 The many models training component applies AutoML's [model sweeping and selection](concept-automl-forecasting-sweeping.md) independently to each store in this example. This model independence aids scalability and can benefit model accuracy especially when the stores have diverging sales dynamics. However, a single model approach may yield more accurate forecasts when there are common sales dynamics. See the [distributed DNN training](#distributed-dnn-training-preview) section for more details on that case.

 These steps are included in AutoML's transform pipelines, so they're automatically applied when needed at inference time. In some cases, the inverse operation to a step is included in the inference pipeline. For example, if AutoML applied a $\log$ transform to the target during training, the raw forecasts are exponentiated in the inference pipeline.
