2022. 5. 7. · GluonTS simplifies the time series modeling pipeline by providing the necessary components and tools for quick model development, efficient experimentation and evaluation. In addition, it contains reference implementations of state-of-the-art time series models that enable simple benchmarking of new algorithms.

GluonTS models will need to “serialized” (a fancy word for saved to a directory that contains the recipe for recreating the models). To save the models, use save_ gluonts _model(). Provide a directory where you want to save the model. This saves all of the model files in the directory. Note that N-BEATS models can be VERY LARGE. To illustrate how to use GluonTS, we train a DeepAR-model and make predictions using the simple "airpassengers" dataset. The dataset consists of a single time-series, containing monthly international passengers between the years 1949 and 1960, a total of 144 values (12 years * 12 months).
