Speaker: Dr. Christos Faloutsos, Carnegie Mellon University
Talk Title: Large Graph Mining: Patterns, Cascades, Fraud Detection, and Algorithms
Series: Energy Informatics Distinguished Seminar Series
Abstract: Given a large graph, like who-calls-whom, or who-likes-whom, what behavior is normal and what should be surprising, possibly due to fraudulent activity? How do graphs evolve over time? How does influence/news/viruses propagate, over time? We focus on three topics: (a) anomaly detection in large static graphs (b) patterns and anomalies in large time-evolving graphs and (c) cascades and immunization.
For the first, we present a list of static and temporal laws, including advances patterns like 'eigenspokes'; we show how to use them to spot suspicious activities, in on-line buyer-and-seller settings, in FaceBook, in twitter-like networks. For the second, we show how to handle time-evolving graphs as tensors, how to handle large tensors in map-reduce environments, as well as some discoveries such settings.
For the third, we show that for virus propagation, a single number is enough to characterize the connectivity of graph, and thus we show how to do efficient immunization for almost any type of virus (SIS - no immunity; SIR - lifetime immunity; etc)
We conclude with some open research questions for graph mining.

Talk Title: Revolutionizing Medical Device Design
Abstract: The vision of the MIT Medical Electronic Device Realization Center (MEDRC) is to revolutionize medical diagnostics and treatments by bringing health care directly to the individual and to create enabling technology for the future information-driven healthcare system. This vision will in turn transform the medical electronic device industry. Specific areas that show promise are wearable or minimally invasive monitoring devices, medical imaging, portable laboratory instrumentation, and the data communication from these devices and instruments to healthcare providers and caregivers.
Rapid innovation in miniaturization, mobility, and connectivity will revolutionize medical diagnostics and treatments, bringing health care directly to the individual. Continuous monitoring of physiological markers will place capability for the early detection and prevention of disease in the hands of the consumer, shifting to a paradigm of maintaining wellness rather than treating sickness. Just as the personal computer revolution has brought computation to the individual, this revolution in personal medicine will bring the hospital lab and the physician to the home, to emerging countries, and to emergency situations. These system solutions containing state-of-the-art sensors, electronics, and computation will radically change our approach to health care. This new generation of medical systems holds the promise of delivering better quality health care while reducing medical costs.
In this talk I will introduce the research directions of the MEDRC and discuss the circuit and system design issues and clinical measurements from selected MEDRC projects highlighting wearable monitoring.
Biography: Charles G. Sodini received the B.S.E.E. degree from Purdue University, in 1974, and the M.S.E.E. and the Ph.D. degrees from the University of California, Berkeley, in 1981 and 1982, respectively.
He was a member of the technical staff at Hewlett-Packard Laboratories from 1974 to 1982, where he worked on the design of MOS memory. He joined the faculty of the Massachusetts Institute of Technology, in 1983, where he is currently the LeBel Professor of Electrical Engineering. His research interests are focused on medical electronic systems for monitoring and imaging. These systems require state-of-the-art mixed signal integrated circuit and systems with extremely low energy dissipation. He is the co-founder of the Medical Electronic Device Realization Center at MIT.
Along with Prof. Roger T. Howe, he is a co-author of an undergraduate text on integrated circuits and devices entitled âMicroelectronics: An Integrated Approach.â He also studied the Hong Kong/South China electronics industry in 1996-97 and has continued to study the globalization of the electronics industry.

NL Seminar-Learning To Simplify Text One Sentence at a Time
Fri, Apr 24, 2015 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: David Kauchak , Pomona College
Talk Title: Learning To Simplify Text One Sentence at a Time
Series: Natural Language Seminar
Abstract: Information can now be found on almost any topic ranging from news to do-it-yourself guides to health-related articles. Unfortunately for readers, the complexity and readability of these texts can vary widely. Even if the concepts of an article are accessible, the language and structure of the text can prohibit a person from understanding these concepts.
Text simplification techniques are aimed at reducing the reading and grammatical complexity of text while retaining the meaning and are one approach to increasing information accessibility. Motivated by both corpus analyses and human experiments, I will introduce a number of recent text simplification techniques ranging from semi-automated approaches, that require a human in the loop, to automated approaches, including word-level, phrase-level and syntax-level models.
Biography: David Kauchak is currently an assistant professor in the Computer Science Department at Pomona College. Previously, he was at Middlebury College and has worked at Google, ISI, PARC and Adchemy. He received his Ph.D. in Computer Science from University of California, San Diego.

Talk Title: Lessons from the 2011 Tohoku Earthquake Focused on Ground Motion Characteristics and Building Damage
Abstract:
This paper describes lessons from the Tohoku earthquake focused on the building damage in relation to the observed ground motion characteristics from the engineering view points of the countermeasures against earthquakes. Although buildings with appropriate seismic retrofit were mostly escaped from free of damage,which indicates the effectiveness of the seismic reinforcement, it is suggested that total balance of the structural elements, the non-structural elements, and the equipment need to be considered. Also, the balance of foundation
and the superstructure for the comprehensive seismic performance of the whole building needs to be achieved. It
is important to investigate cumulative building damage for long-duration ground motion and seismic micro-zoning.
Keywords: The 2011 Tohoku Earthquake, ground motion, building damage, earthquake countermeasures
1 Introduction
A huge earthquake occurred in the Pacific Ocean off the coast of Miyagi, Japan on March 11, 2011 and caused huge physical damage and loss of life. The moment magnitude (Mw) of this earthquake, is 9.0, the largest recorded in Japan since modern seismograms became available. The fault plane has dimensions of 450km by 200km. The earthquake was followed by many aftershocks and also induced some other earthquakes.
The huge earthquake caused not only tremendous tsunami damage but also structural damage due to the severe ground motion which continued for sucha long duration. This earthquake has been named the 2011 off the Pacific coast of Tohoku Earthquake
(indicated as âthe 2011 Tohoku earthquakeâ hereafter).
Although the 2011 Tohoku Earthquake took the human lives of about 18,000 persons mainly by tsunami, which closed up the evacuation problem, the status of vibration damage and lessons from the huge earthquake should be importantly informed for
countermeasures of urban and buildings against for the earthquakes in the future.
On March 11, 2011, the author experienced the severe shaking at 11th floor of 13-story building(seismic control building with oil damper braces) at Aobayama campus of Tohoku University in Sendai,Japan. From next day, the author started quick
damage survey and investigated ground motion characteristic and building damage and contributed to publish the damage survey reports by AIJ1) and summarized the lessons of the Tohoku earthquake focused on ground motion characteristics and
building damage 2). The author also contributed to the development and utilization of Earthquake Early Warning (EEW) system. The status of the EEW utilization during the Tohoku earthquake was reported together with the raised problems3). The author also has contributed recovery and reconstruction activities of local governments.
In this paper, lessons from the 2011 Tohoku earthquake focused on the building damage in relation to the observed ground motion
characteristics are described from the engineering view points of the countermeasures against the expected earthquakes in other area of Japan and other countries all over the world.
First, the observed ground motion characteristics are described regarding the observed high acceleration record, the impact of long-duration motions, and site dependent ground motions. Then, specific features of building damage are described.
