Updated: 13 Nov 2013

The aim of this symposium is to provide a forum for researchers and technologists to present new ideas and contributions in the form of technical papers, panel discussions as well as real-world evaluation of many ideas in wireless communications, networking and signal processing employed to support the needs of the Information Society. This eleventh symposium will bring together various wireless communication systems developers to discuss the current status, technical challenges, standards, fundamental issues, and future services and applications. ISWCS'14 seeks to address and capture highly-innovative and state-of-the-art research from academia, the wireless industry as well as standardization advances. The scope of the conference includes a wide range of technical challenges encompassing wireless communications, information theory, quality of service support, networking, signal processing, cross-layer design for improved performance, and future wireless broadband systems. - See more at: http://www.cttc.es/2013/10/24/cttc-coorganizes-the-iswcs2014/#sthash.jmRIr40a.dpuf

Social Signal Processing Summer School - Claes Strannegård - What is it like to be a bee?

Order: Reorder
Duration: 84:17
Updated: 12 Aug 2013

Claes Strannegård is an associate professor at the Department of Philosophy, Linguistics and Theory of Science, University of Gothenburg and the Department of Applied Information Technology at Chalmers University of Technology. The ability to learn, neuroplasticity, enables honey bees to adapt to new environments and perform a wide range of cognitive tasks in those environments. Honey bees outperform artificial systems both in versatility and robustness and therefore their neurophysiology could provide valuable clues to artificial general intelligence. Reward seems to play a central role in guiding the learning process of bees, both when learning which perceptual patterns are associated with reward and which actions to take when a given perceptual pattern occurs, so as to satisfice reward. I present a graph-based computational model of memory development. In this model all learning is driven by reward. The model learns (i) memory structures representing perceptual patterns of the environment and (ii) actions that manipulate the environment. The goal is to combine automatic concept development with a variation of reinforcement learning. In social animals such as bees, part of the reward signals come from the social environment. Thus the nervous system is partly shaped by social signals. Similarly, our computational model is partly shaped by feedback signals from humans that interact with it. The human user has the options of staying passive or interfering actively by encouraging or discouraging certain kinds of behavior.

Nyquist

Updated: 10 Sep 2013

just in case you dont know what this means here is a definition he Nyquist--Shannon sampling theorem, after Harry Nyquist and Claude Shannon,[1] in the literature more commonly referred to as the Nyquist sampling theorem or simply as the sampling theorem, is a fundamental result in the field of information theory, in particular telecommunications and signal processing. Sampling is the process of converting a signal (for example, a function of continuous time or space) into a numeric sequence (a function of discrete time or space). Shannon's version of the theorem states:[2] If a function x(t) contains no frequencies higher than B hertz, it is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart. In other words, a bandlimited function can be perfectly reconstructed from a countable sequence of samples if the bandlimit, B, is no greater than half the sampling rate (samples per second). The theorem also leads to a formula for reconstruction of the original function from its samples. When the bandlimit is too high (or there is no bandlimit), the reconstruction exhibits imperfections known as aliasing. The Poisson summation formula provides a graphic understanding of aliasing and an alternative derivation of the theorem, using the perspective of the function's Fourier transform.
