Radial basis function interpolation

Radial basis function interpolation is a type of math problem that can be used to find a smooth line or surface (like a curved bridge) that passes through a set of points. It can be used in a lot of different ways, like to predict the value of a point that isn't in the original set. Imagine that you have a bunch of dots on a piece of paper - the dots are like the points in the set. The radial basis function interpolation would draw a smooth line or curve that connected all the dots together.
