talk: Beyond Reactive Management of Network Intrusions, Noon 10/12 ITE456

Department of Information Systems Colloquium

Beyond Reactive Management of Network Intrusions

Professor Sushil Jajodia
Center for Secure Information Systems
George Mason University

12:00pm Wednesday, 12 October 2011, ITE456, UMBC

This talk will discuss issues and methods for survivability of systems under malicious attacks. To protect from such attacks, it is necessary to take steps to prevent attacks from succeeding. At the same time, it is important to recognize that not all attacks can be averted at the outset; attacks that are successful to some degree must be recognized as unavoidable and comprehensive support for identifying and responding to attacks is required.

In my talk, I will describe the recent research on attack graphs that represent known attack sequences attackers can use to penetrate computer networks. I will show how attack graphs can be used to compute actual sets of hardening measures that guarantee the safety of given critical resources. Attack graphs can also be used to correlate received alerts, hypothesize missing alerts, and predict future alerts, all at the same time. Thus, they offer a promising solution for administrators to monitor and predict the progress of an intrusion, and take appropriate countermeasures in a timely manner.

I will conclude my talk with a demo of the working system.

talk: Intelligent Agents in the OntoAgent Cognitive Architecture

EE Graduate Seminar

Intelligent Agents in the OntoAgent Cognitive Architecture

Professor Sergei Nirenburg
Director, Institute for Language and Information Technologies
Computer Science and Electrical Engineering

University of Maryland, Baltimore County

11:30am-12:45pm Friday 30 September 2011, ITE 231

OntoAgent is a constantly evolving cognitive architecture that facilitates development of and experimentation with artificial intelligent agents (ontoagents). Distinguishing characteristics of Ontoagents include the following.

  • They model human information processing capabilities by simulating conscious perception and action, which involves reasoning and decision-making;
  • They are intended to operate in a hybrid network of human and artificial agents; and
  • They incorporate: (a) an ontological world model and a memory (fact repository) of instances of ontological objects, events and properties; (b) OntoSem, a natural language processing module that supports two-way translation between texts (including dialog turns) and their semantic and discourse/pragmatic meanings; (c) a goal- and plan-oriented reasoning module; (d) a decision theory for choosing goals, plans and individual actions that relies on knowledge (beliefs) about self, other agents, the ontological world model, the current world state and memory of past world states and past actions; (e) a capability for verbal, mental and simulated physical action; (f) (optionally) a physiological model, making them what we call double agents with simulated bodies as well as simulated minds and providing an additional channel of perception; and (g) (optionally) personality traits, preferences and psychological states that influence their overtly perceived or subconscious preferences in decision-making.

OntoAgent has so far provided the basis for two proof-of-concept systems:

  • Maryland Virtual Patient (MVP) modeling a patient and a tutor to help training in medical diagnostics and treatment; and
  • CLinicians ADdvisor (CLAD) assisting clinicians by reducing their cognitive load.

This talk will give a brief introduction to OntoAgent functionalities implemented in MVP and CLAD.

Professor Nirenburg has worked in the areas of cognitive systems, artificial intelligence, and natural language processing (NLP) for over 30 years. His professional interests include developing computational models of human cognitive capabilities and implementing them in hybrid-engine models of societies of human and computer agents; computational studies of meaning in natural languages; and representation and management of knowledge about the world and about language. He is Member of the Intl Committee on Computational Linguistics (ICCL) and Honorary Editor of Machine Translation (served as Editor-in-Chief in 1987-96). He has been Program Committee Chair for: Machine Translation Summit III (Washington, DC, 1991), the Conference on Applied NLP sponsored by the Association for Computational Linguistics (Seattle, WA, 2000), and COLING 2004 in Geneva, Switzerland. He served as a director of two NATO-sponsored Advanced Studies Institutes on Language Engineering for Lesser-Studied Languages (Ankara, Turkey, 2000 and Batumi, Georgia, 2007).

Talk: Genetic information for chronic disease prediction

Genetic information for chronic disease prediction

Michael A. Grasso, MD, PhD
University of Maryland School of Medicine

1:00pm Friday 23 September 2011, 227 ITE

Type 2 diabetes and coronary artery disease are commonly occurring polygenic-multifactorial diseases, which are responsible for significant morbidity and mortality. The identification of people at risk for these conditions has historically been based on clinical factors alone. However, this resulted in prediction algorithms that are linked to symptomatic states, which have limited accuracy in asymptomatic individuals. Advances in genetics have raised the hope that genetic testing may aid in disease prediction, treatment, and prevention. Although intuitive, the addition of genetic information to increase the accuracy of disease prediction remains an unproven hypothesis. We present an overview of genetic issues involved in polygenic-multifactorial diseases, and summarize ongoing efforts use this information for disease prediction.

talk: Analysis of Brain Network Connectivity in fMRI Data using Spatial Dependence

EE Graduate Seminar

Analysis of Brain Network Connectivity
in fMRI Data using Spatial Dependence

Sai Ma
EE PhD Candidate, CSEE Dept, UMBC

11:30-12:45 Friday 9 September 2011, ITE 231

Due to low invasiveness and high spatial resolution, functional magnetic resonance imaging (fMRI) has become popular in neuroimaging field to determine where activity occurs in brain as a result of performing cognitive tasks or merely being at rest.  One of the most active areas in current fMRI research involves exploring functional connectivity, i.e., statistical interactions, among distributed neural units. Understanding connectivity elucidates how functional systems process information in brain. More interestingly, disorganized connectivity has shown to be related to various kinds of mental disorder.

Data-driven methods, especially independent component analysis (ICA), have been successfully applied to fMRI data analysis and provided an opportunity to study brain functional connectivity on a network, hence multivariate scale. However, independence is a strong assumption which is not necessarily nor typically satisfied in real applications. For this reason, dependent component analysis (DCA) has emerged to generalize ICA by grouping components into independent subsets while within subset dependence is allowed.

Based on ICA and motivated by DCA, we aim to develop effective and efficient analysis schemes to extract, characterize, and quantify network connectivity pattern in fMRI data. We define functional network connectivity as spatial dependence among ICA-derived components, instead of second-order temporal correlation between time courses, to capture high-order statistics. According to this definition, we present our work on the study of network connectivity by several data-driven methods, including ICA, DCA, hierarchical clustering, hypothesis testing, and graph theoretical analysis.
