Fine-grained federation of geographic information services through metadata aggregation

Large scale Geographic Information Systems (GIS) require experts from different areas, such as data maintenance and handling, data rendering and displaying, and data processing. However, it is challenging to host data, processing capabilities, and experts in the same geographical location. To enable remote coupling of these data and processing services, interoperable distributed system architectures have been developed....

An examination of the effect of discretization on a naïve Bayes model's performance

A Bayesian network (or a belief network) is a probabilistic graphical model that represents a set of variables and their probabilistic independencies. Some researches often involve continuous random variables. In order to apply these continuous variables to BN models, these variables should convert into discrete variables with limited states, often two. During the discretization process, one problem that researchers...

The law of universal attraction with momentum exchange between objects and microparticles

The law of universal attraction has been used widely. However, how two objects attract each other is still a riddle. Hypotheses, such as gravitons, universal repulsion, sub-photon seas, etc., all have flaws, and do not deal with the basic reason why there is such a law. In this paper, suppose: (1) microparticles at a certain speed, moving like thermal motion of molecules, are distributed in space; (2) the objects are...
