micrograd++: A 500 line C++ Machine Learning Library Gautam Sharma Independent Researcher gautamsharma2813@gmail.com Abstract—micrograd++ is a pure C++ machine learning li- brary inspired by Andrej Karpathy’s Karpathy’s Python implementation of micrograd. This header only library aims to provide a simple yet powerful framework for building and training machine learning models. By leveraging the performance the first choice in that front. This library changes that by providing: • Modern C++ features: micrograd++ is written entirely in C++17. • Smart pointers: This library is memory safe. • Header only:
