Ramat-Gan, 52900 Israel

12:00-1:00pm Friday, 4 August 2017, ITE ITE 217B, UMBC

Automated agents that interact proficiently with people can be useful in supporting, training or replacing people in complex tasks. The inclusion of people presents novel problems for the design of automated agents strategies. People do not necessarily adhere to the optimal, monolithic strategies that can be derived analytically. Their behavior is affected by a multitude of social and psychological factors. In this talk I will show how combining machine learning techniques for human modeling, human behavioral models, formal decision-making and game theory approaches enables agents to interact well with people. Applications include intelligent agents that help drivers reduce energy consumption, agents that support rehabilitation, employer-employee negotiation and agents that support a human operator in managing a team of low-cost mobile robots in search and rescue task

1:00-2:00pm, Friday, 5 May 2017, ITE 231

The White House announced the Smart Cities Initiative with an $160 million investment to address emerging challenges in this inevitable urbanization. Under the scope of this initiative, my work addresses emerging problems in the smart energy systems in connected communities with a data-driven approach, including sensing hardware design, streaming data collection to data analytics and privacy, system modeling and control, application design and deployments. In this talk, I will focus on an example of data driven solutions for data and energy management in smart grids. I will first show how to collect the energy data from large-scale deployed low-cost smart meters and minimize the communication and storage overhead. Then I will show how we can conduct energy data analytics with the collected energy data and utilize data analytics results for real-time energy management in a microgrid to minimize the operational cost. Finally, I will present the real-world impact of my research and some future work about CPS in smart cities.

talk: Big Microbiome Data, 10am Tue May 2, UMBC

Information Systems Eminent Scholar Talk

Big Microbiome Data

Xiaohua Hu, Drexel University

10:00am Tuesday, 2 May 2017, ITE 459, UMBC

We know little about the microbial world. Microbiome sequencing (i.e., metagenome, 16s rRNA) extracts DNA directly from a microbial environment without culturing any species. Recently, huge amount of data are generated from many micorbiome projects such as Human Microbiome Project (HMP), Metagenomics of the Human Intestinal Tract (MetaHIT), et al. Analyzing these data will help us to better understand the function and structure of microbial community of human body, earth and other environmental eco-systems. However, the huge data volume, the complexity of microbial community and the intricate data properties have created a lot of opportunities and challenges for data analysis and mining. For example, it is estimate that in the microbial eco- system of human gut, there are about 1000 kinds of bacteria with ten billion bacteria and more than four million genes in more than 6000 orthologous gene family. The challenges are due to the complex properties of microbiome: large-scale, complicated, diversity, correlation, composition, hierarchy, incompleteness etc.

Current microbiomes data analysis methods seldom consider these data properties and often make some assumptions such as linear, Euclidean space, metric-space, continue data type, which conflict with the true data properties. For example, some similarities are non-metric because the prevalent existence of some species; and the interactions among species and environment are complex in high order. Thus it is urgent to develop novel computational methods to overcome these assumptions and consider the microbiome data properties in the analysis procedure.  In this talk, we will discuss some computational methods to analyze and visualize microbiome big data. Our studies are focusing on 1) novel machine learning and computational technologies for dimension reduction and visualization of microbiome data based on non-Euclidean spaces (manifold learning) to discover nonlinear intrinsic features and patterns in these data to overcome the linear assumptions, 2) novel statistical methods for variable selection in microbiome data by integrating group information among variables.

talk: Practical Introduction to Penetration Testing , 12pm 4/28, ITE227, UMBC

The UMBC Cyber Defense Lab presents

A Practical Introduction to Penetration Testing

Dr. Arno Wacker
University of Kassel, Germany
and UMBC 2017

12:00noon Friday, 28 April 2017, ITE 227, UMBC

While many students learn the theoretical concepts of cybersecurity and cryptology at universities, their exposure to real life systems and the application of learned theoretical foundations in the real world is usually limited. Additionally, most students and sometimes even students of cybersecurity often deal with cybersecurity threats on a very abstract level, thereby being unaware that these threats are not abstract but real for everyone, including for themselves.

