β€’ Developed by Google

Detailed Explanation

TensorFlow is an open-source deep learning framework that was created by Google. This means that it is available for anyone to use, modify, and distribute, which allows a wide array of developers and researchers to contribute to its ongoing improvement.

Examples & Analogies

Think of TensorFlow as a set of tools in a toolbox for builders (developers and researchers) working on constructing a new type of building (deep learning models). Just as a variety of tools can help create different structures efficiently, TensorFlow provides various resources to help build robust machine learning models.

β€’ Symbolic computation graphs

Detailed Explanation

TensorFlow uses symbolic computation graphs to represent computations. In this context, a computation graph is a way to visualize the operations and dependencies between them. Each node in the graph represents an operation or a function, while the edges (arcs between nodes) represent the data, which is referred to as tensors. When you define a computation graph, you specify what computations you want to perform without actually executing them until you run the session.

Examples & Analogies

Imagine planning a recipe. The ingredients and the steps to combine them can be laid out in a flowchart. This flowchart is similar to a computation graph. You follow the steps (nodes), using ingredients (data) as you go, but you don't actually start cooking (executing the graph) until you're ready to prepare the dish (run the session).
