Course Description

This 3 credit, graduate-level course introduces fundamental elements of the emerging science of complex networks, with emphasis on social and information networks. Students will learn about mathematical and computational methods used to analyze networks, models used to understand and predict behavior of networked systems, and theories used to reason about network dynamics. Students will also be exposed to current research in the field, and they will be given an opportunity to explore a chosen topic through a semester project.

Topics to be covered include :

  • Network structure, modeling and algorithms
    • Graph theory essentials; Basic network properties; Random graphs; Spectral graph theory; Centrality; PageRank; Hubs and Authorities; Graph similarity; Community detection; Signed networks and structural balance; Graph embeddings and representation learning;
  • Network dynamics:
    • Cascading behaviors; Information diffusion; Epidemics models;  Influence maximization; The Small-world phenomenon; 
  • Temporal networks:
    • Models and algorithms for analysis of time-varying networks.

Learning Outcomes

At the conclusion of the course, students should be able to:

  • Explain basic metrics and measures used to characterize networks
  • Analyze a network using the various measures and a suitable network analysis software tool
  • Discuss the strengths and weaknesses of random graph models
  • Understand and apply key algorithms for link analysis (ranking), community identification, and network comparison
  • Understand and apply models and theories used to reason about cascading behaviors, information spread, and decentralized navigation in networks
  • Understand and explain the interdisciplinary nature of the area of network science
  • Critique research papers in the area
  • Apply knowledge gained in the course to carry out a project and write a scientific report

Audience

The course is suitable for graduate students in computer science, engineering, epidemiology, sociology, economics, mathematics, physics, and related fields.

Prerequisites

Students are expected to have basic knowledge of algorithms (equivalent to completing an undergraduate algorithms course such as CptS 350), some programming experience (e.g. in Python, R, or C), and familiarity with basic linear algebra (e.g. solution of linear systems and eigenvalue/vector computation) and basic probability and statistics.

Course Work

The course consists of lectures (twice a week, 75 min each) and involves in-class quizzes, a set of assignments, one exam, and a semester project.

  • Assignments (30%). There will be three assignments mostly spread through the first half of the semester. Assignments are to be completed and submitted individually.
  • Semester Project (40%). Working in teams of two or three, students will complete a semester project. A semester project could take one of several forms:  analysis of an interesting dataset using existing methods and software; comparison of existing methods and software tools in the context of a specific application; implementation of a new method; exploration of a chosen research topic.Each project will have required submissions at three different stages — the submissions are called Reaction Paper, Project Proposal and Final Report — and will culminate with an oral presentation in class.
    For the Reaction Paper part students will get to pick and read two closely related papers out of a list the instructor provides and write a short reaction paper summarizing and critiquing the two papers and identifying opportunities for further work. Project Proposal is a short document (2 or 3 pages long) that describes the proposed project and the tentative plan to carry it out. Ideally it is an outgrowth of the Reaction Paper component, but can also deviate from it. The outcome of the project will be a final report of about 8 to 12 pages long. Guidelines for writing the proposal and the final report will be provided at an appropriate time during the semester. A more complete project description detailing the various components will also be provided.
    The 40% weight of the semester project towards final grade is further broken down into its components as follows: Reaction Paper 5%, Project Proposal 5%, Presentation 5%, Final Report 25%.
  • Quizzes (10%). There will be a few occasional quizzes (in-class or homework) throughout the semester.
  • Mid-term Exam (15%). There will be one mid-term exam.
  • Class Participation (5%). Students are expected to actively participate in class discussions and in scribing notes for select lectures.

Expectations for Student Effort

For each hour of lecture equivalent, students should expect to have a minimum of two hours of work outside class.

Grading

Letter grades will be given according to the following ranges:

A (93–100%), A- (90–92.99%), B+ (87–89.99%), B (83–86.99%), B- (80–82.99%), C+ (77–79.99%), C (70–76.99%), C- (67–69.99%), D (60–66.99%), F (less than 60%).
