TensorFlow is a powerful open-source framework for machine learning and artificial intelligence, developed by the Google Brain team. It provides a comprehensive ecosystem of tools and libraries that facilitate the design, training, and deployment of machine learning models, particularly deep learning models. TensorFlow supports both CPU and GPU computations, making it scalable and efficient for large datasets. Its flexible architecture allows developers to build and train complex neural networks, while its high-level APIs, such as Keras, simplify model creation and experimentation. TensorFlow is widely used in various applications, including image and speech recognition, natural language processing, and reinforcement learning.
