Keras is an open-source and high-level deep learning framework which is completely written in Python. An Artificial Intelligence researcher named Francois Chollet developed the Keras framework. Keras is capable of working with deep neural networks, but it cannot handle low-level computations. In that case, it uses its backend library. The backend library of Keras is so powerful that it works like a high-level API wrapper for low-level computations. 
The tutorial is mainly prepared for those interested in learning the Keras framework. In this tutorial, you will understand various concepts of Keras, including Keras modules, layers, models, and some topics related to deep learning as well. 

Audience:

So the tutorial is mainly designed for beginners as well as professionals who already have some basic understanding of Keras. However, anyone with a keen interest in learning this technology can be benefitted from this tutorial. 

Prerequisites:

As you are going to learn from this tutorial, some prerequisites might be useful for you. So, it's better to have a fundamental knowledge of some concepts that revolve around the Deep learning framework. Also, having knowledge of Python programming and Machine Learning will be a plus point for learners of this tutorial.
