WebThe Amazon SageMaker DeepAR forecasting algorithm is a supervised learning algorithm for forecasting scalar (one-dimensional) time series using recurrent neural networks (RNN). Classical forecasting methods, such as autoregressive integrated moving average (ARIMA) or exponential smoothing (ETS), fit a single model to each individual time series. WebFeb 14, 2024 · Especially for such time series as in the example - i.e. without trends and with rare/low swings, the Naive Algorithm is a popular prediction method precisely because of its trivial model.
