Step 1: Sketch constraint functions (Eqs 3.38b and 3.38c) and side constraints (Eq. 3.38d) on the design plane of two design variables, x1 and x2. Step 2: Identify the feasible region, in which any point in the region satisfies the constraints. Step 3a: Sketch iso-lines of the objec...
Linear regression models are fitted in RevoScaleR using the rxLinMod function. Like other RevoScaleR functions, rxLinMod uses an updating algorithm to compute the regression model. The R object returned by rxLinMod includes the estimated model coefficients and the call used to generate the mo...
In the next step, the test functions are defined, and the test functions and their required gradients are computed at the interior and boundary points: # test functions vx_x_interior, vy_x_interior = self.v.eval_test("vx", x_interior, y_interior) vx_y_interior, vy_y_interior = self...

The details can be found, for example, in [9,15]. From the definition of the homographic transformation it is clear that X=Hm(I,X). On the basis of this property and Lemma 2.6, it can be further proven that if the matrix Φ is invertible, then from Y=Hm(Φ,X) we can get X=...
=== There are some large data for which with/without nonlinear mappings gives similar performances. Without using kernels, one can efficiently train a much larger set via linear classification/regression. These data usually have a large number of features. Document classification is an example...

This fact only highlights the importance of the zero model; without it, the R2 of all models might have seemed satisfactorily high. In comparison to the zero model, however, it becomes clear that a simple 1-lag linear model, for example, has in fact a very low predictive power. The ...
Bozga, Iosif and Konecný’s FLATA tool [13] considers affine functions in arbitrary dimension. However, it is restricted to affine functions with finite monoids; in our one-dimensional case this would correspond to limiting oneself to counter-like functions of the form. ...
In this paper, we introduce the notion of a self-regular function. Such a function is strongly convex and smooth coercive on its domain, the positive real axis. We show that any such function induces a so-called self-regular proximity function and a corresponding search direction for primal-...
