Tangent

Tangent is an open-source project that provides a set of modular tools for automatic differentiation and machine learning research, primarily targeting developers and researchers who need fine-grained control over gradient computations. Its publicly-available modules allow users to define and differentiate arbitrary Python and NumPy code, making it interesting for its ability to bridge high-level frameworks with low-level, custom mathematical operations. This flexibility is valuable for prototyping novel algorithms or debugging complex models without being locked into a single library's autograd system.
