Qualitative Bayesian Networks with Weight
MA Xi-jun · Journal of Chinese Computer Systems · 2007
Qualitative signs are used in qualitative Bayesian network to express various influences among variables, but the strengths are not indicated. In this paper, we study on qualitative Bayesian networks with weight. A weight is a numerical value in[0, 1] to show the strength of influence. The operation rules used in network reasoning are revised. And we design a weight pole, which can help experts educe weights. This method keeps the simplicity of modeling process and improves the precision of reasoning.
