What is TensorFlow
TensorFlow is a computational framework that manages complex numerical operations through dataflow graphs. Each node in the graph represents a mathematical operation, and each edge represents data in the form of tensors. This graph-based structure allows TensorFlow to execute computations in parallel, improving efficiency and scalability.
Originally released in 2015, TensorFlow was designed for research but has evolved into a production-grade platform used across industries. The framework supports both low-level and high-level APIs. Developers can build models using TensorFlow Core for full control or use Keras for faster prototyping and ease of use.
TensorFlow supports model development, training, optimization, and deployment within a single ecosystem. It integrates with tools like TensorBoard for visualization and TensorFlow Lite for mobile and embedded deployment.
