Keras focuses on debugging speed, code elegance & conciseness, maintainability, and deployability. Contrast this with a classification problem, where the aim is to select a class from a list of classes (for example, where a picture contains an apple or an orange, recognizing which fruit is in the picture). This is so that the data is re-interpreted using row-major semantics (as opposed to R’s default column-major semantics), which is in turn compatible with the way that the numerical libraries called by Keras interpret array dimensions. The returned states can be used to resume the RNN execution later, or to initialize another RNN.
