INCOSE-LA Chapter Speaker Meeting
Tue, Aug 07, 2018 @ 06:30 PM - 07:30 PM
Systems Architecting and Engineering, USC Viterbi School of Engineering
Conferences, Lectures, & Seminars
Speaker: Scott Jackson, USC Systems Architecting and Engineering Program
Talk Title: A fresh look at Systems Engineering -“ What is it, how should it work
Series: INCOSE-LA Speaker Series
Abstract: Does our historical approach to Systems Engineering fit our 21st century applications? The INCOSE definition of SE was compared to the aspirations set out in SE Vision 2025 for SE as it ought to be to address modern challenges. Doing this led us to three fundamental realizations.
• Past systems were mostly deterministic, but 21st century systems are on the other hand increasingly non-deterministic, adaptive or evolutionary
• Past Systems Engineering management was implicitly based on a command and control paradigm, 21st century Systems Engineering must use a more collaborative leadership paradigm
• Past systems were largely single systems designed to solve specific problems, but 21st century systems are almost invariably networked, and are parts of complex extended enterprises with multiple, often conflicting, stakeholder objectives intimately related to complex societal challenges.
The presentation will use elements of Soft Systems Methodology to understand the implication and consequences of the paradigm shift implied by these realizations. A revised strawman definition of Systems Engineering is offered for consideration by INCOSE, showing the changes that would be required to take these and related factors into account.
The introduction to this topic will consider changes in what we mean by system. The System Definition Survey issued to INCOSE Fellows in December 2016 revealed at least five radically distinct worldviews on systems within a relatively small, but moderately representative, part of the INCOSE community. Scott will describe and analyze the survey results, and comment on differences between the responses from the Fellows and the responses to a similar survey issued to the System Science Working Group a month later. All the worldviews identified offer useful perspectives for systems engineering. Systems Engineers need the flexibility to adopt different worldviews for different situations.
This presentation reflects the work of a team of experienced INCOSE authors: Hillary Sillitto, James Martin, Regina Griego, Dorothy McKinney, Eileen Arnold, Patrick Godfrey, Dov Dori, Daniel Krob and Scott Jackson.

SERC Talks
Wed, Aug 08, 2018 @ 10:00 AM - 11:00 AM
Systems Architecting and Engineering, USC Viterbi School of Engineering
Conferences, Lectures, & Seminars
Speaker: Barry Boehm, TRW Professor, Director, Center for Systems and Software Engineering, University of Southern California
Talk Title: How to Query, Qualify and Quantify the Qualities Quagmire
Series: Successfully Applying Agile Methods for High-Criticality Systems
Abstract: Systems and software qualities are also known as non-functional requirements. Where functional requirements specify what a system should do, the NFRs specify how well the system should do them. Many of them, such as Reliability, Availability, Maintainability, Usability, Affordability, Interoperability, and Adaptability, are often called ilities, but not to the exclusion of other SQs such as Safety, Security, Resilience, Robustness, Accuracy, and Speed.
In 2012, the US Department of Defense identified seven Critical Technology Areas needing emphasis in its technology investments. One of them was called Engineered Resilient Systems. The SERC sponsor, the DoD Undersecretary for Systems Engineering, and the lead ERS research organization, the Army Engineering Research Center (ERC), held two workshops to explore what research was being addressed, and how the SERC could complement it. It turned out that the existing ERS research underway was primarily directed at field testing, supercomputer modeling, and resilient design of physical systems, and that the SERC could best complement this research by addressing the resilient design of cyber-physical-human systems, Some of the SERC universities were performing such research, such as AFIT, Georgia Tech, MIT, NPS, Penn State, USC, U. Virginia, and Wayne State. These universities have been addressing aspects of this research area as a team since 2013.
Initially, the team found a veritable quagmire of SQ definitions and relationships. For example, looking up resilience in Wikipedia, the team found over 20 different definitions of resilience, with over 10 different definitions of systems post-resilient state. The leading standard in the area, ISO-IEC 25010, had weak and inconsistent definitions of the qualities. For example, it defined Reliability with respect to the satisfaction of system functional requirements, but not its quality requirements. Some of the SERC universities had developed partial ontologies of the SQs, and exploration of alternative ontology structures identified found one that addressed not only the inter-quality relationships, but also their sources of value variation. The talk will summarize how the ontology can help systems engineers query, qualify, and quantify the relations among the system qualities, and better address key qualities such as Maintainability.
Biography: Dr. Barry Boehm received his B.A. degree from Harvard in 1957, and his M.S. and Ph.D. degrees from UCLA in 1961 and 1964, all in Mathematics. He has also received honorary Sc.D. in Computer Science from the U. of Massachusetts in 2000 and in Software Engineering from the Chinese Academy of Sciences in 2011. He is a Fellow of the ACM, AIAA, IEEE, and INCOSE, and a member of the NAE.
While at USC, he has served as the Principal Investigator on major research contracts and grants from the Office of the Secretary of Defense, DARPA, ONR, AFRL, USAF-ESC, TACOM, NASA, FAA, and NSF. He has received industry research grants from over 25 industrial organizations. His real-client software engineering project course has successfully completed over 200 projects for USC-neighborhood clients and educated over 2000 students in an integrated approach to systems engineering and software engineering. He has published over 500 papers and books, with over 50,000 citations, and a Google Scholar h-index of 81.

