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. WebDeepAR: Probabilistic forecasting with autoregressive recurrent networks which is the one of the most popular forecasting algorithms and is often used as a baseline Classes …
WebFeb 17, 2024 · DeepAR offers unique advantages, such as multivariate forecasts with multivariate inputs and scalability to thousands of covariates. The DeepAR model was benchmarked on realistic big-data scenarios and achieved approximately 15% improved accuracy relative to prior state-of-the-art methods.
