在本教程中,我们将使用PyTorch-LSTM进行深度学习时间序列预测。 我们的目标是接收一个值序列,预测该序列中的下一个值。最简单的方法是使用自回归模型,我们将专注于使用LSTM来解决这个问题。 数据准备 让我们看一个时间序列样本。下图显示了2013年至2018年石油价格的一些数据。
x_train_multi, y_train_multi = multivariate_data(dataset, dataset[:, 1], 0, TRAIN_SPLIT, past_history, future_target, STEP) x_val_multi, y_val_multi = multivariate_data(dataset, dataset[:, 1], TRAIN_SPLIT, None, past_history, ...

The spatial characteristics of multivariate time series variables are extracted from the CNN convolution layer and then passed on to the LSTM layer after extracting the representative features from the input data. The LSTM layer models the irregular time information using the transmitted spatial features...
基于Pytorch的LSTM模型对股价的分析与预测随着金融市场的不断发展,对股票价格预测的准确性成为了许多人的焦点。传统的股价预测方法通常基于历史数据和统计分析,但这些方法的预测效果并不理想。近年来,随着深度学习技术的兴起,越来越多的研究者将深度学习模型应用于股票价格预测。其中,长短期记忆网络(LSTM)是一种适用于序...