Therefore, this talk intends to raise the awareness about real cybersecurity threats for everyone by demonstrating live the process of penetration testing a system. I will show live how an attacker can gain control over a victim’s PC in a matter of seconds, and how this attack can be prevented. To do so, several techniques and tools will be used, including breaking a WPA-protected wireless network, defeating SSL/TLS encryption, and obtaining a reverse shell with system rights on the victim’s computer.

By experiencing these attacks in a simulated penetration test, we can gain a deeper understanding of the theoretical foundations and their implications for real-life scenarios. With this knowledge, the attack vectors can be mitigated to a bare minimum. In many cases, the cybersecurity-aware usage of IT systems is already countering many real threats.

Prof. Dr. Arno Wacker is an assistant professor with the University of Kassel in Germany and the head of the research group Applied Information Security (AIS). Currently, he is a visiting assistant professor at UMBC teaching the network security class. He is also the lead of the open source project CrypTool 2  and a member of the steering group of MysteryTwister C3 .

talk: Human-Like Strategies for Language-Endowed Intelligent Agents, 11am Fri 4/48, UMBC

The UMBC Center for Hybrid Multicore Productivity Research (CHMPR)
is pleased to present as part of our distinguished lecture series

Human-Like Strategies for Language-Endowed Intelligent Agents

Dr. Sergei Nirenburg
Professor of Cognitive Science
Rensselaer Polytechnic Institute

11:00am Friday, 28 April 2017, ITE 325b


Artificial intelligent agents functioning in human-agent teams must correctly interpret perceptual input and make appropriate decisions about their actions. These are arguably the two central problems in computational cognitive modeling. The RPI LEIA Lab builds language-endowed intelligent agents that extract meaning of text and dialog and use the results together with input from other perception modes, a long-term belief repository, rich models of the world and of other agents, and a model of the interaction situation to make decisions about actions. Specific phenomena we currently concentrate on include incrementality, treatment of unexpected input and non-literal language (e.g., metaphor), analysis of agent biases and “mindreading,” and deliberate concept learning. All these studies are characterized by our belief in the ultimate utility of building causal models of agent capabilities that are inspired by human strategies in language processing and decision-making that go beyond analogical reasoning. In this talk I will give an overview of our recent work in the above areas.

Sergei Nirenburg is Professor of Cognitive Science and Computer Science at the Rensselaer Polytechnic Institute. He also serves as Head of the Department of Cognitive Science. He has worked in the areas of cognitive science, artificial intelligence and natural language processing for over 35 years, leading R&D teams of up to 80. Dr. Nirenburg’s professional interests include developing computational models of human cognitive capabilities and implementing them in computer models of societies of human and computer agents, continuing development of the theory of ontological semantics, and the acquisition and management of knowledge about the world and about language. Academic R&D teams under Dr. Nirenburg’s leadership have implemented a variety of proof-of-concept and prototype application systems for cognitive modeling, intelligent tutoring and a variety of NLP tasks (machine translation, question answering, text summarization, information extraction, computational field linguistics, knowledge elicitation and learning). Dr. Nirenburg has written two and edited five books and published over 200 scholarly articles in journals and peer-reviewed conference proceedings.

talk: Resynchronization of circadian neurons, 1pm Fri 4/21

UMBC CSEE Seminar Series

Resynchronization of circadian neurons and the east-west asymmetry of jet-lag recovery

Zhixin Lu
University of Maryland, College Park

1-2pm Friday, 21 April 2017, ITE 231

Cells in the brain’s Suprachiasmatic Nucleus (SCN) are known to regulate circadian rhythms in mammals. We model synchronization of SCN cells using the forced Kuramoto model, which consists of a large population of coupled phase oscillators (modeling individual SCN cells) with heterogeneous intrinsic frequencies and external periodic forcing. Here, the periodic forcing models diurnally varying external inputs such as sunrise, sunset, and alarm clocks. We reduce the dimensionality of the system using the ansatz of Ott and Antonsen and then study the effect of a sudden change of clock phase to simulate cross-time-zone travel. We estimate model parameters from previous biological experiments. By examining the phase space dynamics of the model, we study the mechanism leading to the difference typically experienced in the severity of jet-lag resulting from eastward and westward travel.

