Question
A large consumer goods manufacturer has the following products on sale:
- 34 different toothpaste variants
- 48 different toothbrush variants
- 43 different mouthwash variants
The entire sales history of all these products is available in Amazon S3. Currently, the company is using custom-built autoregressive integrated moving average (ARIMA) models to forecast demand for these products. The company wants to predict the demand for a new product that will soon be launched. Which solution should a Machine Learning Specialist apply?
Options
- ATrain a custom ARIMA model to forecast demand for the new product.
- BTrain an Amazon SageMaker DeepAR algorithm to forecast demand for the new product.
- CTrain an Amazon SageMaker k-means clustering algorithm to forecast demand for the new
- DTrain a custom XGBoost model to forecast demand for the new product.

Explanation
The 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. They then use that model to extrapolate the time series into the future. https://docs.aws.amazon.com/sagemaker/latest/dg/deepar.html
