Notes
1 Why This Page Matters
Notes are often the best format when you already know the topic name and want the shortest path to the core objects, derivations, and proof skeletons.
They sit between courses and books:
- shorter than books
- denser than a full lecture sequence
- often better when you need to revisit one narrow topic while reading papers
2 How To Use Notes Well
Use notes when you want:
- a compressed second pass
- a fast return to notation and main derivations
- a topic-specific bridge while reading a paper
Do not expect notes to always be beginner-friendly. They are strongest when you already know what gap you are trying to close.
3 Good First-Pass Note Anchors
| Resource | Best for | Use it when |
|---|---|---|
| MIT 18.06 Lecture Notes | linear algebra objects, least squares, eigenvalues, matrix intuition | you want a compact companion to Linear Algebra after the first pass |
| STATS 202 Notes | regression, PCA, modern statistics-to-ML bridges | you want note-style refreshers instead of a full statistics textbook |
| MIT 6.241J Lecture Notes | state-space models, feedback, controllability, observers | you want a compact systems/control anchor after ODEs and Dynamical Systems |
4 Strong Second-Pass And Research Bridges
| Resource | Best for | Use it when |
|---|---|---|
| EE376A Lecture Notes | entropy, mutual information, coding, rate-distortion | you want the cleanest note-style anchor for Information Theory |
| MIT 6.441 Lecture Notes | information-theoretic proofs, source/channel coding structure | you want a second pass once the objects are familiar and the proofs matter more |
| STATS 305B Notes | regularization, lasso, high-dimensional estimation | you are moving from Statistics into High-Dimensional Statistics |
5 When Notes Beat Books
Notes are often the better choice when:
- the paper is using one theorem family and you only need that family
- you need to re-enter a subject quickly after time away
- you want notation and proof structure more than pedagogy
Books are better when you still need the big picture. Courses are better when you need pacing and worked examples.
