Since the value of the RBF kernel decreases with distance and ranges between zero (in the limit) and one (when {{math|'''x''' {{=}} '''x''''}}), it has a ready interpretation as a [[similarity measure]].<ref name="primer"/>
The [[feature space]] of the kernel has an infinite number of dimensions; for <math>\sigma = 1</math>, its expansion using the [[multinomial theorem]] is:<ref>{{cite arXiv
