Very easy class, but I learned nothing. Lectures were pretty useless as they focused on highly theoretical concepts with very little practical applications. There was also very little room to learn during the homework assignments because they were a joke. This was disappointing as I anticipated this class to be one of the most important ones I would take. We didn't have a final exam and virtually had no homework. However, Shirong is very nice and I like him as a person. This was also his first time teaching a class at UCLA I believe, so I think with extra preparation on his part, he could teach this class in more applicable way in the future.
