Machine Learning, Technical Debt, and You - D. Sculley (Google)

Machine learning offers a fantastically powerful toolkit for building useful complex prediction systems quickly. In this talk, we'll argue it is dangerous to think of these quick wins as coming for free. Using the software engineering framework of technical debt, we find it is common to incur massive ongoing maintenance costs in real-world ML systems. We explore several ML-specific risk factors to account for in system design. These include boundary erosion, entanglement, hidden feedback loops, undeclared consumers, data dependencies, configuration issues, changes in the external world, and a variety of system-level anti-patterns.  We then show how to pay down ML technical debt by following a set of recommended best practices for testing and monitoring needed for real world systems.
