TensorBoard is an open-source tool developed by the TensorFlow team for monitoring and visualizing machine learning experiments. It’s primarily used during model development to track training metrics, visualize computation graphs, and compare experimental runs. Though it is deeply integrated with TensorFlow, TensorBoard can also be adapted to work with other frameworks through custom logging.

It is designed for machine learning researchers, engineers, and developers who need transparent insights into model behavior, convergence, and performance over time. TensorBoard is lightweight, easy to integrate, and widely used in both academic and production settings.

Key benefits:

• Intuitive real-time visualization of training progress and metrics

• Facilitates debugging, optimization, and experiment comparison

• Compatible with TensorFlow and other frameworks via manual logging
