1) Effective data discretization can obviously improve system ability on clustering instances, and can also make systems more robust to data noise. 2) In fact, any numerical discretization method has truncation error and there's no need to treat the difference equations as equality constraint. 3) Discretization of numeric attribute is an important role of data preprocessing. 4) An algorithm for discretization based on Particle swarm optimization (PSO) is presented, which can settle the problem of continuous attributes discretization in systema modeling perfectly. ? 5) In space discretization, a piecewise bilinear interpolation is used. THe integrals over patches are carried out analytically in closed form. 6) The former algorithm makes improvements from three aspects: discretization, reducing dimension, attribute selection, which effectively solves the conflict between efficiency and prediction precision. 7) Aiming at this situation, the continuous data discretization method based on Walsh transform was proposed. 8) This paper shows that the time discretization makes the lumped-mass method much better than the consistent-mass one as accuracy is concerned for simulating wave motion in the continuous model. 9) Otherwise, the latter has achieved the discretization for the continuous collision avoidance strategy by discrete logic. 10) The discretization and relevant numerical technique for the equation are briefly described. 11) The finite volume discretization method and treatment of boundary condition were presented. 12) In this paper a discretization algorithm based on importance of cut point. 13) Discretization can accelerate learning and simplify concluding knowledge,[http:///discretization.html] even improving sort precision. 14) In this paper a simplified recursion formula of discretization orthogonal polynomial in the case of uniform step is presented. 15) Focused on a posteriori error estimates for a finite volume discretization of an elliptic problem. 16) The sampling theorem is an important theorem in the stationary process, and discretization of the stationary process has theoretical and practical significance. 17) In the diagnosis of gas engine piston, the continuous data quantity is dispersed with the discretization algorithm to multiply or cut down the classes. 18) Focused on a posteriori error estimates a finite volume discretization of an elliptic problem. 19) In the second chapter, we present an additive Schwarz preconditioner for the rotated Q_1 finite element discretization of second order elliptic problem. 20) Attributes in the database of tumor diagnoses are usually quantitative attributes, so quantitative attribute discretization is a problem of mining association rules. 21) By introducing the concept of"nihility point"and the method of"spherule bounding" in the algorithm, we have simply and effectively realized boundary discretization in 3-D space. 22) One is Boolean sum approximation, the other is convex combination approximation, We still make discretization for two methods in an arbitrary triangle. Finally, a example is given. 23) Rough set theory has been successfully applied in data discretization. 24) Secondly, the system called the database to obtain the earthquake cases data including abnormal information and it is necessary to do some data preprocessing such as data discretization. 25) The method equivalent specific heat was adopted during the discretization of the non - linear equation of conduction. 26) Cartesian coordinate velocity is taken as the primary variable to simplify the discretization equation. 27) The unsteady supercavity shape and length is calculated by using the finite difference time discretization when cavitation number changes. 28) We propose a preconditioner based on the block diagonal matrices of SFVEM discretization system of 2-D three temperature radiation heat conduction equations.
