Syllabus Topics

This course will be an advanced topic seminar class on natural language processing, focusing on the recent advances via diverse learning paradigms such as:

This will be a research-oriented grad-level seminar course, where we will read lots of interesting research papers, brainstorm about ideas on latest research topics, and code and write up fun and novel projects!
Please email me or drop by my office if you have any questions!


Prerequisites

Since this is an advanced topics NLP class, the student is expected to have equivalent experience to Dr. Bansal's fall 2016 or fall 2017 regular NLP class.


Grading (tentative)

Grading will consist of:

Details in first class intro lecture slides. There will not be any exams. All submissions should be emailed to: nlpcomp790unc@gmail.com


Lateness Policy

Students are allowed 3 free late days for assignments over the semester. After that, late assignments will be accepted with a 20% reduction in value per day late.


Collaboration Policy

Paper summaries have to be written and submitted individually. Paper presentations have to be done individually. Projects can be individual (e.g., if it relates to your current research) or in pairs (but with proportional work, and with clearly outlined contributions from each team member).
