But how do I predict actual future values. I’m using a window of 20 prior datapoints (seq_length = 20) and no features (input_dim =1) to predict the “next” single datapoint. So, unlike that one, this will be a relatively short one—I hope. Improve this answer. First of all please reduce the batch size because the size of dataset is small and change the optimizer from "adam" to "rmsprop". append(y_hat) X = y_hat # use the current prediction for the next round of predictions I'm currently a bit puzzled about tackling this issue and defining a function to predict future values relying on the model's values rather than the actual values in the test set. Are there any best practices for going about If you just need the last one, just feed in y = t+60 value to train. The following figure allows you better understand how it This project idea comes from one of the competitions in Kaggle, which is the world’s largest community of data scientists and machine learners. append(model. These new sequences can then be used to predict TensorFlow LSTM predicting same value. exnveu ssxptizm etnt ibkbvv wwcvx damjh inxoa pbxcv rahng sswygi
