We Ran 35 Controlled Experiments on "Exotic Algebra" Neural Networks. They're a Placebo.
TL;DR: Quaternion, octonion, sedenion, and Clifford-algebra neural networks keep appearing in the literature with claims of parameter efficiency and special expressivity. We spent two months building them, benchmarking them — and honestly trying to make them win. Whenever we added one properly matched real-valued baseline, the advantage evaporated. Every time.
