They will also know which kinds of analytics to apply to specific decision contexts.

Traditional test and evaluation approaches have focused on verifying that systems meet specified requirements or characterizing their effectiveness. These methods typically involve identifying relevant factors and quantifying uncertainty to determine how many samples are needed. However, AI-enabled systems—and other highly complex systems—vastly expand the possible state space and introduce nonlinear behaviors, making it impractical to gather enough real-world data to confidently ensure reliable performance in critical scenarios. This class addresses this challenge by broadening the types of evidence used to build confidence in system performance. Rather than relying solely on conventional testing, AI Assurance constructs structured arguments that link high-level claims about a system’s behavior to diverse forms of supporting evidence. This includes traditional test data as well as alternative sources, all tied together with clear reasoning and explicitly stated assumptions to justify trust in the system. In this seminar course, students will explore the emerging field of AI Assurance by reading and presenting academic papers, developing and presenting original research, and producing a publication-quality final paper as part of a capstone project.

This foundation course provides an overview of data analysis process, and introduces students to common techniques for data preprocessing, feature extraction, and the creation of statistical models.

This course provides a solid foundation of potential civil and criminal areas of liability, and certain areas in which compliance and risk management are critical. The overarching theme is detection and reduction of potential legal/cybersecurity risks. We start by exploring the legal and regulatory environment that influences and supports cyber-based activities and programs, focusing on multidisciplinary or integrated views of enterprise risk management. We will address key risk management issues from the legal and cybersecurity aspects and analyze legal/ cybersecurity issues in several of the critical infrastructure sectors, such as the financial services, healthcare and public health, and transportation systems sectors. We also review legal and regulatory compliance issues to address cybersecurity risk management for systems development, acquisition, and operation. This includes material impacting the manner in which the cyber community operates, for example, FITARA (Federal Information Technology Acquisition Reform Act) Enhancement Act of 2017. We then review the authoritative guidance provided by the National Institute of Standards and Technology (NIST) Cybersecurity Framework. The Framework is voluntary for the sixteen critical information sectors and mandatory for the federal government, hence the focus on NIST. Risk management threat detection and avoidance is analyzed from an integrated legal/cybersecurity perspective, including system objectives to avert legal liability and minimize enterprise and human loss. Examples address financial services, healthcare and public health, and transportation (mobile devices and autonomous vehicles) systems, and cyber-physical systems (CPS) or Internet of Things (IoT). The overall constitutional and statutory basis within which all cyber law and policy operates is identified and reviewed.

This course is to fortify and enrich the values-assessment and critical thinking skills of engineers as they grapple with the numerous ethical challenges in their professional and personal lives. To that end, the course will define and delineate some global, macro-level concepts and approaches to ethics; move on to review some ethical issues unique to engineers as they apply intelligent technologies such as artificial intelligence and machine learning to developing complex systems; and finally present some finite cases studies and concrete situations by which to apply these ethical principles. This class will stimulate students to help identify a critical thinking zeitgeist and framework by which to filter, absorb and resolve complex ethical problems and questions in both their professions and at the personal level. This class will be completely value-neutral and hence devoid of any one overarching governing ethical school of thought; thus, we are ecumenical in our approaches. Having said that, the IEEE ethically aligned design standards are noteworthy and very salutary to any exploration. This course will make use of a variety of current, recent historical and classical materials to illustrate major themes.

In many companies and government/military organizations, engineers are expected to be both innovators and creative managers. Organizations that desire to grow and to create value for their stakeholders depend on using all available capital resources: financial, human, intellectual and physical. They then seek to defend and control the value created. This course explores the engineer’s roles in innovation, invention, and value creation as a driving force in entrepreneurial technology ventures, established companies and governmental/military organizations, and the ways in which these organizations must plan to take full advantage of innovation as the only true competitive weapon in the battle for long-term success. Particular attention will be paid to collaboration and communication as key skills of the engineer/innovator/manager.
