40 Algorithms Every Programmer Should Know

Choosing sequential or functional model

The sequential model creates the ANN as a simple stack of layer. The sequential model is easy and straightforward to understand and implement, but its simplistic architecture also has a major restriction. Each layer is connected to exactly one input and output tensor. This means that if our model has multiple inputs or multiple outputs either at the input or output or at any of the hidden layers, then we cannot use a sequential model. In this case, we will have to use the functional model.
