Talk: Dr.Rosenbloom on Three Related Takes on Investigating Human-Like Intelligence
On October 11th, 2019, Dr. Paul Roosenbloom, distinguished speaker from Lockheed Martin delivered a talk on ” Three Related takes on investigating Human-like intelligence”. This talk explored a trio of related takes on how to investigate the nature of human-like intelligence. The first concerns cognitive architectures – implemented models of the fixed structure and processes that yield natural and artificial minds – with a drill down to Sigma, an attempt at a deep synthesis across what has been learned over the past four decades on (what started as) high-level symbolic cognitive architectures versus the low-level graphical/network technologies of probabilistic graphical models (such as Bayesian networks) and neural networks. The second concerns a more abstract attempt at specifying a Common Model of Cognition that yields an evolving community consensus over what must be part of any cognitive architecture for human-like intelligence. The final take concerns an even more abstract (and speculative) attempt at understanding more deeply the space of approaches to intelligence – framed as maps resulting from cross products among core cognitive dichotomies – along with how such maps may help to understand and structure the capabilities required for (human-like) intelligence.
This event was attended by more than 100 members spilling out into the hallway.

TALK: Computer Aided Assessment of Computed Tomography Screenings
UMBC ACM Chapter Talk
Computer Aided Assessment of Pulmonary Nodule Malignancy in from Low Dose Computed Tomography Screenings
Professor David Chapman, CSEE, UMBC
11:30–12:30, Friday 11 October 2019, ITE 346, UMBC
We propose to develop a novel quantitative algorithm to estimate the probability of malignancy of pulmonary nodules from a time series of successive LDCT screenings in patients with a high risk of developing lung cancer. Lung cancer kills approximately 200,000 Americans annually and is responsible for 25% of all cancer-related deaths. Imaging with Low Dose Computed Tomography (LDCT) has been proven to reduce Non-Small Cell Lung Cancer (NSCLC) mortality by 20% and has become standard guidelines (NLST 2011a,b). These new clinical guidelines have led to hospitals, including Mercy Medical Center in Baltimore, to collect an abundance of LDCT images of high risk individuals since 2014. These LDCT images along with additional CT/biopsy and PET/CT images collected by Mercy hospital in Baltimore have now been organized into an IRB exempt clinical research dataset to use anonymous radiology imagery for the purpose of training and evaluation of improved Computer Aided Diagnosis (CAD) algorithms. Imaging biomarkers including cross-sectional diameter, calcification patterns, irregular margins, wall thickness all of which are known to have discriminating power to differentiate benign and malignant pulmonary nodules. Furthermore, temporal changes in the size and biomarker characteristics of pulmonary nodules over multiple images are also highly informative and yield greater ability to differentiate malignancy. The proposed CAD algorithm will be capable of detecting and quantifying temporal changes of imaging biomakers in order to estimate malignancy probability. The algorithm will make use of convolutional neural networks for feature extraction as well as recurrent neural networks to analyze the temporal changes in extracted features. The Mercy hospital dataset contains approximately 30,000 chest CT images. Training of the algorithm will incorporate semi-supervised learning using chest CT images from Mercy as well as the public portion of the NLST dataset. A fraction of the Mercy images will be designated for evaluation of the sensitivity and specificity of the proposed algorithm for determining nodule malignancy. Pulmonary nodules remain a challenging area for clinical management decision-making, and improved analysis of malignancy including temporal changes of imaging biomarkers have the potential to reduce patient morbidity and mortality through earlier and more accurate diagnosis.
Talk: Localization of Brain Activations Based on EEG Recordings and Sparse Signal Recovery Theory
Electrical and Computer Engineering Rutgers University
1:00-2:00pm Friday, 1 November 2019
Room 104, ITE Building, UMBC
Sparse signal recovery is often formulated as an l1-norm minimization problem. However, unless certain conditions are satisfied, there is no guarantee that the least l1-norm solution will also be a sparsest solution. In this talk, we show that by appropriately weighting the sensing matrix, we can formulate an l1-norm minimization problem whose solution is guaranteed to be one of the sparsest solutions. The weights can be obtained based on a low resolution estimate of the sparse signal, obtained for example via a method that does not encourage sparsity.
The proposed weighting approach is a good candidate for Electroencephalography (EEG) sparse source localization, where measurements of sensors, placed on a subject’s head are used to localize activations inside the brain. In many cases, the locations of these activations are related to the subject’s reactions or intensions, and estimating them via a non-invasive and inexpensive modality like EEG can find applications in several domains, including cognitive and clinical neuroscience as well as brain-computer interfaces (BCIs). In response to simple tasks, the brain activations are sparse, and thus, their localization based on the EEG recordings can be formulated as a sparse signal recovery problem. In this case, the corresponding basis matrix, referred to as lead field matrix, has high mutual coherence, which means that the least l1-norm solution will not necessarily lead to the brain sources. In spite of the high coherence of the lead field matrix, the proposed weighting approach can still estimate the sources inside the brain. In this talk, this is demonstrated by localizing active sources in the brain corresponding to an auditory task from EEG recordings of human subjects.

