CS Colloquium: Varun Kanade (Fondation Sciences Mathématiques de Paris) - Distributed Online Learning
Thu, Apr 16, 2015 @ 09:45 AM - 10:50 AM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Varun Kanade, Fondation Sciences Mathématiques de Paris
Talk Title: Distributed Online Learning
Series: CS Colloquium
Abstract: The massive amount of data involved in modern information processing systems necessitates the use of new paradigms to effectively handle data. One such paradigm is the design of machine learning algorithms that interact with data in an online fashion, i.e., data used to make predictions is received little at a time. In addition, such algorithms may be implemented on distributed systems, resulting in a tradeoff between communication cost and prediction accuracy. In this talk, I will present a classical question in the context of online learning, the so-called experts problem. The goal in this problem is to design a prediction strategy over a set of actions in the face of uncertainty that is guaranteed to perform almost as well as the best single action in hindsight. This is a fundamental question with several applications such as drug testing, network routing, and online advertising. I will discuss the new challenges that arise when implementing algorithms for this problem in a distributed setting and present a novel algorithm that achieves a non-trivial tradeoff between prediction accuracy and communication.
The lecture will be available to stream HERE.
Biography: I am now a postdoctoral fellow at ENS through the Fondation Sciences Mathématiques de Paris (FSMP). Before this I was at UC Berkeley as a Simons Fellow. I completed my Ph.D. at Harvard University, and was extremely fortunate to have had Leslie Valiant as my adviser. Before joining Harvard, I was a graduate student at Georgia Tech, where I was working with Adam Kalai (now at Microsoft Research). I obtained a B.Tech at the Indian Institute of Technology, Bombay in Mumbai, India.

CS Colloquium: Tintri Tech Talk - Architecture in the hidden world of enterprise infrastructure
Thu, Apr 16, 2015 @ 04:00 PM - 05:30 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Ken Klein, Tintri
Talk Title: Architecture in the hidden world of enterprise infrastructure
Series: CS Colloquium
Abstract: The CEO - Ken Klein, USC alumnus and trustee - and a key engineer from Tintri, a successful storage virtualization startup will be visiting us on Thursday at 4pm in EEB 248 to meet students and tell us about their company and the interesting technical challenges they face. Please join us!
Intro Talk Abstract
A new model for IT is here - where virtualized applications are the norm, public and private clouds are the new modes of data access, and traditional storage is 20 years overdue for a shakeup. Enterprises are still bound by the same tedious, time-consuming, blind, antiquated storage solutions that don't address the most important dynamics of IT - the dynamic nature of data in a virtualized world.
You probably know a lot about the software and hardware in your iPhone, and something about the software and hardware that runs Google search, but do you know what kind of infrastructure is used at Time Warner or Chevron?
Most of the world's infrastructure actually looks more like Time Warner and Chevron than an iPhone or Google search, but because of fierce competition and huge budgets, most enterprise infrastructure vendors keep details of this world hidden, perhaps only revealing them to bigger customers while under NDA. However, today's enterprise infrastructure is very different from either consumer or Google-like infrastructure and is changing more rapidly than ever before.
In this talk I'll give you a glimpse into the dynamic and less conspicuous world of the enterprise by talking about the architecture of Tintri's application centered storage system. Because Tintri was architected around the modern datacenter, it is impossible to discuss our architecture without also discussing three disruptions that are reforming the enterprise:
Flash is reshaping the way we think about and use storage.
Virtualization and containerization have changed our compute and IO paths and our management frameworks.
Private cloud is renegotiating the contract between infrastructure and applications.
Come get a rare peek into modern enterprise infrastructure architecture!
Biography: Ken Klein is Chairman of the Board and Chief Executive Officer of Tintri, the leader in smart, application-aware, storage for the enterprise and the cloud. A software industry veteran with over 25 years of experience, he was previously president of Wind River, an Intel subsidiary subsequent to the sale to Intel Corporation for $1B. Prior to that he was Chairman, CEO, and president of Wind River where he was responsible for the management of 1,900 employees and nearly $400M in revenues. Before that, Ken served as Chief Operating Officer and a Board member of Mercury Interactive for 12 years. Klein and his team built Mercury from a pre-revenue startup into a software powerhouse with a peak market capitalization of $15B, 2,150 employees, operations in 35 countries, and membership in the NASDAQ 100 and S&P 500. The team went on to grow the company to nearly $1B in annual revenue and sell to Hewlett-Packard for $5B. Before his tenure at Mercury, Klein held various engineering, marketing, and management roles at Interactive Development Environments, Daisy Systems, and Hughes Aircraft Company.
Mr. Klein earned a bachelor of science degree in electrical engineering and biomedical engineering from the University of Southern California. He is a USC Distinguished Alumnus, member of the USC School of Engineering Board of Councilors, founder of USC's Klein Institute for Undergraduate Engineering Life (KIUEL), and a USC Trustee.
Brandon Salmon Bio:
Brandon Salmon has been working in systems and storage for over twelve years. He has a Ph.D in computer engineering from Carnegie Mellon University and a bachelors in computer science from Stanford. He has worked at Microsoft, VMware and Intel in the past. As the 6th engineer at Tintri he designed and built significant portions of both the core Tintri filesystem and integrations with private cloud environments. He now works in the Office of the CTO investigating market changes and new technologies.
Tintri Mission:
Tintri has created a different world. A world of smart storage that sees and learns and adapts, removing the opacity of traditional storage products, anticipating changes and needs before they arise. A world where simplicity and transparency replace complexity and brute force, all while delivering the return on investment required by business leaders.
Tintri builds smart storage that sees, learns, and adapts, enabling IT organizations to focus on virtualized applications and business services instead of managing storage infrastructure. Named a "Visionary" in Gartner's 2014 Magic Quadrant for General-Purpose Disk Array, Tintri is the only storage platform in the industry that provides virtual machine-level storage management, data protection, analytics, quality of services, and automation, with all flash performance. Addressing a TAM which IDC estimated to reach $17 billion in 2017, Tintri is fundamentally changing how companies deploy virtualized workloads in their data centers and in the cloud.
Tintri eliminates the need to overprovision storage for performance to meet SLA or QoS levels - a common practice with conventional storage which dramatically increases CAPEX, OPEX, and storage footprint. Every step in the Tintri experience is designed to be profoundly simple - what used to take days and hours to accomplish now takes minutes.
