In addition to well known problems associated with non stationary time series, machine learning models can not inherently deal with stochastic trends. As a result, their out of sample forecast accuracy will be "poor" if such trends are present.

AutoML Machine learning models can not inherently deal with stochastic trends, or other well-known problems associated with non-stationary time series. As a result, their out of sample forecast accuracy will be "poor" if such trends are present.

The first output of a non-stationary time series model might have data inconsistencies. When Automated ML detects and analyzes a time series dataset, the first output is differenced to mitigate the impact of having data inconsistencies.
