DSCI 572: Supervised Learning II

An introduction to optimization for machine learning. Computation of derivatives. Deep learning.

2019 Instructor: Mike Gelbart

2019 Lecture Schedule

Course structure: this course will be delivered as a flipped classroom, which means you are expected to watch the lecture videos before class. While you're not expected to understand everything just from watching a video once, you're expected to come to class with a basic familiarity of what it's all about; we won't be starting again from scratch in class. During the lecture time itself, we will work on practical examples in Python. As a result of the extra 1-2 hours of time spent watching the videos per week, we will aim to make the labs shorter than in other courses.

Some context: these videos are from Mike's undergraduate machine learning course, CPSC 340, which contains a lot of the same material. They were filmed in January-April 2018. You can find the accompanying slides, and some supplementary readings, here. By the end of MDS we will cover roughly everything in CPSC 340, although often skipping over the implementation details. On the other hand, we cover machine learning topics that do not appear in CPSC 340, like time series data and natural language data. In MDS we also benefit greatly from the statistical perspective of "stat stream" courses.

Video timings: video links have start times embedded in them, which is where you are supposed to start watching from. End times are specified below if you're not supposed to watch the whole video. I recommend watching the videos at 1.25x speed.