Electrical Engineering Seminar
Wed, Aug 08, 2018 @ 03:03 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Victor O.K. Li, The University of Hong Kong, Hong Kong
Talk Title: Bayesian Deep Learning: A Hybrid Approach to Predict Air Pollution
Abstract: Air pollution has deteriorated rapidly in many metropolitan cities, such as Beijing. Since poor air quality has clear public health impacts, accurately monitoring and predicting the concentration of PM2.5 and other pollutants have become increasingly crucial. This talk presents a hybrid approach where time series decomposition and Bayesian Long Short-Term Memory (BLSTM) are combined as a framework for air pollution forecast, based on historical data of air quality, meteorology and traffic in Beijing. LSTM has been proven to achieve state-of-the-art performance in many time series prediction applications due to its capability of memorizing long term sequential correlations. In addition, the model uncertainty estimates generated by Bayesian methods may reduce overfitting, improving the accuracy of the prediction. In our experiment, deseasonalized features are fed into BLSTM to predict the air pollution in the next 48 hours of each monitoring station in Beijing. Results show that the BLSTM framework outperforms the baseline models including SVR, STL, ARIMA, and traditional LSTM with dropout regularization.
Biography: Victor O.K. Li received SB, SM, EE and ScD degrees in Electrical Engineering and Computer Science from MIT. Prof. Li is Chair of Information Engineering and Cheng Yu-Tung Professor in Sustainable Development at the Department of Electrical & Electronic Engineering (EEE) at the University of Hong Kong.

Invited Talk in Honor of Bob Braden: "The Past and Futures of the Internet"
Fri, Aug 10, 2018 @ 01:30 PM - 03:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: David Clark, Sr. Research Scientist , MIT Computer and Artificial Intelligence Laboratory
Talk Title: The Past and Futures of the Internet
Abstract: The Internet has been such a success that for many who do not know its roots, its current form seems almost a given. It is worth looking back to the early days when Bob Braden was part of the small team of researchers who started out on this quest, and remembering how much had to be learned, and the decisions that might have been made differently. Understanding that there were defining forks in the road in the past is important as we contemplate some very important forks in the road that lie in the not too distant future. The future of the Internet is no more pre-ordained than its present form.
Biography: David Clark is a Senior Research Scientist at the MIT Computer Science and Artificial Intelligence Laboratory. He is technical director of the MIT Internet Policy Research Initiative. Since the mid-70s, David has been leading the development of the Internet; from 1981-1989 he acted as Chief Protocol Architect in this development, and chaired the Internet Activities Board. His current research looks at re-definition of the architectural underpinnings of the Internet, and the relation of technology and architecture to economic, societal and policy considerations.

