Computation Graphs and Automatic Differentiation in Deep Learning Frameworks

Modern deep-learning stacks rely on a computation graph to represent a neural network as a directed acyclic graph (DAG) whose nodes are tensor operations and whose edges carry multi-dimensional arrays (tensors). This abstraction allows the framework to reason about the entire model ahead of time, insert missing backward operations, schedule ker ...

Forward vs. Reverse Mode Automatic Differentiation: When to Use Which

Automatic differentiation (AD) computes exact derivatives efficiently by applying the chain rule during program execution. Two primary strategies exist: forward mode and reverse mode. Their suitability depends on the shape of the function being differentiated—specifically, the number of inputs versus outputs. Intuitive Analogy: Manufacturing Wo ...
