二. Root Mean Squared Error的MindSpore代码实现 我们来看一下代码,代码比较简单,在此我们没有metric的实现,实现的是loss的代码。 Root Mean Squared Error的Loss代码实现 importmindsporeimportmindspore.common.dtypeasmstypefrommindspore.common.tensorimportTensorfrommindspore.common.parameterimportParameterfrommindspore.o...

RMSE = √(Σ(yi - f(xi))^2 / M)其中，yi和f(xi)分别为第i个样本的实际值和预测值，M为样本总数。RMSE基于均方误差（MSE）计算，深入了解MSE概念请参考另一篇文章。在MindSpore中，实现RMSE代码相当简洁，无须专门实现metric，主要关注loss的计算。以下是代码示例：代码示例如下，直观展示RMSE计...
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...

Accepts the loss on a dispute. Square returns the disputed amount to the cardholder and updates the dispute state to ACCEPTED. Square debits the disputed amount from the seller’s Square account. If the Square account does not have sufficient funds, Square debits the associated bank account. Add...
We derive the mapping between two of the most pervasive utility functions, the mean square error ( MSE MSE ) and the concordance correlation coefficient (CCC, ho_c ho_c ). Despite its drawbacks, MSE MSE is one of the most popular performance metrics (and a loss function); along with lat...
