Algorithmic mechanisms for reliable crowdsourcing computation under collusion
(2015)We consider a computing system where a master processor assigns a task for execution to worker processors that may collude. We model the workers' decision of whether to comply (compute the task) or not (return a bogus ...

Atherosclerotic plaque ultrasound video encoding, wireless transmission, and quality assessment using H.264
(2011)We propose a unifying framework for efficient encoding, transmission, and quality assessment of atherosclerotic plaque ultrasound video. The approach is based on a spatially varying encoding scheme, where video-slice ...

Article
Behavioral plasticity through the modulation of switch neurons
(2016)A central question in artificial intelligence is how to design agents capable of switching between different behaviors in response to environmental changes. Taking inspiration from neuroscience, we address this problem by ...

Article
Comparative evaluation of despeckle filtering in ultrasound imaging of the carotid artery
(2005)It is well-known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. The recent advancements in ultrasound instrumentation and portable ultrasound devices necessitate the need ...

Article
Comparing Different Classifiers for Automatic Age Estimation
(2004)We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

Article
A consistent velocity approximation for variable-density flow and transport in porous media
(2013)Using a finite-volume nodal-based code, we introduce a new consistent numerical scheme for approximating the seepage velocity in variable-density flow in porous media. It has been known from previous works that the lack ...

Dynamical neural networks that ensure exponential identification error convergence
(1997)Classical adaptive and robust adaptive schemes, are unable to ensure convergence of the identification error to zero, in the case of modeling errors. Therefore, the usage of such schemes to 'black-box' identification of ...
