EECS 444/544: Analysis of Societal Networks
Instructor: Professor Vijay Subramanian
Networks are everywhere. We encounter a variety of networks of different sizes and forms on a daily basis: societal networks such as the network of retweets of a certain hashtag on Twitter or the friends network on Facebook; technological networks such as the Internet with the telecommunication network of computers, the links between webpages, the groupings of users generated by recommendation systems for predictions or the network of users on BitTorrent downloading a specific file; and economic networks such as trade networks or supply-chain networks. Some of these networks emerge naturally such as many societal networks, while others are planned such as the public transportation or road network. We depend on the efficient functioning of these networks to transact many of our activities. This course serves as an introduction to the broad class of networks described above: how these networks are connected, how they form, how processes and transactions take place on them, and how Facebook Friends Network Food Contamination Spread Network between Countries Sample Network of Brain Regions London Underground Network they are being transformed and interconnected in the modern world. Students will learn how to develop and apply mathematical models and tools from graph theory, linear algebra, probability and game theory in order to analyze network processes such as how opinions and fads spread on networks, how sponsored advertisements are developed, how web content is displayed, how recommendation systems work, etc.

A .pdf copy of the textbook is freely available online on the author Jon Kleinberg’s website.
We may also use material from the following books:
- Networks: An Introduction, M. E. J. Newman, Oxford University Press, 2010
- Social and Economic Networks, Matthew O. Jackson, Princeton University Press, 2010
Additionally, we may use research articles and papers as further reading material. These will be posted on the course website and/or distributed in class.

Most necessary mathematical tools will be developed as a part of the course. However, students are assumed to have some mathematical sophistication (some familiarity with proofs, basic understanding of probability, some exposure to linear algebra and graph theory, etc.). EECS 444: EECS 301, MATH 425 or STATS 425, C or better for prerequisites EECS 544: EECS 301, MATH 425 or STATS 425, or Graduate Standing and C or better for prerequisites
EECS 203 and EECS 453/551 would be useful but not required.
