Neural Network LSTM input shape from dataframe
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am trying to implement an LSTM with Keras . I know that LSTM's in Keras require a 3D tensor with shape (nb_samples, timesteps, input_dim) as an input. However, I am not entirely sure how the input should look like in my case, as I have just one sample of T observations for each input, not multiple samples, i.e. (nb_samples=1, timesteps=T, input_dim=N) . Is it better to split each of my inputs into samples of length T/M ? T is around a few million observations for me, so how long should each sample in that case be, i.e., how would I choose
