Course Notes Archive

This archive preserves course notes, assignments, exam reviews, and project records from my undergraduate and graduate studies. Unlike the curated Algorithms, AI Systems, CS Foundations, and Software Engineering maps, these pages follow the chronology and vocabulary of individual courses.

Course Notes Archive

Semester notes, kept in the order and vocabulary they were studied.

These pages preserve how the material was originally studied, so they may mix English and Chinese and keep grades, schedules, and administrative details as historical records. For a topic-centered explanation, start from the curated knowledge maps instead.

How to Use This Archive

• Use each course overview as the map for its lectures, assignments, projects, and exam material.
• Treat grades, schedules, and administrative details as historical records rather than current course policy.
• Follow links into the curated knowledge base when you want a topic-centered explanation rather than semester notes.
• Course pages may mix English and Chinese because they preserve how the material was originally studied.

Knowledge Maps

For polished, continuously maintained material, start with:

• Algorithms for problem-solving patterns and data structures;
• AI Systems for machine learning, foundation models, evaluation, and production AI;
• CS Foundations for operating systems, networks, and system design;
• Software Engineering for languages, data systems, delivery, testing, and operations.
