Recently, continual learning emerged as a rapidly growing area of machine learning where this assumption is relaxed, i.e. where the data distribution is non-stationary and changes over time. This paper represents the state of data distribution by a context variable $c$. A drift in $c$ leads to a data distribution drift.\n  A context drift may change the target distribution, the input distribution, or both. Moreover, distribution drifts might be abrupt or gradual.
