The first part of the piecewise function is a quadratic expression. The domain of a quadratic expression is the set of all real numbers since no value in x can be excluded. However, notice that the function is quadratic for all values less than -1. If {eq}x=-1 {/eq}, examine the ...
Real-life signals can be modeled as functions of bounded variation.Thus the variable knot of approximating function could be self- adaptively chosen by balancing the totalvariation of the target function. In this paper, we adopt continuous piecewiselinear approximation instead of the existing piecewise...
The method is illustrated and it is explained how to calculate the survivor function from a censored data set. The estimator is compared with the well-known Kaplan-Meier estimator, using a set of data observed in a real engineering situation. The advantages and disadvantages of the method are ...
aa new augmented Lagrangian function with 4-piecewise linear NCP function is introduced for the solution of nonlinear programming problems with equality constrained and inequality constrained 一个新的被增添的Lagrangian作用以4-piecewise线性NCP作用为非线性规划问题的解答被介绍以拘束的平等拘束的和不平等 [...
In our approach, multiple radial basis function (RBF) neural predictors are used to model the piecewise dynamic in different partition intervals. Switching between different intervals could be estimated by a nonlinear gate model. In particular, a GA is employed here to train the MM and to obtain...
The reconstruction of images is an important operation in many applications. From sampling theory, it is well known that the sine-function is the ideal interpolation kernel which, however, cannot be used in practice. In order to be able to obtain an acceptable reconstruction, both in terms of...
Normally, a fine-scale representation of the level-set functions is used, yielding a high number of degrees of freedom in the estimation. In contrast, we focus on reparameterization of the level-set functions on a coarse scale. The number of coefficients in the discretized function is then ...
A sequential testing approach to detecting multiple change points in the hazard function using likelihood ratio statistics and resampling is proposed, which is applicable to both right-censored and interval-censored data. Numerical results based on simulated survival data and a real example show that ...

In this paper, we aim to obtain a dense piecewise planar reconstruction of the scene from multiple image frames based on a factorization framework. Integrating all the relevant constraints in a global objective function, we are able to effectively leverage on the scene smoothness prior afforded by...
