double log1p(const double x) { if (fabs(x) > 1e-4) { // x is large enough that the obvious evaluation is OK return log(1.0 + x); } return(x * (x * (2 * x - 3) + 6)) / 6; } 1. 2. 3. 4. 5. 6. 7. 8. 9. 这时有效数字提升到了12位,我们又前进了一步。 下...
The Taylor expansion of the real log function log(u) at u=1 is (u−1)−(u−1)2/2+…, so it is not surprising that there can be precision issues near 1. Moreover, for 1+2x+x2+y2 to be close to 1, 2x+x2+y2 must be small. And that implies that there must be ...

我需要用特定非线性函数(e^x or log(x) or log(1+e^x))的泰勒级数展开,对每个像素值进行非线性展开,但至少基于泰勒级数的概念,我目前的实现是不正确的。其背后的基本直觉是将像素阵列作为CNN模型的输入神经元,其中每个像素都应该用非线性函数的taylor级数展开来进行非线性展开。 新更新1 据我从泰勒级数的理解...

Independently of the RH, by looking at the behaviour of the convergent Taylor expansion of m(r) at r = 1-, the value m(r = 1/2+) as well as the first Li's coefficient may be evaluated using the Euler product formula. ... D Merlini - 《Chaos & Complexity Letters》 被引量: 12...
Next, observe that \(-\log g(-\rho )\) has the Taylor series expansion in the region \(0 {<} \rho {<} 1\) $$\begin{aligned} -\log g(-\rho ) = {\rho } + (1-\rho )\log (1-\rho ) = \frac{\rho ^2}{2} + \frac{\rho ^3}{6} + \frac{\rho ^4}{12} + ...
