The course aims to introduce probabilistic graphical models for structured data, where data points are no longer independent with each other, such as sequential data and graph/network data. The course will cover modeling, inference, and learning of several classical probabilistic graphical models, including Hidden Markov Model, Markov Random Field, Conditional Random Field, and Factor Graph. Applications across different domains, such as text mining, medical domain, and social network analysis, will be discussed. The students are expected to read and present cutting edge research papers, as well as conduct a research oriented course project.

Part I: Lectures (5 weeks)

Part II: Paper Presentations (4-5 weeks, Feb. 12 - Mar. 14)

Part III: Course Project Presentation (Mar. 20, 8-11am)

- There is no official pre-requisite for this course.
- The students are expected to have knowledge in data structures, algorithms, basic linear algebra, and basic statistics. It is highly recommended that you have already had some background knowledge in data mining and machine learning. You will also need to be familiar with at least one programming language, and have programming experiences.

- Homework: 25%
- Paper presentation: 30%
- Research project: 40%
- Participation: 5%

*Note: all the deadlines are 11:59PM (midnight) of the due dates.

** Q & A**

This term we will be using Piazza for class discussion. The system is highly catered to getting you help fast and efficiently from classmates and myself. Rather than emailing questions to the teaching staff, I encourage you to post your questions on Piazza.

Tips: Answering other students' questions will increase your participation score.

"With its status as a world-class research institution, it is critical that the University uphold the highest standards of integrity both inside and outside the classroom. As a student and member of the UCLA community, you are expected to demonstrate integrity in all of your academic endeavors. Accordingly, when accusations of academic dishonesty occur, The Office of the Dean of Students is charged with investigating and adjudicating suspected violations. Academic dishonesty, includes, but is not limited to, cheating, fabrication, plagiarism, multiple submissions or facilitating academic misconduct."
