In this paper, a Bayesian dynamic model is proposed to evaluate the sensor nodes' credibilities online, in a paradigm of agricultural Internet of things (IoT). The purpose is to discriminate reliable and unreliable data items before further data analysis, and thus to implement reliable data analysis. The credibility of the sensor node of interest is treated as the state variable of the model. The...
This paper studies on how to improve the efficiency of multilayer relationship checking, which was the most complex and time-consuming operation in land plan spatial data quality checking. The existing researches on spatial data quality mostly focused on how to evaluate spatial data quality, but few studies on efficiency. With an in depth study on the characteristics of multilayer relationship, we...
In this paper, we explore whether the functional magnetic resonance imaging(fMRI) signals of advanced brain areas except the motor area, prefrontal brain regions can be used in the brain-computer interface and how to effectively improve the accuracy of thinking classification by extracting blood oxygen level dependent(BOLD) signal features. We focus on whether the fMRI brain signal of posterior parietal...
