Title: Data-Centric Human Computation + From 100 Students to 100,000
Abstract: This talk will have two completely independent parts -- one related to research and the other to education.
In the first part of the talk, I'll describe our ongoing research in leveraging human computation for tasks related to data. Human computation ("crowdsourcing") augments traditional computation with the use of human abilities to solve sub-problems that are difficult for computers, e.g., object or image comparisons, information extraction, relevance judgements, and data gathering. We are addressing two different types of data-centric human computation: (1) Fundamental algorithms, such as sorting, clustering, and data cleaning, in which the basic operations (e.g., compare, filter) are performed by humans. (2) A database-system like platform in which declarative queries are posed by users, and the system orchestrates a combination of stored and crowdsourced data to answer them. Common to both areas is the need to formalize and optimize new tradeoffs among latency (humans are much slower than computers), cost (humans require real money to perform tasks), and quality (humans are inaccurate and inconsistent).
In the second part of the talk, I'll describe my recent experience teaching introductory databases to 60,000 students. Admittedly only 25,000 of them submitted their homework, and a mere 6500 achieved a strong final score. But even with 6500 students, I more than quadrupled the total number of students I've taught in my entire 18-year academic career. I began by "flipping" the way I teach my Stanford course and, as a side-effect, making all components of the course freely available online. But the big inflection point came when I offered the online course in a structured fashion with a schedule, automatically-graded assignments and exams, and most importantly a worldwide community of students (now known as a "MOOC", or Massive Open Online Course). I'll cover a variety of topics related to the massive online course, both logistical and social, while avoiding speculation on the future of higher education.

Title: One Size Fits A Bunch: The ASTERIX Approach to Big Data Management
Abstract: Like most fields, the database field has gone through various eras - a.k.a. pendulum swings - and we are currently in the era of "One Size Fits All: An Idea Whose Time Has Come and Gone". This is great news for industry sectors such as the Bubble Gum industry and the international consortium of Baling Wire manufacturers, and it is also very good news for Information Integration enthusiasts. Why? Because the current state of practice related to "Big Data" involves somehow piecing together many systems whose target sizes fit different use cases. This talk will provide an overview of the ASTERIX project at UC Irvine, a counter-cultural systems project in SoCal in which we are building a new, coherent, scalable, open-source "Big Data" software stack that we hope will solve a range of problems that today require too many piece parts to solve.
About the speaker: Michael J. Carey is an ex-long-time member of the NorCal database community.

Title: Software-Defined Networking: Introduction and Implications
Abstract: Software-Defined Networking (SDN) has all the signs of a fad: massive hype in the trade rags, an increasing number of academic papers, and widespread confusion about what SDN really means (Isn't it just OpenFlow? Isn't it all about centralization? Isn't it all just hot air?). This talk will try to dispel some of this confusion by discussing how SDN arises from a few natural abstractions for the network control plane.
About the speaker: Scott Shenker spent his academic youth studying theoretical physics but soon gave up chaos theory for computer science. Continuing to display a remarkably short attention span, his research over the years has wandered from performance modeling and networking to game theory and economics. Unable to focus on any single topic, his current research projects include cluster programming models, genomic sequence aligners, software-defined networking, and Internet architecture. Unable to hold a steady job, he currently splits his time between the U. C. Berkeley Computer Science Department and the International Computer Science Institute. His career highlight is to have once coauthored a paper with Doug Terry.

Title: Experiments in Social Computation
Abstract: What do the theory of computation, economics and related fields have to say about the emerging phenomena of crowdsourcing and social computing?
Most successful applications of crowdsourcing to date have been on problems we might consider "embarrassingly parallelizable" from a computational perspective. But the power of the social computation approach is already evident, and the road cleared for applying it to more challenging problems.
In part towards this goal, for a number of years we have been conducting controlled human-subject experiments in distributed social computation in networks with only limited and local communication. These experiments cast a number of traditional computational problems --- including graph coloring, consensus, independent set, market equilibria, biased voting and network formation --- as games of strategic interaction in which subjects have financial incentives to collectively "compute" global solutions. I will overview and summarize the many behavioral findings from this line of experimentation, and draw broad comparisons to some of the predictions made by the theory of computation and microeconomics.
About the speaker: Michael Kearns is a professor of Computer and Information Science at the University of Pennsylvania, where he is the director of the new Penn program in Market and Social Systems Engineering (www.mkse.upenn.edu). His research interests include topics in machine learning, algorithmic game theory, social networks, computational finance and artificial intelligence.

