• 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).
Key Concepts
