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 x=−1, examine the domain of ...
Page 1 of 2 2.7 Piecewise Functions GOAL 1 REPRESENTING PIECEWISE FUNCTIONS What you should learn GOAL 1 Represent Up to now in this chapter a function has been represented by a single equation. In piecewise functions. many real-life problems, however, functions are represented by a combination...
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...
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 ...

Our problem differs from these as we model changes in slope rather than fitting a step function to the mean, and we consider multiple time series with replication. For a given period t = 1, …, T we observe multiple time series which are assumed independent, each one consisting ...
