课程简介
In this class, you will learn the basics of the PGM representation and how to construct them, using both human knowledge and machine learning techniques.
课程大纲
Topics covered include:
- The Bayesian network and Markov network representation, including extensions for reasoning over domains that change over time and over domains with a variable number of entities
- Reasoning and inference methods, including exact inference (variable elimination, clique trees) and approximate inference (belief propagation message passing, Markov chain Monte Carlo methods)
- Learning parameters and structure in PGMs
- Using a PGM for decision making under uncertainty.
There will be short weekly review quizzes and programming assignments (Octave/Matlab) focusing on case studies and applications of PGMs to real-world problems:
- Credit Scoring and Factors
- Modeling Genetic Inheritance and Disease
- Markov Networks and Optical Character Recognition (OCR)
- Inference: Belief Propagation
- Markov Chain Monte Carlo and Image Segmentation
- Decision Theory: Arrhythmogenic Right Ventricular Dysplasia
- Conditional Random Field Learning for OCR
- Structure Learning for Identifying Skeleton Structure
- Human Action Recognition with Kinect
To prepare for the class in advance, you may consider reading through the following sections of the textbook (discount code DKPGM12) by Daphne and Nir Friedman:
- Introduction and Overview. Chapters 1, 2.1.1 - 2.1.4, 4.2.1.
- Bayesian Network Fundamentals. Chapters 3.1 - 3.3.
- Markov Network Fundamentals. Chapters 4.1, 4.2.2, 4.3.1, 4.4, 4.6.1.
- Structured CPDs. Chapters 5.1 - 5.5.
- Template Models. Chapters 6.1 - 6.4.1.
These will be covered in the first two weeks of the online class.
The slides for the whole class can be found here.

这门课怎么样大家都知道了，我只能说非常刺激，放弃了大概1.7个作业，还好最后80分刚刚低空擦过。
个人觉得作业最难的部分在于怎么理解给出的接口API和数据结构设计，每次的pdf说明都不太清楚，第5、7周的作业太难主要也就是难在这两点上。所以光看懂讲课视频是不够的，实现细节还是得自己想。
大概有机会明年还得再来上一遍，欢迎各种抖M来enroll...

经典的概率图模型课程，Daphne Koller 老师所著的同名教材也是一本经典教材。看完视频并且完成所有习题作业和编程项目作业需要花费很多时间。如果时间紧张，也可以根据自己的需要学习一部分，教材里面给出了一张各个章节之间的依赖关系图，可以在掌握前面几章基础章节内容的前提下，对后面的章节有侧重的学习

我现在觉得最不可思议的事就是我居然第一轮就把这个课上完了。其实回过头想想，现在再上的话可能收获会更大些。

确实挺有难度的，属于graduate level的课程，一周花10+个小时几乎是必须的，对应的教材有1000+页。如果想弄懂概率图模型，这是一门极好的课~

收获最大，完成最艰苦的课程！PA经常卡壳，几乎每天2~3个小时做作业…