Talk: Impacting healthcare through collaborative technology innovations, 1:30pm Mon 7 Oct
Impacting healthcare through collaborative technology innovations
India’s healthcare scenario presents a set of unique challenges to ensure effective delivery of care to the large population suffering from various communicable and non communicable diseases. The medical devices market in India is largely catered by imports, most of which were not designed to handle the constraints and requirements of country’s care delivery system and market. While this presents a significant challenge to established players, it is an exciting opportunity for innovators and entrepreneurs to create and scale indigenous technology solutions tailored to local needs. However, development of affordable technology solutions which create large impact, and can achieve scale in India requires a deep understanding of the care delivery system and strong partnerships with various stakeholders of the ecosystem.
Healthcare Technology Innovation Centre of IIT Madras focuses on developing and commercializing affordable healthcare technologies through its team of over 200 engineers, doctors, researchers, students and entrepreneurs working with more than 30 medical institutions, industries, government agencies. The talk will highlight some of its technology successes and the use of AI and machine learning in tackling the healthcare challenges. The potential of these technologies beyond Indian market will be discussed.

talk: Analysis of the Secure Remote Password (SRP) Protocol Using CPSA
The UMBC Cyber Defense Lab presents
Analysis of the Secure Remote Password (SRP) Protocol Using CPSA
Erin Lanus, UMBC Cyber Defense Lab
12:00–1:00pm, Friday, 6 September 2019, ITE 227, UMBC
Joint work with Alan Sherman, Richard Chang, Enis Golaszewski, Ryan Wnuk-Fink, Cyrus Bonyadi, Mario Costa, Moses Liskov, and Edward Zieglar
Secure Remote Password (SRP) is a widely deployed password authenticated key exchange (PAKE) protocol used in products such as 1Password and iCloud Keychain. As with other PAKE protocols, the two participants in SRP use knowledge of a pre-shared password to authenticate each other and establish a session key. I will explain the SRP protocol and security goals it seeks to achieve. I will demonstrate how to model the protocol using the Cryptographic Protocol Shapes Analyzer (CPSA) tool and present my analysis of the shapes produced by CPSA.
Erin Lanus earned her Ph.D. in computer science in May 2019 from Arizona State University. Dr. Lanus is currently conducting research with Professor Sherman’s Protocol Analysis Lab at UMBC. Her previous results include how to use state to enable CPSA to reason about time in forced-latency protocols. Her research also explored algorithmic approaches to constructing combinatorial arrays employed in interaction testing and the creation of a new type of array for attribute distribution to achieve anonymous authorization in attribute-based systems. In October she will begin as a research assistant professor at Virginia Tech’s Hume Center in Northern Virginia. email:
