Description
This course provides an introduction to modern natural language processing
using machine learning and deep learning approaches. Content includes
linguistics fundamentals (syntax, semantics, distributional properties of
language), machine learning models (classifiers, sequence taggers, Transformers, and large language models),
algorithms for decoding and inference, and contemporary methods for applying language models to solve
a range of problems. Students will get hands-on experience building systems to do tasks
including text classification, language modeling, and textual entailment.
Requirements
- CS 429
- Recommended: CS 331, familiarity with probability and linear algebra, programming experience in Python
- Helpful: Exposure to AI and machine learning (e.g., CS 342/343/363)
Course Details
The course lectures will be delivered in a traditional, in-person format. Recordings will be made available
via the LecturesOnline service for students to browse after class. All course materials will be posted
on this website. Note that additional pre-recorded video content overlapping with the concepts in this course
is available on the CS388 website.
The exam will be given in-person. Contact the instructor ASAP if this poses a problem for you.

Readings: Textbook and paper readings are assigned to complement the material discussed in lecture. You may find it useful
to do these readings before lecture as preparation or after lecture to review, but you are not expected to know everything discussed
in the textbook if it isn't covered in lecture.
Paper readings are intended to supplement the course material if you are interested in diving deeper on particular topics.
The chief text in this course is Eisenstein: Natural Language Processing,
available as a free PDF online.
(Another generally useful NLP book is Jurafsky and Martin: Speech and Language Processing (3rd ed. draft), with many draft chapters available for free online; however,
we will not be using it much for this course.)
