Modular Bayesian Network for Uncertainty Handling on Mobile Device
Keum-Sung Hwang, Sung-Bae Cho.
Mobile devices can now handle a great deal of information thanks to the
convergence of diverse functionalities. Mobile environments have already
shown great potential in terms of providing customized services to users
because they can record meaningful and private information continually for
long periods of time. Most of this information has been generally ignored
because of the limitations of mobile devices and the uncertainty of mobile
environments in real world. In this paper, we propose an approach based on
modular Bayesian networks to overcome these problems and to analyze various
kinds of log data. The method adopts a probabilistic approach to manage the
uncertainty and decomposes the probabilistic model automatically to decrease
complexity and how to infer the model, which is called cooperative reasoning.
In the experimental results, the proposed methods were evaluated with mobile
log data collected in the real world.
