The REGR_COUNT function returns the number of non-null number pairs used to fit the regression line. The REGR_INTERCEPT function returns the y-intercept of the regression line ("b" in the equation y = a * x + b). The REGR_R2 function returns the coefficient of determination ("R-square...
control function regression 控制函数法 控制函数怎么找 随着软硬件的飞速发展,计算机技术已经广泛地应用到自动化控制领域,为了实现实时控制,控制程序必须能够精确地完成定时和计时功能。VC提供了很多关于时间操作的函数,下面根据它们精度的不同,分别进行说明。 一般时控函数 VC程序员都会利用Windows的WM—TIMER消息映射来进...

好了,做完这一系列的准备工作,我们可以进入正题了,即用function-space的角度去导出我们的GPR。 首先考虑一个一般的带噪声的的回归模型 y=f(\bm{x})+\varepsilon,其中核心部分来自一个给定mean function和covariance function形式,但是参数待定的高斯过程f(\bm{x}) \sim \mathcal{GP}(\mu,k), 另外其中的噪声...
