最近的一个发展是rsample包,它使交叉验证抽样计划非常易于实施。此外,rsample包还包含回测功能。“Time Series Analysis Example”描述了一个使用rolling_origin()函数为时间序列交叉验证创建样本的过程。我们将使用这种方法。 4.1 开发一个回测策略 我们创建的抽样计划使用 50 年(initial= 12 x 50)的数据作为训练集...
Enough of the preliminaries, let's see how LSTM can be used for time series analysis. Predicting Future Stock Prices Stock price prediction is similar to any other machine learning problem where we are given a set of features and we have to predict a corresponding value. We will perform the...
