Summary

svmjs Andrej Karpathy July 2012 svmjs is a lightweight implementation of the SMO algorithm to train a binary Support Vector Machine. As this uses the dual formulation, it also supports arbitrary kernels. Correctness test, together with MATLAB reference code are in /test. Online GUI demo Can be found here: http://cs.stanford.edu/~karpathy/svmjs/demo/ Corresponding code is inside /demo directory. Usage The simplest use case: Here, data and testdata are a 2D, NxD array of floats, labels and testlabels is an array of size N that contains 1 or -1. You can also query for the raw margins: The library supports arbitrary…

What This Teaches

• How earlier vision and captioning systems connect representation learning with language outputs.
• Useful historical context for multimodal LLM research and evaluation.

Why It Matters

This matters as part of Karpathy’s broader pattern: compress hard technical systems into readable, inspectable, working artifacts.
