The characteristics of dual tap filter and predictederror filter are analyzed, which are auto-adapted filters, and a numerical simulation is performed on computer.
对双向抽头滤波器和预测误差滤波器这两种自适应滤波器的特性进行了分析，并在计算机上进行了数值仿真。

The evaluation criterion is the root mean squared error (RMSE) between predicted ratings and true ones.
评判标准是预测打分和真实值之间的均方误差(RMSE)。

Dr Hill had predicted this outcome, thanks to error-management-theory-the idea that when people (or, indeed, other animals) make errors of judgement, they tend to make the error that is least costly.