Title: AMPLab: Making Sense of Big Data with Algorithms, Machines and People
Abstract: Organizations of all types are trying to figure out how to extract value from their data. The key challenge is that the massive scale and diversity of the continuous flood of information we are faced with breaks existing technologies. State-of-the-art Machine Learning algorithms do not scale to massive data sets. Existing data analytics frameworks cope poorly with incomplete and dirty data and cannot process heterogeneous multi-format information. Current large-scale processing architectures struggle with diversity of programming models and job types and do not support the rapid marshalling and unmarshalling of resources to solve specific problems. All of these limitations lead to a Scalability Dilemma: beyond a point, our current systems tend to perform worse as they are given more data, more processing resources, and involve more people — exactly the opposite of what should happen.
To address these issues, a group of us from machine learning, systems, databases, and networking at Berkeley started a new five-year research effort called the AMPLab, where AMP stands for "Algorithms, Machines, and People". AMPLab envisions a world where massive data, cloud computing, communication and people resources can be continually, flexibly and dynamically be brought to bear on a range of hard problems by huge numbers of people connected to the cloud via increasingly powerful mobile and other client devices. We are developing a new data analytics stack that implements this vision. AMPLab's research is supported in part by Microsoft and 18 other leading technology companies, including founding sponsors Google and SAP.In this talk, I will give an overview of the AMPLab motivation and research agenda and discuss several of our initial projects. One such project, CrowdDB, is developing infrastructure to support hybrid cloud/crowd query answering systems - leveraging the very different skills, and performance, reliability, and cost characteristics of large groups of machines and large groups of people.

Title: Hardware and software synchronous design and verification with Esterel v7
Abstract: Esterel v7 is a formal language for hardware design and synthesis, with software simulation and formal property verification. Esterel v7 embodies specific time- and event-based temporal design primitives that help designing complex control behavior and lead to more efficient implementation and verification. The language also embodies data path constructs that are type-checked in a way that helps optimal bit-level-sizing. The language and semantics support single or multiple clocks, with automatic clock-gating generation in hardware linked to temporal statements. Implementation is performed by compiling into Verilog / VHDL, simulation by compiling into C / C++, and verification by compiling into the Prover SL model-checker. The semantics and implementation guarantee that simulation and verification always exactly match the hardware implementation. Esterel v7 can also be used for the efficient design and verification of pure software controllers.
Esterel v7 and its Esterel Studio IDE have been developed at Esterel Technologies from 2001 to 2009, following the former Esterel v5 academic development that started in 1983. The system has been used for production and research at Texas Instruments, ST Microelectronics, Intel, NXP, etc., with formal verification very early in the cycle. Several designs have been realized by pairing Esterel for complex control parts with C-based solutions for signal processing data path. Esterel Studio is now property of Synopsys. Its cousin synchronous technology SCADE developed by Esterel Technologies is heavily used for safety-critical software development in avionics, railways, etc.
In the talk, Professor Berry will discuss the design principles of Esterel v7 and present its main synthesis, compiling, and verification algorithms. He will give examples of application of the Esterel approach to systems-on-chip components design, and discuss the advantages and limitations of the approach.
About the Speaker: Gérard Berry is currently Director of Research at INRIA. His main area of research is the design and verification of hardware circuits and software embedded systems. He was Chief Scientist of the Esterel Technologies company from 2001 to 2009. He acted as Professor at Collège de France in 2007-2008 and 2009-2010. He is a member of Académie des sciences, Académie des technologies, and Academia Europaea.

Title: Never-Ending Learning
Abstract: What would it take to develop machine learners that run forever, each day improving their performance and also the accuracy with which they learn? This talk will describe our attempt to build a never-ending language learner, NELL, that runs 24 hours per day, forever, and that each day has two goals: (1) extract more structured information from the web to populate its growing knowledge base, and (2) learn to read better than yesterday, by using previously acquired knowledge to better constrain its subsequent learning.
The approach implemented by NELL is based on two key ideas: coupling the semi-supervised training of hundreds of diffent functions that extract different types of information from different web sources, and automatically discovering new constraints that more tightly couple the training of these functions over time. NELL has been running nonstop since January 2010 (follow it at http://rtw.ml.cmu.edu), and had extracted a knowledge base containing approximately 400,000 beliefs as of September 2010. This talk will describe NELL, its successes and its failures, and use it as a case study to explore the question of how to design never-ending learners.