Zhixin Lu, PhD Candidate, joined the Nonlinear Dynamics and Chaos Group in the University of Maryland, College Park in 2011, as a Graduate Research Assistant in Dr. Edward Ott’s group. He acquired expertise in nonlinear dynamics and complex systems. Together with the colleagues from UMD, he used methods from nonlinear dynamics theory to investigate the synchronization of circadian neurons, the statistical properties of critical avalanching firing in integrate-and-fire neuron models, as well as dynamical behavior of artificial recurrent neuronal networks. His main research interests are the applications of nonlinear dynamics and the theory of complex networks to biological and artificial neural networks.

talk: Dynamic Causal Modelling of Neuroimaging Time Series and Current Applications in Psychiatric Research

UMBC CSEE Seminar Series

Dynamic Causal Modelling of Neuroimaging (hemodynamic) Time Series and Current Applications in Psychiatric Research

Eugenia Radulescu
The Lieber Institute for Brain Development

1-2pm Friday, 14 April 2017, ITE 231

Abnormal neural processing due to interregional dysconnectivity at brain systems level is widely accepted as a generic mechanism in the etiopathogeny of major psychiatric disorders (i.e., schizophrenia and autism). Dynamic Causal Modeling (DCM) is a modern framework for creating, estimating and comparing generative models of hemodynamic time series, useful for investigating the effective connectivity of neuronal populations. This presentation will discuss the role of DCM in mapping the “ineffective” connectivity between brain regions in mental disorders and it will be structured in three parts: a. An introduction to the theoretical background of DCM applied to task-dependent hemodynamic response during functional MRI; b. Examples of clinical applications of DCM in schizophrenia and autism; c. Challenges and limitations of DCM in psychiatric research, followed by a general question: how can collaborate psychiatrists, computer scientists and engineers in improving and better adapting mathematical models for understanding the biological disturbances in psychiatric conditions.

Eugenia Radulescu, MD, PhD joined the Lieber Institute in 2013, as a Research Fellow in Dr. Weinberger’s group. She earned her MD and PhD at the University of Medicine and Pharmacy “C. Davila” Bucharest, Romania and practiced as a psychiatrist for thirteen years before switching to a career in psychiatric research. In 2003-2009 she was a post-doctoral fellow in Dr. Weinberger’s lab, Clinical Brain Disorders Branch, NIMH/ NIH. There Eugenia acquired expertise in neuroimaging methods- structural and functional MRI. Together with the colleagues from the Neuroimaging Core, she used these methods to investigate the effects of schizophrenia risk genetic variants on well characterized imaging intermediate phenotypes. In 2010-2014 Eugenia was a visiting fellow at Brighton and Sussex Medical School and Sackler Center for Consciousness Science in United Kingdom, where she continued to use MRI for studying brain structural and functional abnormalities associated with neurodevelopmental disorders (i.e. schizophrenia and autism). In the Division of Clinical Sciences at Lieber Institute, she pursues her long standing interest in applying complex fMRI analytical methods to test genetic epistasis effects on brain networks relevant as novel drug targets in neuro-developmental disorders.

talk: Stepping Away From the Edge of Illness, 4:30p Thr 4/6

CHMPR Distinguished Lecturer Series

Stepping Away From the Edge of Illness

Dr. Ancha Baranova, George Mason University

4:30-5:30pm Thursday, 6 April 2017, UC 310, UMBC
3:30-4:30pm Reception, UC 310

The human body may be afflicted by a multitude of chronic diseases. In principle, any chronic ailment develops along with one or more of the four fundamental pathophysiological processes, namely Insulin Resistance, Systemic Inflammation, Metabolic Deficiency and Tissue/Organ Involution and Degeneration. All of these four fundamental processes are known harbingers of the aging process. Borders between health and disease are blurry, and typical diagnostic cut-offs are arbitrary and in the recent past were subjects for revision. Therefore, neither physicians nor patients should wait until clear signs of crossing the border between health and sickness manifest themselves. To the contrary, they must constantly at all times consciously apply their efforts to ensure the maintenance of proper body homeostasis. By doing so, they can best resist the metabolic derangement which defines an “aged” state. Optimally, for humans to remain healthy throughout inevitable process of aging, biochemical parameters must be monitored longitudinally and balanced with available means. For relatively healthy individuals, these means should be centered on non-pharmacological, predominantly nutritional and nutraceutical approaches. Accordingly, it is reasonably foreseeable that a novel “Health Integrator” profession is anticipated to emerge in order to support the growing need for life-long health maintenance.

