Running a Neural Network on a Calculator: A 56-Hour Train Journey
2025-01-04
A computer science PhD challenged himself to port a convolutional neural network (CNN) to a TI-84 Plus CE graphing calculator during a 56-hour train ride. Overcoming significant hardware limitations, including scarce memory and the lack of native floating-point operations, he successfully trained and ran the network to identify handwritten digits. While slow, the accomplishment demonstrates the feasibility of running AI on severely resource-constrained devices, showcasing ingenious memory management and algorithmic optimizations.
