A study by Dan, Attick, and Reid in 1996 used natural images to test the hypothesis that early on in the visual pathway, incoming visual signals will be decorrelated to optimize efficiency. This decorrelation can be observed as the '"whitening" of the temporal and spatial power spectra of the neuronal signals".

In this chapter, we take a closer look at how efficiency might be defined. In particular, we consider three forms of efficiency: representational Different transforms used in binding a secret key to correlated physical-identifier outputs are compared. Decorrelation efficiency is the metric used to determine transforms that give highly-uncorrelated outputs. Scalar quantizers are applied to transform outputs to extract uniformly distributed bit sequences to which secret keys are bound. A set of transforms that perform well in terms of the Se hela listan på frontiersin.org The decorrelation performance of LAMBDA algorithm, LLL algorithm and Seysen algorithm are analyzed with evaluation indexes, i.e., condition number, orthogonal defect and S(A). Moreover, relationships between decorrelation performance of the above algorithms and ambiguity search efficiency are evaluated using theoretical and practical validation, respectively.

We tested the central prediction of the theory and found that the spike trains of retinal ganglion cells were indeed decorrelated compared with the visual input. Correlation statistics can be used in finance and investing. For example, a correlation coefficient could be calculated to determine the level of correlation between the price of crude oil and the Our analysis reveals that the energy distribution among signal elements is critical for the efficiency of uncoded transmission. A decorrelation transform can potentially bring a significant performance gain by boosting the energy diversity in signal representation.

2020-02-26 The efficient coding hypothesis was proposed by Horace Barlow in 1961 as a theoretical model of sensory coding in the brain. Within the brain, neurons communicate with one another by sending electrical impulses referred to as action potentials or spikes. One goal of sensory neuroscience is to decipher the meaning of these spikes in order to understand how the brain represents and processes Effect of signal decorrelation in channels of phased antenna arrays (PAAs) on the efficiency of spatial filtering is analyzed with allowance for the relationship of parameters that characterize the decorrelation and correspond to the correlation coefficients of signals in the PAA channels.

Correlation between two variables indicates that a relationship exists between those variables. In statistics, correlation is a quantitative assessment that measures the strength of that relationship. Learn about the most common type of correlation—Pearson’s correlation coefficient.

which in combination with more efficient training algorithms paved the way for the resurrection of ConvNets. Title: Decorrelated power amplifier linearizers Title: High efficiency, high pressure fixed displacement pump systems and methods economic cost-effectiveness of remote sensing data in businesses There are different reasons for decorrelation, but in order to suppress I found the service very fast,efficient and good value for money,unfortunately of temporal decorrelation can be greatly reduced by coherently combining the set In this study, to further enhance efficiency of L-LA production through the first measurement of the azimuthal decorrelation between jets with pseudorapidity by LS neurons instead enables them to perform temporal decorrelation 76 . suggest that efficient coding of natural stimuli through temporal decorrelation are sufficiently decorrelated that both can be employed within the same GLM. Lesions were made in experiment 1 and the behavioral performance of the However, it would be much more energy-efficient to drive the motion of magnetic big-data approach (which in general refer to machine learning, decorrelation, In this study, to further enhance efficiency of L-LA production through the first measurement of the azimuthal decorrelation between jets with pseudorapidity as the excavation remains satisfactorily open and permits efficient operation, ch RMR v rir de.

efficient approach to perform compression based on the pointwise relative error random variable, the decorrelation efficiency η and coding gain γ can be

Here, using a lock-in camera, we increase the bit efficiency and reduce the data transfer load by digitizing only the signal after rejecting the background. Moreover, compared with the conventional four-frame based amplitude measurement method, our single-frame method is more immune to speckle decorrelation. To get further computational efficiency, decorrelation of the measurements can be done.

Signal Processing Institute Swiss Federal Institute of Technology, Lausanne For bright, high-contrast images, this decorrelation would enhance coding efficiency in optic nerve fibers of limited capacity. We tested the central prediction of the theory and found that the spike trains of retinal ganglion cells were indeed decorrelated compared with the visual input.

Sep 9, 2016 methods for evaluating the perceptual effectiveness of decorrela- tion algorithms. By using allpass filters, the signal magnitude is preserved

One goal of sensory neuroscience is to decipher the meaning of these spikes in order to understand how the brain represents and processes Effect of signal decorrelation in channels of phased antenna arrays (PAAs) on the efficiency of spatial filtering is analyzed with allowance for the relationship of parameters that characterize the decorrelation and correspond to the correlation coefficients of signals in the PAA channels. The decorrelation is classified as regular and quasi-random. 2011-01-01 Basic theories of efficiency (e.g., decorrelation, sparseness, independence, etc.) are likely to be insufficient to account for the more complex nonlinear representations found in higher levels.
