Machine Learning Systems: Detailed Course Description

📚 Course Overview

Machine Learning Systems is a systematic textbook on machine learning engineering, originating from Harvard University's CS249r course, taught by Professor Vijay Janapa Reddi. It is an open-source, continuously updated online textbook, slated for official publication by MIT Press in 2026.

Core Features

  • Systematic Perspective: Unlike resources that focus solely on algorithms and model architectures, this course emphasizes the overall context in which machine learning systems operate.
  • Theory and Practice Combined: Connects theoretical foundations with practical engineering applications.
  • Full Lifecycle Coverage: From data engineering, model optimization, and hardware-aware training to inference acceleration.
  • Open-Source Collaboration: Fully open-source, continuously updated, and community-driven.

🎯 Learning Objectives

This course is designed based on Bloom's Taxonomy of Educational Objectives, covering six levels of learning:

  1. Remembering: Recalling basic facts and concepts.
  2. Understanding: Explaining ideas or processes.
  3. Applying: Using knowledge in new situations.
  4. Analyzing: Breaking information into component parts.
  5. Evaluating: Making judgments based on criteria.
  6. Creating: Combining elements into a coherent whole.

💡 Core Philosophy

This textbook stems from a concern: While students are eager to train AI models and become AI programmers, few understand how to build the systems that truly make these models work. As AI becomes more powerful and autonomous, the critical bottleneck will not be the algorithms themselves, but the AI engineers capable of building efficient, scalable, and sustainable systems that safely harness this intelligence.

This is not merely a static textbook, but a dynamic, evolving learning resource designed to keep pace with the advancements in the field of machine learning systems.
