Abstract: I will chart the history of Hilbert’s 13th Problem and connect it to recent theoretical research in neural networks and statistical regression. The focus will be a remarkable theorem of Kolmogorov and Arnold to the effect that continuous functions of many dimensions do not really exist. Specifically, any continuous function defined on the unit cube in N dimensions can be written as a continuous function of one variable acting on the sum N continuous functions of each of the coordinate variables separately. I will discuss where the problem came from, deep in the history of mathematics, and going back to the solution of polynomial equations, and how its solution might (or might not) be relevant to neural networks.
