This course focuses on the fundamentals of computer algorithms, emphasizing methods useful in practice.  We look into the algorithm analysis as a way to understand behavior of computer programs as a function of its input size.  Using the big-O notation, we classify algorithms by their efficiency.  We look into basic algorithm strategies and approaches to problem solving.  Some of these approaches include the divide and conquer method, dynamic programming, and greedy programming paradigms.  Sorting and searching algorithms are discussed in detail as they form part of a solution to a large number of problems solved using computers.  We also provide an introduction to the graph theory and graph algorithms as they are also used in many computer-based applications today.  We conclude the course with a look into a special class of problems called the NP-complete problems.

This course will present advanced topics in Artificial Intelligence (AI).  We will begin by defining the term “software agent” and discussing how software agents differ from programs in general.  We will then take a look at those problems in the field of AI that tend to receive the most attention.  Different researchers approach these problems differently.  In this course, we will focus on how to build and search graph data structures needed to create software agents, an approach that you will find useful for solving many problems in AI.  We will also learn to “break down” larger problems into a number of more specific, manageable sub-problems. In the latter portion of this course, we will review the study of logic and conceptualize the differences between propositional logic, first-order logic, fuzzy logic, and default logic.  After learning about statistical tools commonly used in AI and about the basic symbol system used to represent knowledge, we will focus on artificial neural network and…

As data collection and information networks expand (and stories of security breaches and the misuse of personal information abound), data security and privacy issues are increasingly central parts of the information policy landscape. Legislators, regulators, businesses, and other institutions of all kinds are under increasing pressure to draft and implement effective laws, regulations, and security and privacy programs under rapidly changing technological, business, and legal conditions. A strong need is arising for individuals with the training and skills to work in this unsettled and evolving environment. This course examines security issues related to the safeguarding of sensitive personal and corporate information against inadvertent disclosure; policy and societal questions concerning the value of security and privacy regulations, the real-world effects of data breaches on individuals and businesses, and the balancing of interests among individuals, government, and enterprises; current and proposed laws and regulations that govern data security and privacy; private-sector regulatory efforts and self-help measures; emerging technologies that may affect security and privacy concerns; and issues related to the development of enterprise data security programs, policies, and procedures that take into account the requirements of all relevant constituencies, e.g., technical, business, and legal.
