At one time or another, you've probably used spreadsheet programs to find the best linear equation that fits a given set of data points — an operation called simple linear regression. If you've ever wondered exactly how the spreadsheet program completes the calculation, then don't worry, it...
Thus, we obtain the average number of additions in Example 1 as 21−𝐶∑𝑖=1𝐶−1(𝐶−1𝑖)(𝑖−1)=𝐶−32+21−𝐶 (3) for 𝐶>2. For 16-bit signed integer arithmetic, we need approximately 6.5 additions per multiplication. The multiplication of a 4096×512 ...
Example 1. Let x ∈ R 𝑥∈ℝ have unit variance and f ( x ) = t x , t ∈ [ − 1 , + 1 ] 𝑓(𝑥)=𝑡𝑥,𝑡∈[−1,+1]. Let the computation encoding take the form m ( x ) = sign ( t ) ∑ b = 1 C − 1 c b 2 b − C x (1) where the coef...
However, no one finds an example of weakly regular plateaued balanced functions in the set WRPB . It would be desirable to find such a function, but we have not been able to do this. Author Contributions Conceptualization, S.Y. and T.Z.; methodology, S.Y.; validation, S.Y., T.Z....
However, in practical data analysis, we may not know the true model structure and can use nonparametric regression models to fit the nonlinear relationships of the variables in the data, but when the dimensionality of the covariates is large, such models can create the problem of “dimensional ...
(a) Static load measurement results; (b) regression line plot. 4.3. Grinding Force Measurement The home-made workpiece with an installed load cell to measure the grinding force was then used to perform the grinding process. Figure 11 shows the surface of the workpiece before and after the ...
Variable selection in high-dimensional partially linear additive models for composite quantile regression. Comput. Stat. Data Anal. 2013, 65, 56–67. [Google Scholar] [CrossRef] Wu, Q.; Zhao, H.; Zhu, L.; Sun, J. Variable selection for high-dimensional partly linear additive Cox model ...
Before we turn to extensions of the SUSY formalism to equations different from the TDSE, let us now give an example of how our SUSY formalism can be applied. We consider the special case (64), that is, the TDSE for weighted energy: i h ψ t + ψ x x − V 1 ψ = 0 , (68...
For example, the standard Cauchy matrix 𝐶=[1/(𝑥𝑖−𝑦𝑗)]C=[1/(xi−yj)] with real vectors x and y is equal to 𝐶(𝑥,𝑦,𝑒,𝑒)C(x,y,e,e), where 𝑒=[1…1]𝑇e=1…1T. Clearly, given generators, all elements of a Cauchy-like matrix can be computed...