NL Seminar-Reasoning about objects, their components, and their descriptors
Fri, Aug 10, 2018 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: James Mullenbach , USC/ISI
Talk Title: Reasoning about objects, their components, and their descriptors
Series: Natural Language Seminar
Abstract: How do adjectives project from a noun to its parts and other aspects? If a motorcycle is red, are its wheels red? Is a sharp knifes handle sharp? Questions like this are common sense for humans, using our understanding of the world, but difficult for computers. I will describe our process for curating and annotating a large dataset consisting of related object pairs and adjectives, and a set of experiments that aim to discover the extent to which modern approaches can learn these relationships from purely textual sources.
Biography: James is a Masters Student in Computer Science at the Georgia Institute of Technology, where he works on machine learning for healthcare using written electronic health record notes. At ISI, he is working with Jonathan May and Nanyun Peng on building a dataset and models for textual commonsense reasoning. He aims to work on NLP and ML in industry for a year or so before applying for PhD programs.

Joint INCOSE/IEEE SMCS Webinar
Wed, Aug 15, 2018 @ 12:00 PM - 12:01 PM
Systems Architecting and Engineering, USC Viterbi School of Engineering
Conferences, Lectures, & Seminars
Speaker: Thomas McDermott, Jr., Sunil Bharitkar, and Chistopher Nemeth, Stevens Institute of Technology, HP Labs, and Applied Research Associates
Talk Title: Bridging the Gulf of Execution
Series: INCOSE Speaker Series
Abstract: Research results routinely fail to survive into the development phase of Research and Development projects. This gulf of execution that blocks research findings from being realized in the development phase of many projects continues to bog down R and D practice.
Concurrent engineering was supposed to be a solution, but was it? Open innovation models were designed to bridge the gap, but have they? What is the gulf, and how did we get here? It might be a matter of professional focus. Research invests in understanding the problem, and Development invests in producing the solution. Innovation happens when these link up around people in a culture that promotes risk-taking. Or is it communication? Innovation happens when people from different disciplines or roles come together with common understanding. The issue spans multiple sectors. Large industries struggle to build an innovation culture when delivery of existing products and services is at the forefront. Universities have an innovation culture, but industry needs to adopt a systems approach to realize value from that culture. Industry-university partnerships are effective when both parties realize relationships across a broad range of university programs, from students to startups, and learn how to couple the university innovation system to the industry innovation enterprise.
Three examples from INCOSE and IEEE SMCS members will suggest ways to resolve this enduring issue.
Georgia Tech--We view this relationship as a system-of-systems model, where the industry product/service enterprise is coupled to the university innovation enterprise in a larger sociotechnical systems context, and where the relationship promotes all three innovation horizons--sustaining, disruptive, and transformational. Our experience in building such relationships at Georgia Tech indicates both parties can realize success when a range of enablers to industry-university interaction promote a range of innovation opportunities--basic and translational--over a long term partnerships. This systems-of-systems model will be presented as a general context, then generalized examples from Georgia Tech industry partnership efforts will be discussed to illustrate the model.
Applied Research Associates--Our team developed a system for DoD over 3 years to support real time decision and communication support among Burn Intensive Care Unit clinicians. This example will describe collaboration among 35 members from military healthcare professionals, to cognitive psychologists and software and machine learning developers.
HP Labs--In the Emerging Computer Lab within HP Labs, among other research areas we are involved in the areas of speech analysis and interpretation, audio signal processing in conjunction with machine learning. In this part of the webinar we will explore one research topic in audio processing that we undertook, after identifying the deficiencies on HP devices, and the challenges encountered during development. We also present examples of the solutions to overcome these challenges which have helped contribute towards a scalable deployment of the technology based off of this research.

