Abstract: Disclosures teach providing data over a vehicle bus, data providing values for a road attribute indexed to points anticipated to be traversed by a vehicle. To compress the data, a server may fit a regression function to the data with coefficients applied to kernels in the function.

A client may maintain a copy of the kernels and retrieve the coefficients from the message. The client may estimate future values of the road attribute by evaluating the coefficients applied to the kernels, which may, in some examples, be Gaussian.
