The relationship between a neuron's complex inputs and its spiking output defines the neuron's coding strategy. This is frequently and effectively modeled phenomenologically by one or more linear filters that extract the components of the stimulus that are relevant for triggering spikes and a nonlinear function that relates stimulus to firing probability. In many sensory systems, these two comp...

This paper reports the results of a comparison between a new class of architectures, called transport-triggered architectures, and traditional architectures, called operation-t~iggered architectures. It does this comparison by means of the MOVE-i860, which is a transport-triggered approximation of the i860. Several benchmarks are scheduled for the MOVE-i860 by a software pipelining scheduler. B...

This article presents a review of reverse correlation in neurophysiology. We discuss the basis of reverse correlation in linear transducers and in spiking neurons. The application of reverse correlation to measure the receptive fields of visual neurons using white noise and m-sequences, and classical findings about spatial and color processing in the cortex resulting from such measurements, are...

The spike-triggered average stimulus introduced in chapter 1 is a standard way of characterizing the selectivity of a neuron. In this chapter, we show how spike-triggered averages and reverse-correlation techniques can be used to construct estimates of firing rates evoked by arbitrary time-dependent stimuli. Firing rates calculated directly from reversecorrelation functions provide only a linea...

This article presents a method for estimating and optimizing a customizable system level architecture in the early phase of design. The model has been implemented in MATLAB. The methodology is interconnect centric and the worst case wire path has been used for calculating the overall delay of the logic. The system has been divided into different architectural blocks and the modeling method of e...

The present study evaluates the effects of syrup concentrations of natural raisin microflora culture on the characteristics of sourdough and sourdough bread. The original total titratable acidity (TTA) of the starter solutions were between 10.30 and 10.45 mL, after 96 hours of incubation, the TTA of the starter solution increased to 11.30-11.85 mL. The greatest pH decrease and TTA increase occu...

Reverse-correlation is the most widely used method for mapping receptive fields of early visual neurons. Wiener kernels of the neurons are calculated by cross-correlating the neuronal responses with a Gaussian white noise stimulus. However, Gaussian white noise is an inefficient stimulus for driving higher-level visual neurons. We show that if the stimulus is synthesized by a linear generative ...

The increasing availability of the high spatial resolution satellite images has provided a new data source for building extraction. This paper proves the concept of object oriented classification using high-resolution satellite data (Cartosat-1 satellite data fused with IRS-1C, LISS IV data) for automatic building extraction using eCognition software. In this study, the overall accuracy of clas...

We employed a white-noise velocity signal to study the dynamics of the response of single neurons in the cortical area MT to visual motion. Responses were quantified using reverse correlation, optimal linear reconstruction filters, and reconstruction signal-to-noise ratio (SNR). The SNR and lower bound estimates of information rate were lower than we expected. Ninety percent of the information ...

This paper reports the result of a comparison between reduced instruction set computing and the transport triggered architecture. Because of the simplicity and efficiency of the transport triggered architecture, its processor requires less execution cycles compared to the OpenRisc processor. This paper also presents a case study about designing an Architecture Definition File for a transport tr...
