Keras is an accessible and versatile open-source deep learning framework that simplifies the process of building and training neural networks. It offers a user-friendly, high-level API for defining complex neural network architectures with ease. Keras promotes modularity, allowing users to stack layers and customize network structures to suit their specific needs. Its compatibility with popular deep learning libraries like TensorFlow and Theano ensures access to a vast ecosystem of tools and resources. With applications spanning image classification, natural language processing, speech recognition, and more, Keras is a valuable tool for both beginners and experienced deep learning practitioners, facilitating rapid prototyping and experimentation in the development of sophisticated machine learning models.

Keras and TensorFlow are two integral components of the deep learning landscape. TensorFlow, developed by Google, is a versatile open-source machine learning framework known for its scalability and flexibility. It offers a comprehensive ecosystem for machine learning model development and deployment, supporting tasks across the AI spectrum. Keras, on the other hand, is a high-level API for building neural networks that was originally standalone but has been seamlessly integrated into TensorFlow since version 2.0. Keras is celebrated for its simplicity and user-friendliness, providing an intuitive interface that simplifies the creation and training of neural network models. This integration allows users to leverage TensorFlow's power and performance while benefiting from Keras' ease of use, making it a preferred choice for both beginners and experienced deep learning practitioners.
