The Deep Rendering Model: Bridging Theory and Practice in Deep Learning
… from many layers of alternating linear and nonlinear processing units and are trained using large-scale algorithms and massive amounts of training data. The recent success of deep learning systems is impressive— they now routinely yield pattern recognition systems with near or super-human …

Implementation and evaluation of echo cancellation algorithms
… double-talk detection, finite precision effects, nonlinear processing, and howling detection and control. The use of a second adaptive filter is proposed, to reduce near-end ambient noise. Simulation results indicate that this approach can reduce the ambient noise by about 20 dB. A configuration …

On Hardware Implementation of Discrete-Time Cellular Neural Networks
… The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. Each cell has a simple function (sequence of multiply-add followed by a single discrimination) that takes an element of a topographic map and then interacts with all …

Silicon Photonics for All-Optical Processing and High-Bandwidth-Density Interconnects
… to the evolving use of silicon waveguides for nonlinear all-optical processing. The unique tight mode confinement in sub-micron cross-sections combined with the high response of silicon have motivated the development of four-wave mixing (FWM)-based processing silicon devices. The key feature of …

Functional Dynamics of Primate Retinal Ganglion Cells
… vision. The retina is the first stage in the processing of complex spatial and temporal contrast signals. The responses of retinal ganglion cells to such signals provide the means to explore such processing in the retina. Most primate retinal ganglion cells fall into two broad classes, M and …

DEEP ARCHITECTURES FOR SPATIO-TEMPORAL SEQUENCE RECOGNITION WITH APPLICATIONS IN AUTOMATIC SEIZURE DETECTION
… unacceptably high false alarm rates. Many signal processing methods have been developed over the years including time-frequency processing, wavelet analysis and autoregressive spectral analysis. Though there has been significant progress in machine learning technology in recent years, use of …
