A new approximation introduced elsewhere is employed to approximate the error associated with the central limit approximation. In particular, the respective error obtained on approximating a linear combination of n independently distributed random variables (Sn) is examined, and it is shown that the un...
Excess risk衡量的是训练模型的true error(population risk)和最优的true error(相对于全体可测函数而言,有时也称为Bayes error)的差距。Excess risk的分解: 假设全体可测函数中存在一个最牛的拟合器,我们叫它神谕拟合器(bayes optimal),Approximation error衡量的就是你的假设集和这个神谕拟合器的能力差距,主要度量...

3.2 Reduction of quantization error and suboptimality of the linear reconstruction The work on the noise reduction effect, reviewed in the previous subsection, was actually aimed at estimating quantization error, which is modeled as an additive white noise. However, results on reconstruction from quant...
Use the linear approximation (in 2 variables) to approximate the expression sin (1.03^2 + 0.96^2) - cos((1.03)(0.96)) Consider f(x) = \sqrt{x}, a = 4, n = 2, 4 \leq x \leq 4.1 (a) Approximate f by a Taylor polynomial...
