This involves first training the model on all available data and then saving the model to file. This means save the salient information learned by the model so that we do not have to re-create it every time a prediction is needed. Once the model is selected, we must finalize it. Finalize and Save Time Series Forecast Model This may not be the very best possible model we could develop on this problem, but it is reasonable and skillful. Predictions vs Actual Daily Female Birth Dataset Line Plot Rmse = sqrt(mean_squared_error(test, predictions)) Series = read_csv('daily-total-female-births.csv', header=0, index_col=0, parse_dates=True, squeeze=True) # Make a prediction give regression coefficients and lag obs # create a difference transform of the dataset We will take a look at each of these elements in this tutorial, with a focus on saving and loading the model to and from file and using a loaded model to make predictions.īefore we dive in, let’s first look at a standard univariate dataset that we can use as the context for this tutorial.įrom _model import AutoRegįrom trics import mean_squared_error Elements of the model are updated in the presence of new observations. The saved model is loaded and used to make a forecast. The chosen model is trained on all available data and saved to file for later use. This is where you choose a model and gather evidence and support to defend the decision. Once you can build and tune forecast models for your data, the process of making a prediction involves the following steps:
