Let us now consider one training stepn, where the neural network\({G}_{{\theta }_{n}}\)has weights obtained from the previous training steps (or randomly initialized if this is the first step). We need to solve the IE $${\bf{y}}=f(t)+\mathop{\int}\nolimits_{\!\alpha (t)...
\int \frac{\cos (\theta-1) d \theta}{\sin ^{2}(\theta-1)}=? ,令 t=\sin (\theta-1) ; …… 可能有些人觉得这样写 t=\square 太麻烦了,明明可以直接写的。当然,如果我们很熟练我们就可以直接写,比如: \int(3 x+1)^{5} d x=\frac{1}{3}\int (3x+1)^5d(3x+1)=\frac{1}{...
2 x ^2 d x Evaluate the integral. \int_{0}^{\pi/4}\textrm{tan}^3 \theta \; \textrm{sec}^2 \theta \; d \theta Evaluate the integral \int_0^5 \int_0^4 (18x + 4y)dxdy. Evaluate the integral: ( 3 x 3 2 x + 3 ) d x ...
\int_{C_R}f(z)dz=\int_0^\pi \frac{1}{(R^2e^{2i\theta}+1)^2}iRe^{i\theta}d\theta \\ 有不等式 |R^2e^{2i\theta}+1|\geq |R^2e^{2i\theta}|-1=R^2-1 \\ 当R>1时|e^{i\theta}|<R,则有不等式 \begin{aligned} |\int_{C_R}f(z)dz| &\leq\int_0^\pi |\fr...
