Improvement of Fusion Algorithm Based on Evidence Theory
Yi Chen, Gai-yun Wang, Bing Li · 2008
The relationship between basic probability assignment (BPA) and belief function in evidence theory is studied. The idea that belief function is regarded as BPA in data fusion is firstly introduced in this paper. An improved fusion algorithm based on distributed fusion method is put forward using this idea. The improved algorithm is called 'distributed fusion algorithm based on belief function assignment'. Through the experimental simulations to the traditional distributed fusion algorithm and the improved algorithm, the results show that the two algorithms are both valid in property identification.