NL Seminar-Decipherment for Universal Language Tools A case study for Unsupervised Part of Speech Induction
Fri, Aug 17, 2018 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Ronald Cardenas, USC
Talk Title: Decipherment for Universal Language Tools A case study for Unsupervised Part of Speech Induction
Series: Natural Language Seminar
Abstract: Unsupervised Part of Speech induction can be viewed as a two-steps task. The first step infers a sequence of states, while the second step maps this sequence to an actual Part-of-Speech sequence at training or testing time. Hence, this last step requires reference tagged data, a luxury low-resource target languages might not have. In this talk, we present an alternative approach to the second step, modeling it as a decipherment problem in which the ciphered text is the sequence of states and the original text we want to recover is the POS sequence. This approach requires no reference data in the target language and allows to leverage POS sequences in much richer languages. Our experiments show that our approach benefits the most from simple strategies for inferring state sequences, such as Brown clustering. This allow our method to obtain reasonable performance in low-resource and limited-time scenarios.
Biography: Ronald Cardenas is a Master's student in the Language and Communication Technologies programme at Charles University in Prague. His research interests span morphological analysis and parsing of low-resource languages. At ISI, he works with Jonatan May on developing universal language tools.

NL Seminar-T1. Constraints for Transfer Learning for Machine Translation T2.SAY YES AND: BUILDING A SPECIALIZED CORPUS FOR DIGITAL IMPROVISED COMEDY
Fri, Aug 17, 2018 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Mozhdeh Gheini, Xinyu Wang , USC/ISI
Talk Title: T1. Constraints for Transfer Learning for Machine Translation T2.SAY YES-AND: BUILDING A SPECIALIZED CORPUS FOR DIGITAL IMPROVISED COMEDY
Series: Natural Language Seminar
Abstract: T1.Can we detect the parts responsible for a generic behavior in a model to transfer it to another? In this talk, we first see why this might be a good idea, especially for low resource machine translation. Then we focus on our approach to isolating a behavior. In our case, we specifically focus on coverage during machine translation. We present our results across different languages that show how neural models try to ensure coverage.
T2. In improvised comedy, saying yes, and.. is a rule of thumb that suggests that one person should accept the other person's offer yes, and then add related information on top of that and. Collecting a yes, and.. corpus is not only helpful for building an improv agent, but can also be used for building conversational skill training tool, improving a dialogue system, etc. I will discuss the methods we have used for building such a dataset, data we have got so far and future considerations.
Biography: Mozhdeh Gheini is a last semester Computer Science master's student at USC Viterbi School of Engineering. At ISI, she works on improving neural low-resource machine translation under the supervision of Jonathan May. She will be applying for Ph.D. programs this Fall.

Speaker: Jason Lee, University of Southern California
Talk Title: Towards Theoretical Understanding of Over-Parametrization in Deep Learning
Series: Fall 2018 Joint CSC@USC/CommNetS-MHI Seminar Series
Abstract: We provide new theoretical insights on why over-parametrization is effective in learning neural networks. For a k hidden node shallow network with quadratic activation and n training data points, we show that as long as k >= sqrt(2n) over-parametrization enables local search algorithms to find a globally optimal solution for general smooth and convex loss functions. Further, despite that the number of parameters may exceed the sample size, we show that with weight decay, the solution also generalizes well.
Next, we analyze the implicit regularization effects of various optimization algorithms. In particular we prove that for least squares with mirror descent, the algorithm converges to the closest solution in terms of the Bregman divergence. For linearly separable classification problems, we prove that the steepest descent with respect to a norm solves SVM with respect to the same norm. For over-parametrized non-convex problems such as matrix sensing or neural net with quadratic activation, we prove that gradient descent converges to the minimum nuclear norm solution, which allows for both meaningful optimization and generalization guarantees.
This is a joint work with Suriya Gunasekar, Mor Shpigel, Daniel Soudry, Nati Srebro, and Simon Du.
