Design Patterns in Machine Learning Code and Systems

Design patterns are not just a way to structure code. They also communicate the problem addressed and how the code or component is intended to be used. Here are some patterns I've observed in machine learning code and systems, mostly from the Gang of Four design patterns book. Most developers have some familiarity with these patterns and having a basic understanding provides a shared vocabulary to discuss ideas on design and implementation. The factory pattern decouples objects, such as training data, from how they are created.
