Class Summary:

In this course we will examine some of the core tasks in natural language processing, starting with simple word-based models for text classification and building up to rich, structured models for syntactic parsing and machine translation. In each case we will first cover classic approaches, then review recent research progress and finally discuss with the help of guest lecturers (from Google) how to design efficient systems for practical user applications. There will be a focus on corpus-driven methods that make use of supervised and unsupervised machine learning methods and algorithms. We will explore statistical approaches based on graphical models and deep learning.

Your grade will be composed of 4 components:

Scribe sheet signup. Scribe notes are due 2 weeks after the lecture, except for the 12/5 scribe notes which are due in one week. Please pick a lecture to scribe for. Here is a template to use for the notes.

Late policy: You get 7 late days to use at your discretion (no more than 5 per assignment). After that you lose 10% per day. Please note that late days cannot be used for the final project.
