Description

The parameter r in our PeriodicKernel currently governs the size of the circle onto which the inputs are mapped. Would it not be more intuitive to parametrise it in terms of the frequency or period?

This might be a good opportunity to consider whether we actually need any parameters in the PeriodicKernel, since we can get everything that we need via transform, although we maybe want to ensure that that's wrapped for users.

Research direction

Start by locating the PeriodicKernel implementation and its transform entry point. Review how r controls the input mapping and whether transform already exposes the needed frequency or period behavior. Done means agreeing on the parameterization and providing a clear user-facing interface, including any needed wrapping for transform.