Dr. Ancha Baranova is an Associate Professor in School of Systems Biology, George Mason University, Fairfax VA. Dr. Baranova runs both experimental and computational research programs in highly interdisciplinary and collaborative field of Personalized Medicine. She is an expert in systems biology driven analysis of human metabolism, with an emphasis on diseases associated with the process of ageing. She is an author of more than 150 research papers, reviews and opinion pieces in the field of human systems biology.

talk: Quantum plane and plucking polynomial of rooted trees, 1pm 4/7

UMBC CSEE Seminar Series

Quantum plane and plucking polynomial of rooted trees

Józef H. Przytycki
George Washington University

1:00-2:00pm, Friday, 7 April 2017, ITE 231

We describe here a new invariant of rooted trees and following up state sum invariant of pointed graphs. We argue that the invariant is interesting on it own, and that it has connections to knot theory and homological algebra. Another reason that we propose this invariant is that we deal here with an elementary, interesting new mathematics and after the talk everybody can take part in developing the topic, inventing new results and connections to other disciplines of mathematics (and likely statistical mechanics and combinatorial biology). The staring point of the talk is the well known formula for $(x+y)^n$ in the quantum plane ($yx=qxy$).

Józef Henryk Przytycki is a mathematician specializing in the fields of knot theory and topology.  A native of Poland, Przytycki received a Master of Science degree in mathematics from Warsaw University in 1977 and, after emigrating to the United States, a Ph.D. in mathematics from Columbia University, where his advisor was Joan Birman. He is currently a professor of mathematics at George Washington University in Washington, DC. He has supervised nine Ph.D. students and has authored and co-authored many mathematical publications, including more than 100 research papers, 10 conference proceedings and 2 books.

talk: Making in the Classroom: Rationale, Challenge & Imperative, 3pm April 6, UMBC


Making in the Classroom: the Rationale, the Challenge and the Imperative

Professor Francis Quek
Department of Visualization, Texas A&M University

3:00-4:00pm Thursday, 6 April 2017, ITE 217, UMBC

Computing is increasingly focused in interaction with the physical world rather than just in the abstract virtual world of screens and pixels. Physical computing combines the design of physical electronics with computation to bring about possibilities that simply interacting with pixels behind glass cannot. One manifestation of physical computing in our culture is seen in the Maker movement. Technologies such as 3D printing and open source electronics and accessible computing have combined to give rise to a Maker movement that promises to broaden participation in technology-based innovation and production. The potential of Making to enhance learning, especially in areas of Science, Technology, Engineering and Mathematics (STEM) has led to calls to bring Making into education. However, the characteristics of innovation, discovery, and student-directed learning for which Making is prized is not easily incorporated into public school learning. Making-based learning are thus often provided in clubs, community Makerspaces, and workshops. This poses a severe issue of equity as youth participants are implicitly self-selected through parents who have the knowledge and means to enroll their children at such venues. Taking a human-centered perspective, we present a project where Making is integrated with the formal curriculum of a public elementary school that serves predominantly underrepresented populations. We will examine the rationale for employing Making-based classroom learning and review our strategy for curriculum alignment. We will see how our ‘double scaffolding’ approach supports both learning of STEM curricula and knowledge and skills associated with computing and Making. Beside learning STEM material, our approach seeks to support the development of STEM self-efficacy and self-identities in children who may not otherwise see these possibilities in themselves. We present results of our year-long study that show the promise of our approach.

Professor Francis Quek is a Professor of the Department of Visualization (and by courtesy, Professor of Computer Science and Engineering and Professor of Psychology) at Texas A&M University.
