Abstract
Examples of methods for determining an adaptive thermal diffusivity kernel are described herein. In some examples, an adaptive thermal diffusivity kernel is determined based on a map. In some examples, a temperature is predicted based on the adaptive thermal diffusivity kernel. In some examples, the map includes a temperature map, a shape map, or a concatenation of the temperature map and the shape map.