Title: RAMCloud: Scalable High-Performance Storage Entirely in DRAM
Abstract: Disk-oriented approaches to online storage are becoming increasingly problematic: they do not scale gracefully to meet the needs of new large-scale Web applications, and improvements in disk capacity have out-stripped improvements in access speed. In this talk I will describe a new approach to datacenter storage called RAMCloud, where information is kept entirely in DRAM and large-scale systems are created by aggregating the main memories of thousands of commodity servers. A RAMCloud can provide durable and available storage with 100-1000x the throughput of disk-based systems and 100-1000x lower access latency. By combining low latency and large scale, RAMClouds will enable a new class of applications that manipulate large datasets more intensively than has ever been possible.

Title: Building a Commercial Deduplication Storage System
Abstract: We all hate tapes, but they have been used to store backup and archive data in data centers for several decades. In 2001, Data Domain set its mission to replace tape libraries by developing deduplication storage system products. Since 2003, Data Domain has launched several deduplication storage appliances and data replication eco-systems for data centers to replace tape libraries. These products can reduce storage footprints, WAN bandwidth requirements, and power consumptions by an order of magnitude. To date, it has deployed about 30,000 systems to about 5,000 data centers, and deduplication storage has now become the new standard for online data protection.
In this talk, I will give a retrospective overview of developing a commercial deduplication storage system for data centers, and a summary of the lessons we have learned in building and deploying a commercially successful deduplication storage product line.

Title: Web Search: Challenges and Directions
Abstract: These are exciting times for the field of Web search. Search engines are used by millions of people every day, and the number is growing rapidly. This growth poses unique challenges for search engines: they need to operate at unprecedented scales while satisfying an incredible diversity of information needs. Furthermore, user expectations have expanded considerably, moving from "give me what I said" to "give me what I want". Finally, with the lure of billions of dollars of commerce guided by search engines, we have entered a new world of "Adversarial Information Retrieval". This talk will show that the world of algorithm and system design for commercial search engines can be described by two of Murphy's Laws: a) If anything can go wrong, it will; and b) Even if nothing can go wrong, it will anyway.
About the speaker: Amit Singhal is a Google Fellow.

Title: A Case for OneSwarm
Abstract: OneSwarm is a platform for wide-scale distributed peer-to-peer applications, designed as an open-source alternative to cloud computing for sharing user-generated content. While storing and sharing data through centralized data centers offers many advantages to the system designer, it is not without its drawbacks for the rest of us: a loss of privacy, application lock-in, susceptibility to censorship, applicability to the long tail of unprofitable user-generated content, and limits on system scalability and reliability. Peer-to-peer systems to date suffer from many of these same issues, leaving us without much of an alternative. OneSwarm is our attempt to address these issues, starting with the fundamental assumption of no centralized trust — OneSwarm is not only open source, it is designed to resist being “owned”. This raises questions of incentives, user interface design, storage, privacy, and application management, that will be the focus of the talk.
About the speaker: Thomas Anderson is the Robert E. Dinning Professor of Computer Science and Engineering at the University of Washington.

Title: Future Research Directions in Computer Science
Abstract: The field of computer science is changing rapidly due to the increased power of computing, the size and complexity of problems we deal with, the merging of computing and communication, and the availability of vast amounts of information in digital form. Because of this, research in programming languages, compilers, operating systems, and algorithms that has been a major focus of researchers in the past will be supplemented by new areas. In the future we will deal with social networks, tracing the flow of ideas in the scientific literature, high dimensional data, searching, ranking, collaborative filtering and detecting changes in data or transactions before they become obvious. This talk will explore research topics in several of these areas: tracking communities in social networks, tracing the flow of ideas in scientific literature and understanding high dimensional data.

Title: A New Approach to Auctions and Mechanism Design
Abstract: Mechanism design's goal is to guarantee a given property P, defined on "state information" known only to a set of players, by leveraging the players' knowledge and rationality. Traditionally, this goal is interpreted as designing a game G such that P holds at one or more of G's equilibria. But due to collusion, as well as computational complexity and privacy concerns, traditional mechanisms may be very far from guaranteeing their desired properties.
We thus put forward a new approach to mechanism design that (1) does not rely on equilibria, (2) is resilient to collusion, and (3) harmonizes incentives with computational complexity and privacy. We exemplify our approach for revenue in combinatorial auctions.

Title: Probabilistic Models for Holistic Scene Understanding
Abstract: Over recent years, computer vision has made great strides towards annotating parts of an image with symbolic labels, such as object categories (things) or segment types (stuff). However, we are still far from the goal of providing a semantic description of an image, such as "a man, walking a dog on a sidewalk, carrying a backpack".
In this talk, I will describe some projects we have done that attempt to use probabilistic models to move us closer towards the goal. The first part of the talk will present methods that use a more holistic scene analysis to improve our performance at core tasks such as object detection, segmentation, or 3D reconstruction.
The second part of the talk will focus on finer-grained modeling of object shape, so as to allow us to annotate images with descriptive labels related
to the object shape, pose, or activity (e.g., is a cheetah running or standing). These vision tasks rely on novel algorithms for core problems in machine learning and probabilistic models, such as efficient algorithms for probabilistic correspondence, transfer learning across related object classes for learning from sparse data, and more.

