AutoDiff: A Comprehensive C++ Framework for Automatic Differentiation

Version 1.0.0 - First stable release of our high-performance automatic differentiation framework

Overview

AutoDiff is a modern C++ library that provides efficient and accurate automatic differentiation capabilities for scientific computing, optimization algorithms, and machine learning applications. This framework supports both forward and reverse mode differentiation, allowing users to choose the most efficient approach for their specific use case.

Key Features

• Dual Differentiation Modes:

  • Forward Mode: Optimized for functions with few inputs and many outputs
  • Reverse Mode: Efficient for functions with many inputs and few outputs

• Comprehensive Elementary Function Support:

  • Trigonometric and inverse trigonometric functions
  • Hyperbolic and inverse hyperbolic functions
  • Exponential and logarithmic functions
  • Error functions (erf, erfc)
  • Gamma functions

• Expression System:

  • Intuitive representation of mathematical expressions
  • Seamless composition of complex functions
  • Automated application of calculus rules (chain, product, quotient)

• Performance Optimizations:

  • Constant propagation and folding
  • Common subexpression elimination
  • Algebraic simplifications

• Advanced Features:

  • Control flow differentiation (loops and conditionals)
  • Custom function registration
  • Memory-efficient computation

Performance Highlights

• Forward mode shows exceptional performance for elementary operations (~0.18 ns)
• Reverse mode efficiently handles multi-variable gradient computations
• Memory overhead is carefully managed for performance-critical applications

Documentation

Comprehensive documentation is available in the repository, including:

• Architectural overview
• API documentation
• Usage examples
