Descripción: Google Tech Talks February, 28 2008 ABSTRACT NetTrust is a system that embeds social context in browsing by combining individual histories, social networks, and explicit ratings. NetTrust combines an implicit and explicit means of data collection. This trust based system uses shared browsing histories from a user's self-selected social networks to create both explicit and implicit data collectio...

Descripción: Google Tech Talks August 28, 2008 ABSTRACT Transportation accounts for 40% of the CO2 emissions in the state of California. Excluding electricity generation, liquid and gaseous hydrocarbon fuels comprise over 60% of US energy consumption. For many applications, these fuels will continue to be the most economical and highest performance energy source for decades to come even with rising petr...

Descripción: Google Tech Talks June, 4 2008 ABSTRACT We present a novel technique that speeds up state-space exploration (SSE) for evolving programs with dynamically allocated data. SSE is the essence of explicit-state model checking and an increasingly popular method for automating test generation. Traditional, non-incremental SSE takes one version of a program and systematically explores the states reacha...

Descripción: Google Tech Talks March, 24 2008 ABSTRACT Yang Li - RESEARCH SCIENTIST Pervasive or ubiquitous computing (ubicomp) applications can support people's everyday activities in the physical world by leveraging advances in sensor technologies and computing infrastructures. Designing ubicomp applications is challenging because our everyday activities are more complex, dynamic and less structured than ...

Descripción: Google Tech Talks February, 22 2008 ABSTRACT Digital identity management (DIM) has emerged as a critical foundation for supporting successful interaction in today's globally interconnected society. It is crucial not only for the conduct of business and government but also for a large and growing body of electronic or online social interactions. Digital identity management is usually coupled with...

Descripción: Google Tech Talks April, 23 2008 ABSTRACT This practical session on meditation teaches the technique of awakening the subtle energy from the position of the nervous system and the energy centers using positive affirmations to attain self-realization. Objectives: •Understand the mechanism which causes stress in life and at work •To gain control and mastery over stress •To release the energy ...

Descripción: Google Tech Talks November, 13 2007 Suppose you have a passion for items of a certain type, and you wish to start a recommender system around those items. You want a system like Amazon or Epinions, but for cookie recipes, local theater, or microbrew beer. How can you set up your recommender system without assembling complicated algorithms, large software infrastructure, a large community of contr...

Descripción: Google Tech Talks March, 20 2008 ABSTRACT Clustering is the task of finding groups in data. While traditional clustering algorithms typically measure similarity between objects by considering all attributes/features/dimensions of data objects, projected clustering algorithms attempt to find clusters that may exist only in subspaces, i.e., subsets of attributes. The problem of finding projected c...

Descripción: Google Tech Talks January, 31 2008 ABSTRACT Professional satisfaction is a question of creating what you want, not just waiting for it to appear. This tech talk, by one of the country's leading career coaches, shows how the process works. From my recent book: "The process of creating a life that works for you does not unfold logically. It proceeds in fits and starts, involves unlearni...

Descripción: Google Tech Talks June 14, 2008 ABSTRACT Increasingly, R users have access to multiprocessor machines or multiple-core CPUs. However, base R does not natively support parallel processing; this can force R users to wait while computationally intensive work is done on a single processor or core and other processors or cores lie idle. NetWorkSpaces for R (NWS-R) is a Python-based tuple coordin...

Descripción: Google Tech Talks March, 26 2008 ABSTRACT Timothee Cour - Research Scientist Movies and TV are a rich source of highly diverse and complex video of people, objects, actions and locales "in the wild". Harvesting automatically labeled sequences of actions from video would enable creation of large-scale and highly-varied datasets. To enable such collection, we focus on the task of recovering scen...

Descripción: Google Tech Talks June, 26 2008 ABSTRACT The Semantic Web presents the vision of a distributed, dynamically growing knowledge base founded on formal logic. Common users, however, seem to have problems even with the simplest Boolean expression. So how can we help users to query a web of logic that they do not seem to understand? One frequently proposed solution to address this problem is the us...

Descripción: Google Tech Talks January, 29 2008 ABSTRACT We present an algorithm to convert standard digital pictures into 3-d models. This is a challenging problem, since an image is formed by a projection of the 3-d scene onto two dimensions, thus losing the depth information. We take a supervised learning approach to this problem, and use a Markov Random Field (MRF) to model the image depth cues as well ...

Descripción: Google Tech Talks December, 11 2007 In elections employing electronic voting machines, we have observed that poor procedures, equipment failures, and honest mistakes pose a real threat to the accuracy of the final tally. The event logs kept by these machines can give auditors clues as to the causes of anomalies and inconsistencies; however, each voting machine is trusted to keep its own audit and...

Descripción: Google Tech Talks January, 7 2008 ABSTRACT Modern software pervasively uses structurally complex data, for example web-traversal code operates on graphs that encode web pages, and IDEs manipulate program representations such as abstract syntax trees. The standard approach to generating test suites for such software, manual generation of the inputs in the suite, is tedious and error-prone. This ...

Descripción: Google Tech Talks February, 21 2008 ABSTRACT It is will be too costly to design many of these chips at the polygon or even gate level, so they must be highly programmable. Furthermore, they should not just be FPGAs as we now know them because with that many transistors, we should specialize more for power efficiency. I envision FPGA-like chips where the computational elements combine CPUs with m...

Descripción: Google Tech Talks February, 29 2008 ABSTRACT I will present recent work for acquiring, rendering, and displaying photoreal models of people, objects, and dynamic performances. I will overview image-based lighting techniques for photorealistic compositing and reflectance acquisition techniques which have been used to create realistic digital actors in films such as "Spider Man 2" and "Superman R...

Descripción: Google Tech Talks July 7, 2008 ABSTRACT Urbi is a middleware for concurrent and distributed programming, based on a new parallel and event-driven script language called 'urbiScript'. Using a familiar and easy-to-use syntax, the language offers several concurrent abstractions rooted in the language semantics, together with an integrated scheduler and a distributed component architecture cal...

Descripción: Google Tech Talks June 14, 2008 ABSTRACT Seattle Conference on Scalability: Scalable multiprocessor programming via transactional memory As power restrictions have limited performance advances in a single core, new generations of processors are providing a steadily increasing number of cores on a single die. Effectively utilizing such processors requires that programmers write concurrent...