Title: Morpheus: A Deep Web Search Engine
Abstract: Much attention has been paid to searching the shallow web for information visible on pages accessible to crawlers. However, information behind web forms and other kinds of interfaces is typically invisible to current crawlers, and cannot be found using current shallow web systems. It is estimated that the deep web is 500 times as large as the shallow web. Much of the deep web is data (as opposed to text) and contains transportation schedules, pricing information, availability, tardiness, and personal data.
This talk describes Morpheus, a search system oriented toward the deep web which we have built at M.I.T. The architecture of the systems will be described, and a demo given. Open issues will be considered, and efforts to "wrap" the shallow web will be explored. Finally, some of the experiences of a startup (currently in stealth mode) to commercialize Morpheus will be recounted.

Title: Building scalable and fault-tolerant enterprise search platforms
Abstract: Enterprise search has become a critical part of an organization's infrastructure. At large organizations, documents are generated at a high rate and have to be available for search within seconds. High availability and high performance for search are both essential, while the use of specialized hardware should be avoided. In this talk I will cover some of the distribution and replication techniques that we have developed in order to meet the difficult requirements.

Distinguished Professor, University of Massachusetts Amherst; Director of the Center for Intelligent Information Retrieval
Speaker: Bruce Croft
Date: 9 June 2008, 3:00-4:00pm
Title: Longer Queries, Better Answers?
Abstract: Web search engines produce effective rankings for queries consisting of a small number of keywords, within the accepted limitations of what it means for a Web page to be “relevant” to a query. On the other hand, people are perfectly capable of describing what they are looking for more precisely with a longer query. The problem is that we currently don’t know what to do with these longer queries, unless they happen to be a “factoid” query of the type used in question answering systems. Even in TREC evaluations, where query response times are not an issue, long queries generally are less effective than short queries. In this talk, I will review the approaches that have been taken with longer queries, and present two pieces of our research related to this issue; generating keyword queries from long queries and finding answers in a community-based question and answer archive.
About the speaker: W. Bruce Croft is a Distinguished Professor in the Department of Computer Science at the University of Massachusetts, Amherst, which he joined in 1979.

Speaker: Fernando Pereira
Date: 11 April 2007
Title: Learning to Analyze Sequences.
Abstract: Sequential data -- speech, text, genomic sequences -- floods our storage servers. Much useful information in these data is carried by implicit structure: phonemes and prosody in speech, syntactic structure in text, genes and regulatory elements in genomic sequences. Over the last six years, several of us have been investigating structured linear models, a unified discriminative learning approach to sequence analysis problems. I will review the approach and illustrate it with applications to parsing, information extraction, and gene finding. I will conclude with a summary of other applications and current research questions.

Speaker: Noam Nisan
Date: 26 July 2007, 12:00pm
Title: Algorithmic Mechanism Design
Abstract: One of the challenges that the Internet raises is the necessity of designing distributed protocols for settings where the participating computers are owned and operated by different owners with different goals. Over the last decade or so there has been much research that aims to address these issues using ideas taken from the micro-economic field of mechanism design. In this talk I will survey the current state of the field: how mechanism design is applied in computational settings, how far can classical ideas go, and what are the challenges for further research. Among the applications discussed will be combinatorial auctions, cost sharing, scheduling, and routing in networks.

Speaker: Raj Reddy
Date: 3 Dec 2007, 12:00pm
Title: Global Access to Information: Research Issues in Data Mining and Text Mining
Abstract: In this talk we will present research issues that arise when attempting to provide "Global Access to Information". To be true to this vision, one must also resolve the problems of Language Divide and Literacy Divide. Over 80% of the global population is not English-literate and over 20% of the population is functionally illiterate, i.e., they cannot read and understand in any language! We will use example from Million Book Digital Library projectand from a project in India to provide health information to illiterate people. Jaime Carbonell stated, about 10 years ago, that the CMU Language Technology Institute research mission is "getting the right information, to the right people, at the right time, on the right medium, in the right language and with the right level of detail". In spite of major advances in search technologies, we are not close to achieving the information society bill of rights in providing global access to iformation. This talk will provide a forum for discussion on the research agenda in Data Mining and Text Mining necessary for fulfilling this vision.
