Machine learning systems represent inherently complex engineering challenges. However, they are constructed from fundamental building blocks that must be thoroughly understood before advancing to sophisticated implementations. This pedagogical approach parallels established educational progressions: students master basic algorithms before tackling distributed systems, or develop proficiency in linear algebra before engaging with advanced machine learning theory. ML systems similarly possess essential foundational components that serve as the basis for all subsequent learning.
