Deep learning is a topic of considerable interest today. Since it deals with estimating -- or learning -- models, there are connections to the area of System Identication developed in the Automatic Control community. Such connections are explored and exploited in this contribution. It is stressed that common deep nets such as feedforward and cascadeforward nets are nonlinear ARX (NARX) models, and can thus be easily incorporated in System Identication code and practice. The case of LSTM nets is an example of NonLinear State-Space (NLSS) models.
