A note on the approximation of functions of several variables by sums of functions of one variable For a class of functions of several variables, which includes the continuous functions, we show that there exists a sum of functions of one variable that m... CT Kelley - 《Journal of Approxi...
Wavelets have been also used as basis functions to estimate the solutions of integral and differential equations. The approximation of a function belonging to some class by wavelet method has been discussed by many researchers like Devore [7], Morlet [11, 12], Meyer [10] and Debnath [6], ...
1.the process or result of making a rough calculation, estimate, or guess:he based his conclusion on his own approximation of the fuel consumption. 2.an imprecise or unreliable record or version:an approximation of what really happened.

More general, in the case of an orthogonal basis \\({\\left\\{{b}_{n}ight\\}}_{n\\in {\\mathbb{N}}_{0}}\\) , the series has the form 3.3 $$f ={ \\sum \\limits_{n=0}^{\\infty }}\\,\\left\\langle f, \\frac{1} {\\left\\|{b}_{n}ight\\|}\\,{b}_{...
从这个定理可以看出, K_n 充当了identity的职能, 于是\{K_n\}有时被叫做 an approximation to the identity. Proof~of~Theorem~4.1. 设\epsilon > 0, f 在x 连续, 则存在 \delta 使得|y|<\delta 推得|f(x-y)-f(x)| < \epsilon. 接下来, 由good kernel的第一条性质,...
The method used for the calculation of STF of S2 was published in Conclusion A method has been proposed for the calculation of the approximation of standard thermodynamic functions (STF). The approximation respects the physical properties of STF. This means that the approximation functions are, ...
Then it shows how to design the regular fuzzy neural networks (RFNNs) when the activation functions are the semi-linear sigmoidal function and the step function, respectively. After analyze the approximation accuracy of these two classes of RFNNs, it is found that the former has a much better...
