Some concepts and methods of information granule diffusion

When a set of information granules is incomplete to represent an object A, it seems that we could employ the information diffusion techniques to change the granules into fuzzy granulations for filling the gaps with respect to a scarcity. In this paper, we suggest the concept of information granule diffusion, and give the 1-dimension linear diffusion model and normal diffusion model. We give two examples in engineering to show that the methods of information granule diffusion would play a pivotal role in the processing of incomplete, uncertain, vague information.
