求翻译：We usually use RMSE to represent the deviations between predictions and atual ratings. RMSE is defined as the squared root of the sum of squared errors at each known user item ratings. So our matrix factorization target could be mathmatically defined as:是什么意思？ 待解决

我们通常用均方根误差来表示预测和atual收视率之间的偏差。

我们通常使用RMSE代表在预言和atual规定值之间的偏差。RMSE被定义，平方和的方根在每个已知的用户项目规定值的错误。因此我们的矩阵工厂化目标能mathmatically被定义如下：

我们通常使用 RMSE 表示预测和双流额定值之间的偏差。RMSE 被定义为在每个已知的用户项评级的平方误差的总和的平方根。所以我们的矩阵分解目标可能是矩定义为：

我们通常使用 RMSE 代表预言和 atual 等级之间的偏离。RMSE 在每项已知用户条款被定义为总和被弄成直角的错误的被弄成直角的根本等级。这样我们的矩阵因子分解目标可能是 mathmatically 被定义为：
