Cloud computing helps organizations realize cost savings and efficiencies without spending capital resources up front, while modernizing and expanding their IT capabilities. Cloud-based infrastructure is rapidly scalable, secure, and accessible over the Internet—you pay only for what you use. So, enterprises worldwide, big and small, are moving toward cloud-computing solutions for meeting their computing needs, including the use of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). We have also seen a fundamental shift from shrinkwrapped software to Software as a Service (SaaS) in data centers across the globe. Moreover, providers such as Amazon, Google, and Microsoft have opened their datacenters to third parties by providing low-level services such as storage, computation, and bandwidth. This trend is creating the need for a new kind of enterprise architect, developer, QA, and operational professional—someone who understands and can effectively use cloud-computing technologies and solutions. In this course, we discuss critical cloud topics such as cloud service models (IaaS, PaaS, SaaS); virtualization and how it relates to cloud; elastic computing; cloud storage; cloud networking; cloud databases; cloud security; and architecting, developing, and deploying apps in the cloud. The format of this course will be a mix of lectures, and hands-on demos.

However, despite the many successes of machine learning algorithms, practitioners are increasingly realizing that complicated AI systems need algorithms from all three aspects. This approach falls under the ironic heading “Hybrid AI”. In this course, the foundational algorithms of AI are presented in an integrated fashion emphasizing Hybrid AI. The topics covered include state space search, local search, example based learning, model evaluation, adversarial search, constraint satisfaction problems, logic and reasoning, expert systems, rule based ML, Bayesian networks, planning, reinforcement learning, regression, logistic regression, and artificial neural networks (multi-layer perceptrons).

The focus of this course is on APIs for RESTful services and microservices, and interoperation across application components using APIs. The course also introduces the data exchange mechanism and common data formats, as well as security measures and solutions. At the end of this course, students will be able to apply a variety of techniques and will be able to: Apply best design principles, practices and patterns for creating APIs for RESTful services;Document API using YAML and RAML according to OpenAPI/Swagger specification; Create an API management discipline; Implement API security, control API versioning and life cycle stages; Build RESTful services with Spring Framework; Consume RESTful services using JSON and XML data formats; Integrate RESTful API with different data sources through hands-on coding projects; Build, package and deploy RESTful services on cloud-based platform; Conduct API testing using a variety of tools and techniques; Implement security mechanisms for controlling access to deployed services by service consumers using the Spring Security framework. Students will learn through guided lectures and real-world examples. Students will work on assignments and projects where they will apply newly learned techniques and best practices using the iterative approach of enhancing requested capabilities. Course Note(s): Students will be expected to already have a strong foundation in Java programming and to be comfortable with IDEs tools.
Prerequisite(s): EN.605.644 XML Design Paradigms or equivalent XML design and XML processing experience. EN.605.681 Principles of Enterprise Web Development or equivalent.
EN.605.795. Capstone Project in Computer Science. 3 Credits.
This course permits graduate students in computer science to work with other students and a faculty mentor to explore a topic in depth and apply principles and skills learned in the formal computer science courses to a real world problem. Students will work in self-organized groups of two to five students on a topic selected from a published list. Since students will have selected different courses to meet degree requirements, students should consider the combined strengths of the group in constituting their team. Each team will prepare a proposal, interim reports, a final report, and an oral presentation. The goal is to produce a publication quality paper and substantial software tool. This course has no formal content; each team should meet with their faculty mentor at least once a week and is responsible for developing their own timeline and working to complete it within one semester. The total time required for this course is comparable to the combined class and study time for a formal course. Course prerequisite(s): Seven computer science graduate courses including two courses numbered 605.7xx, all CS foundation courses, and meeting the track requirement; or admission to the post-master's certificate program. Students must also have permission of a faculty mentor, the student's academic advisor, and the program chair. Course note(s): Students may not receive graduate credit for both EN.605.795 and EN.605.802 Independent Study in Computer Science II. This course is only offered in the spring.
EN.605.801. Independent Study in Computer Science I. 3 Credits.
This course permits graduate students in computer science to work with a faculty mentor to explore a topic in depth or conduct research in selected areas. Requirements for completion include submission of a significant paper or project. Prerequisite(s): Seven computer science graduate courses including the foundation courses, three track-focused courses, and two courses numbered 605.7xx, or admission to the post-master’s certificate. Students must also have permission of a faculty mentor, the student’s academic advisor, and the program chair.
EN.605.802. Independent Study in Computer Science II. 3 Credits.
Students wishing to take a second independent study in computer science should sign up for this course. Prerequisite(s): EN.605.801 Independent Study in Computer Science I and permission of a faculty mentor, the student’s academic advisor, and the program chair. Course Note(s): A student may not receive credit for both EN.605.759 Independent Project in Bioinformatics and EN.605.802.
Prerequisite(s): EN.605.801 Independent Study in Computer Science I and permission of a faculty mentor, the student’s academic advisor, and the program chair.
