For a description of possible hints, refer to the docstring of sympy.integrals.transforms.IntegralTransform.doit(). Note that for this transform, by default noconds=True. >>> from sympy import cosine_transform, exp, sqrt, cos >>> from sympy.abc import x, k, a >>> cosine_transform(exp...
Calculate the following integral: int x^3 exp(5x^4) dx Find the integral by integration by parts or a substitution. Integral of xe^(x^2) dx. Compute the integral.\\int_1^2 \frac{3x}{\sqrt[4] {2x^2 + 7 dx Calculate the integral. \int_{0}^{3} \frac{1}{\sqrt{9+x^2 d...
由于exp上面的部分可以理解成拉格朗日量的积分，也就是作用量\lim_{\Delta t \rightarrow 0} \sum_{j = 0}^{t/\Delta t} (\frac{m}{2} (\frac{x_{j+1} - x_j}{\Delta t})^2 - V(x_j)) = \int_0^t ds (\frac{m}{2} \dot{x}(s)^2 - V(x(s))) = \int_0^t ds L(...

so you only have to integrate a scalar function of x. As Walter pointed out, in general it's better to use G = F*( (exp(i*x)*I-A-B*F)\B ) instead of inv, but for a 2x2 it probably doesn't matter too much. 추가 답변 (0개) ...
之前写过一篇ICCV 2021的《Removing the Bias of Integral Pose Regression》论文笔记,讲述如何用数学方法对Soft-Argmax引入的误差进行修正,并通过调整平滑系数来改善Soft-Argmax准确度。 文中的方法直接通过数学公式得出了修正方案,可以直接对IPR的结果减去误差项,十分简洁直观,所以我也第一时间尝试了复现。

The solution of the path integral for this process is a well known result, and it can be cast in the form 12 where Iharmonic(x, T | y, t) = eω(x2−y2)/2σ2 e−ω(T −t)/2 √1 2πσ¯2 exp − (y e−ω(T −t) 2σ¯2 − x)2 , σ¯ = σ (...
We calculate more generally for $ b_1\\geq 0,\\ldots b_n\\geq 0$ the integral $$GSTZ_n=\\int \\exp \\left(-\\-\\frac{1}{2}b^*M_x^{-1}bight)(\\det M_x)^{-1/2}dx,$$ we show that it leads to a natural family of distributions in $\\R^n$, called the $GST...
