Key Features of TensorFlow

Graph-based computation

TensorFlow represents computations as directed acyclic graphs (DAGs) to optimize performance and enable distributed computing. This graph-based approach allows for efficient parallelization and makes it easier to reason about the flow of data and computations within a neural network. The DAG structure ensures that operations are executed in a specific order, with each operation producing a tensor (a multi-dimensional array) as output. These tensors can then be passed as input to subsequent operations, forming a hierarchical structure that captures the computational graph of the neural network.

Automatic differentiation

TensorFlow's ability to automatically compute gradients makes it easier to train neural networks using gradient-based optimization algorithms. Automatic differentiation (autodiff) is a technique that allows TensorFlow to compute the gradient of a function with respect to its inputs by recursively applying the chain rule of calculus to the mathematical expression representing the function. This enables the backpropagation algorithm, which is widely used for training neural networks, to efficiently compute the gradients of the loss function with respect to the model parameters. By computing gradients with respect to the parameters, TensorFlow can update the parameters using gradient descent or other optimization algorithms to minimize the loss function and improve the network's performance.
