The Next Generation of Neural Networks Google Tech Talks November, 29 2007 In the 1980's, new learning algorithms for neural networks promised to solve difficult classification tasks, like speech or object recognition, by learning many layers of non-linear features. The results were disappointing for two reasons: There was never enough labeled data to learn millions of complicated features and the learning was much too slow in deep neural networks with many layers of features. These problems can now be overcome by learning one layer of features at a time and by changing the goal of learning. Instead of trying to predict the labels, the learning algorithm tries to create a generative model that produces data which looks just like the unlabeled training data. These new neural networks outperform other machine learning methods when labeled data is scarce but unlabeled data is plentiful. An application to very fast document retrieval will be described. Speaker: Geoffrey Hinton Geoffrey Hinton received his BA in experimental psychology from Cambridge in 1970 and his PhD in Artificial Intelligence from Edinburgh in 1978. He did postdoctoral work at Sussex University and the University of California San Diego and spent five years as a faculty member in the Computer Science department at Carnegie-Mellon University. He then became a fellow of the Canadian Institute for Advanced Research and moved to the Department of Computer Science at the University of Toronto. He spent three years from 1998 until 2001 setting up the Gatsby Computational Neuroscience Unit at University College London and then returned to the University of Toronto where he is a University Professor. He holds a Canada Research Chair in Machine Learning. He is the director of the program on "Neural Computation and Adaptive Perception" which is funded by the Canadian Institute for Advanced Research. Geoffrey Hinton is a fellow of the Royal Society, the Royal Society of Canada, and the Association for the Advancement of Artificial Intelligence. He is an honorary foreign member of the American Academy of Arts and Sciences, and a former president of the Cognitive Science Society. He received an honorary doctorate from the University of Edinburgh in 2001. He was awarded the first David E. Rumelhart prize (2001), the IJCAI award for research excellence (2005), the IEEE Neural Network Pioneer award (1998) and the ITAC/NSERC award for contributions to information technology (1992). A simple introduction to Geoffrey Hinton's research can be found in his articles in Scientific American in September 1992 and October 1993. He investigates ways of using neural networks for learning, memory, perception and symbol processing and has over 200 publications in these areas. He was one of the researchers who introduced the back-propagation algorithm that has been widely used for practical applications. His other contributions to neural network research include Boltzmann machines, distributed representations, time-delay neural nets, mixtures of experts, Helmholtz machines and products of experts. His current main interest is in unsupervised learning procedures for neural networks with rich sensory input. Tags: google techtalks techtalk engedu talk talks googletechtalks education

Social networks and trust : NetTrust 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 collection. NetTrust targets the human element of trust. It projects how a social network can signal meaningful trust information that can make an educative browsing experience. NetTrust allows an individual to select their own trusted sources of information and rate particular sites as trustworthy (or not). NetTrust allows an individual to select their own trusted authoritative sources of information from a market of ratings agencies and combine these ratings with the reputation information from their individual social network. This paper will present the Net Trust system; the dorm-based homophily tests with implications and the undergraduate-focused user testing. Speaker: Professor L. Jean Camp Professor L. Jean Camp is the author of Trust and Risk in Internet Commerce (MIT Press), Economics of Identity Theft (Springer) and the editor of Economics of Information Security (Kluwer Academic). She has authored over one hundred works, including seventy peer-reviewed works and eighteen book chapters. In addition to presentations at peer-reviewed venues, she has made scores of invited presentations on four continents. Her service has included the Board of Directors of Computer Professionals for Social Responsibility, the Board of Governors of the IEEE Society on Social Implications of Technology, Senior Member of the IEEE, and longstanding member of the USACM.

Next Generation All-IP Telecom Networks: Quality of Service Challenges and Is... Google Tech Talks January, 14 2008 ABSTRACT The SIP-based IP Multimedia Subsystem (IMS), while recently introduced, has become one of the primary distinguishing features of the next generation of mobile telecommunication systems. IMS allows mobile operators to offer advanced value-added services - like VoIP, so-called push-to-media, video, interactive gaming, and mobile banking - to their customers timely and efficiently. Google's plans to enter the wireless world open up a world of possibilities for offering customers and businesses advanced services such as targeted location-based services and advertisements through the IMS framework. Deploying IMS, however, is a non-trivial task. The core challenge for the telecom industry has been and will be the integration of the current radio access network (RAN) and IP transport infrastructure with the IMS domain. Within standardization bodies, efforts are underway to address the issues for call setup and mobility signaling, while developing unified user profile management and Quality of Service (QoS) architectures. The real goal is a standardized, IMS-centric, end-to-end unified signaling architecture. To this end, this presentation provides an overview of IMS and QoS signaling over integrated RAN and IMS domains. By using an exemplary family media service, aspects and specifics of the end-to-end QoS invocation, control and policy enforcement, including roaming scenarios, are demonstrated. Based on laboratory measurements performed at Sprint-Nextel aided with simulations, the Post Dial Delay (PDD) delay is evaluated and some practical recommendations for delay reduction are presented. The presentation will conclude with discussion of open issues and viable solutions. This presentation should be of interest to Googlers who work on mobile related projects and intend to have a big picture of next generation mobile systems such as application development, and service and system integration with wireless operators. This presentation is based on the article S. Zaghloul, A. Jukan, W. Alanqar: "Extending QoS from Radio Access to all-IP Core in 3G Networks - An Operator's Perspective," IEEE Communications Magazine, Sept 2007.

Incremental Bayesian Networks for Natural Language Parsing Google Tech Talks August 13, 2007 ABSTRACT Natural language parsing is a particularly challenging structure prediction problem, due to the large space of output structures and the complex nature of the statistical dependencies between features of the output structures. Typically these statistical dependencies are specified by hand, but recently there has been interest in using latent variables to induce them automatically. In this talk I will present a framework for structure prediction with latent variables based on a form of Dynamic Bayesian Network called Incremental Sigmoid Belief Networks (ISBNs), and illustrate how it can be applied to parsing. Approximations to ISBNs have achieved... Tags: google howto incremental bayesian networks

How to Ensure your Network is Locked Down If you are setting up a business network security should be one of your chief concerns. Any good small business network will be protected by both hardware and software firewalls that should be configured by a trained networking professional. However, further steps should be taken to protect both the network hardware and the valuable information that it stores. Electrical power Perhaps one of the greatest threats to computer networks is power surges and voltage spikes. In fact, it is not unknown for computers, servers and peripherals on entire networks to be destroyed by power surges when they have been left unprotected. Because of this, some form of surge protector is essential that will prevent voltage spikes from damaging equipment. This should either block the surge or short the system so the voltage spike does not reach the equipment. Most networks will also use uninterruptible power supplies (UPS) to prevent brief power cuts from shutting down the network. These can ensure that the network stays up and running for anything for a few minutes to a number of hours depending on the equipment.
