Understanding the Keras Library

Keras is a high-level neural networks API that provides an easy-to-use interface for building and training deep learning models. It is built on top of other popular deep learning frameworks, such as TensorFlow, Theano, and Microsoft Cognitive Toolkit (CNTK), and provides a simpler and more user-friendly interface for building and training models. The main problem domain that Keras solves is the complexity and verbosity of building and training deep learning models using low-level frameworks such as TensorFlow and Theano. Keras provides a consistent and simple API that makes it easy to build and train models, and it abstracts the low-level details of the underlying framework. This makes it a great choice for beginners who want to get started with deep learning quickly and easily.
