CS231N L1: Where Computer Vision Came From, and Where This Course Is Going
The first CS231N lecture of 2026 comes in two slide decks. The first tells the history of vision and deep learning on a single timeline: Hubel & Wiesel's cat experiments, Marr's stages of visual representation, then the Neocognitron, backprop, and LeNet, until ImageNet and AlexNet join the two threads. The second covers the course map, grading, and rules, and moves every assignment onto Colab. After this lecture you'll know which gap each of the remaining 17 lectures fills.
