Abstract
Recent technological advances have led to the emergence of small, low-power, and possibly mobile devices with limited on-board processing and wireless communication capabilities. When deployed in large numbers, these devices have the ability to form an intelligent network which can measure aspects and identities of the physical […]

Abstract
Ever increasing computing power and connectivity bandwidth together with falling storage costs result in an overwhelming amount of data of various types being produced, exchanged, and stored. Consequently, search emerges as a key application as more and more data is being saved.

Abstract
The problem of estimating a deterministic parameter vector from noisy measurements has countless applications in science and engineering. The overwhelmingly most popular approach to estimation in such scenarios is the maximum likelihood (ML) principle. One of the main justifications for the ML method is that under suitable regularity conditions it asymptotically achieves […]

Abstract
Increasingly, we face a number of a number of data analysis, information processing, and pattern recognition problems in very high dimensional spaces. One approach to modeling such data is to proceed with the assumption that natural data is generated by physical systems with few degrees of freedom. A consequence of […]

Abstract
Biometric recognition, or, the automatic recognition of individuals based on their biometric features, is gaining increasingly more and more attention and enjoying increasing demands in various access control and crime/terrorism prevention usages. Compared to the use of a single biometric, the use multiples biometrics offers higher performance as well as […]

Abstract
This tutorial describes a state-of-the-art method for the blind source separation (BSS) of convolutive mixtures of audio signals. Independent component analysis (ICA) is used as a major statistical tool for separating the mixtures. We provide examples to show how ICA criteria change as the number of audio sources increases. […]

Abstract
Understanding language is about extracting the “meaning” from natural language input. Although meaning is the holy grail to not only linguistics but also to philosophy, psychology, and neuroscience, [1] in the last decade a variety of practical language understanding systems have been built. Language understanding tasks include information […]

Abstract
Bayesian estimation plays a central role in many signal processing problems. These are often highly nonlinear problems for which evaluation of the exact performance is intractable. A widely used technique is to find a bound on the […]

Abstract
In both academia and industry, peer-to-peer (P2P) applications have attracted great attention. Peer-to-peer file sharing applications, such as Napster, Gnutella, Kazaa, BitTorrent, Skype and PPLive, have witnessed tremendous success among end users. And the P2P streaming applications, such as PPLive, UUSee, are on the rise. Recent statistics suggests that P2P traffic accounts […]
