Abstract:

The problem that whether there a theoretical limit exists for link prediction combination methods and how to approximate was investigated.Link prediction methods were divided into single or combination methods,based on whether multidimension information was used,or whether the relation of multidimension information was defined directly.Limit theorems for link prediction by approximating a measurable function by a simple function sequence were provided.Combination rule and corresponding geometric interpretations and simulation examples for limit theorems were also provided.Limit theorems show why combination methods have higher accuracy and robustness than single methods.

Key words: complex network, link prediction, combination method, theoretical limit
