A retail store plans to use Amazon SageMaker DeepAR to forecast demand for a product over the coming weeks. Which type of input data is required for this forecasting task?

Amazon SageMaker DeepAR is an algorithm specifically designed for forecasting time series data. It uses recurrent neural networks (RNNs) to learn patterns from historical time series and predict future values. Therefore, the required input data for DeepAR must be in a time series format, meaning data points are indexed in time order. Text data and image data are not suitable for DeepAR as they represent different data types and require different machine learning models (e.g., natural language processing for text, computer vision for images). Binary data refers to data with only two possible values (e.g., 0 or 1) and is not inherently a forecasting input type.
