AIAudio chord recognition is the task of automatically labeling the chords played throughout a song directly from its audio.
CompaniesWeights & Biases is a developer platform for tracking, visualizing, and reproducing machine learning experiments.
CompaniesLangChain is an open-source framework (and company) for building applications powered by large language models.
CompaniesLlamaIndex is an open-source data framework that connects large language models to your private and external data.
TechnicalConformal prediction wraps any model to output a set or interval that is guaranteed to contain the true answer with a chosen probability, like 90%.
