Course description.
This projectcentered graduate course will cover technical foundations of modern NLP.
Students are expected to start working on course projects immediately from the beginning of the course and throughout,
culminating in (1) inclass project presentations and (2) written reports that aspire to conference publication level.
The course will have two parts that happen in parallel.
The first part is standard lecturebased classes in which the instructor exposes students to fundamental concepts and applications in the field.
The second part is continual discussions and brainstorming about course projects and selfinitiated research efforts.
There is no required textbook: all materials are publicly available online resources.
Please use the
Canvas site to ask questions regarding lectures/homeworks/projects, to submit assignments, and to find announcements.
Goals.
 Achieving an understanding of the foundational concepts and tools used in modern NLP
 Obtaining an ability to critically read and accurately evaluate conference papers in NLP
 Finding new research projects that persist beyond this course
Audience and prerequisites.
No previous exposure to NLP is assumed. However, this is a fastpaced course designed for selfmotivated graduate or advanced undergraduate students with a solid technical background in probability and statistics, calculus, and linear algebra.
Technical requirements include:
 Probabilistic reasoning (e.g., What is the conditional probability of Y=y given X=x, assuming the knowledge of a joint distribution over X and Y?)
 Intimate and intuitive understanding of matrix and vector operations (e.g., What is the shape of a matrix product? How similar are two vectors?)
 Mathematical notions in optimization (e.g., What does it mean for a function to have zero derivative at a certain point?)
If you cannot complete
A1 comfortably, you may need to consult with the instructor about whether your background meets the prerequisites.
Significant programming experience in Python is necessary for programming assignments and course projects.
Grading.
 Project: 40% (written report 30%, presentation 10%)
 Exam (inclass and open book): 30%
 Assignments: 20%
 Participation: 10%
The assignment report must be written in LaTeX using the provided
assignment report template.
Similarly, the project report must be written in LaTeX using the provided
project report template and will be reviewed by the instructor like a conference submission.
Tentative plan.
