Chebyshev wavelets method for boundary value problems

Chebyshev wavelets method (CWM) is applied to find numerical solutions of fifth and sixth order boundary value problems. Computational work is fully supportive of compatibility of proposed algorithm and hence the same may be extended to other physical problems also.  A very high level of accuracy explicitly reflects the reliability of this scheme for such problems. Key words: Chebyshev wavelets method (CWM),...

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...
