Title: Securing Cyber-Physical and IoT Systems in Smart Living Environments
Abstract: Our daily lives are increasingly dependent on a variety of smart cyber-physical infrastructures, such as smart cities and buildings, smart energy grid, smart transportation, smart healthcare, etc. Alongside, smartphones and sensor-based IoTs are empowering humans with fine-grained information and opinion collection through crowdsensing about events of interest, resulting in actionable inferences and decisions. This synergy has led to the cyber-physical-social (CPS) convergence with human in the loop, the goal of which is to improve the “quality” of life. However, CPS and IoT systems are extremely vulnerable to failures, attacks and security threats. This talk will highlight unique research challenges in securing such systems, followed by novel defense mechanisms. Our proposed frameworks and solutions are based on a rich set of theoretical and practical design principles, such as secure data fusion, uncertainty reasoning, information theory, prospect theory, reputation scoring, and belief and trust models. Two case studies will be considered: (1) Security forensics and lightweight statistical anomaly detection in the smart grid CPS to defend against organized and persistent adversaries that can launch data falsiﬁcation attacks on the smart meters using stealthy strategies. The novelty of our approach lies in a newly defined information-theoretic metric that helps quantify robustness and security, thus minimizing the attacker’s impact on the customers and utilities with low false alarm rates; (2) Secure and trustworthy decision making in mobile crowd sensing to detect false (or spam) contributions due to selﬁsh and malicious behavior of users. Based on the cumulative prospect theory and reputation/trust model, our approach prevents revenue loss owing to undue incentives and improves the operational reliability and decision accuracy. The talk will be concluded with directions for future research.

Title: Teaching, Learning and Mentoring Computational Thinking Online in Bangladesh for Younger Students and In-Service Professionals
Abstract: With the future likely to see even more pervasive computation, computational thinking (problem-solving skills incorporating computing knowledge) is now being recognized as a fundamental skill needed by all students. Computational thinking is conceptualizing as opposed to programming, promotes natural human thinking style than algorithmic reasoning, complements and combines mathematical and engineering thinking, and it emphasizes ideas, not artifacts. But teaching and mentoring for computational thinking is not an easy task, let alone doing
so online and fully automatically.
In the context of Bangladesh, we juxtapose the computer science for all programs in USA and Bangladesh and discuss how new smart learning tools such as MindReader, vTutor, CodeMapper and OpenSchool are reshaping mass teaching of computational thinking online. We also discuss how such systems potentially have a significant impact on self-learning and free-choice learning, and promote effective learning and discourage and guard against plagiarism by leveraging authentic assessment. We leave the audience with some food for thought on the direction Bangladesh might consider taking.

Title: Automated Program Repair
Abstract: Software systems, are prone to vulnerabilities which can be exploited. One of the key difficulties in building trustworthy software systems – is the lack of specifications, or intended behavior, or a description of how the software system is supposed to behave. In our work, we have developed semantic analysis techniques to extract or discover specifications from an erroneous or vulnerable program. Such a specification discovery process helps in automatically generating repairs, thereby moving closer to the goal of self-healing software systems. As more and more of our daily functionalities become software controlled, and with the impending arrival of technology like personalized drones, the need for self-healing software has never been greater. There exist exciting possibilities for combining semantics based repair approaches with search-based repair, and this is under investigation in our research team. We envision that automated repair capabilities should be integrated into programming environments in the future. We will also discuss the possibility of using automated repair for grading and teaching of introductory programming to various learner groups, and this is of particular interest to countries of the world which have a large young population.

Title: Upskilling the future workforce through Affective training
Abstract: Fifty percent of the current activities in the US are technically automatable by adapting existing technologies. For example, each industrial robot in manufacturing replaces six workers. As a result, most individuals favor limits on replacing jobs through automation. While demand for physical and manual labor is declining, there is a huge demand for a workforce with social-emotional and technological skills.
The workforce of the future will have to be creative and innovative, rather than merely good at performing specific tasks. But the problem is that any individuals lack these skills, particularly if they suffer from cognitive disabilities or difficulties. Many argue that those skills are either innate or require extensive practice with human experts.
In our ongoing work, we show an early promise of using technology to recognize the subtle nuances of soft behavioral skills and provide meaningful feedback to the participants whenever they want, wherever they want. We demonstrate that, artificial intelligence, when designed appropriately, can successfully aid individuals in tasks such as job interviews, public speaking, negotiations, working as part of a team, helping patients with Parkinson’s to monitor their symptoms, end-of-life communication between doctors and patients, and even routine social interactions for people with autism. In this talk, I will share our ideas on using AI to improve human ability with two guiding principles in mind: 1) augment human beings rather than replace them; 2) be mindful of the potential misuse by recommending policy and social implications.

Title: Big Data to Machine Intelligence
Abstract: The future of machine intelligence is continuously being paved by novel advancements in computing technology and rapid progress in data analytics. Analytical models help explore knowledge and empower decision support but the knowledge must be stored and linked efficiently to connect the relevant pieces for optimum decision support. Cognitive computing enhances human level recognition and linking of knowledge to improve service quality, but fundamentally, everything is made possible by data ingestion and processing systems. This talk will discuss the enablers of machine intelligence and present some of our work in this regard specifically on streaming multimodal data ingestion and processing, knowledge management system, machine learning, cognitive computing, and decision support.
