The lab component of the course will cover mathematical concepts used in computational linguistics. The purpose of the lab is to familiarize you with not-so-basic probability theory, information theory, Bayesian inference, linear algebra, and descriptive and inferential statistics. These concepts are crucial in understanding computational linguistics and natural language processing algorithms covered in lecture. If you are shaky about these topics, you are recommended to attend the lab. If you are going to take CS134 next year (Statistical Natural Language Processing), the lab is highly recommended.
Lab instructor: Kenneth Lai
Place and Time: 2 p.m-3 p.m Friday weekly in Lown 201 depending on the progress of the class.
