之后我们会执行 Fit Test 针对这个 theta^, 看看我们的估计好不好. 当然 Bayesian 估计中不一定使用 quadratic loss function 即 {theta – theta^}^2, 也可以使用 absolute error loss 或者 All or nothing loss. 我们发现了统计学中的MSE 是针对样本Xi的函数 来计算期望, 而贝兹估计中的MSE 却针对的是 在...
Is there a way to display the sum of square error in Matlab? What is the number displayed on the model output as a measure of best fit? When the data is presented following the estimation, it displays the loss function and the FPE. What is the FPE?

The least mean square (LMS) algorithm assumes a linear model of the form f(x)=θTx, with θ∈Rd, and a mean squared error loss function E(θ)=E[ei2] [1,2]. It is based on the stochastic gradient descent method, thereby, at each time instant ti,i=1,…,N, the instantaneous er...
梯度下降的中心思想是根据loss function上的点,在横坐标上移动,找到纵轴的最低点; 横坐标点的选取是由上一个点的梯度和学习率决定的,公式如下图; 纵轴最低点=该点梯度为0=学习率*梯度等于0=横坐标w不再变化; 李宏毅老师课程材料 - 机器学习 linear regression case study ...
