We used an infomax approach in a feedforward neu- ral network implemented in the frequency domain using the polynomial filter matrix algebra technique. Fast

Decorrelation is a general term for any process that is used to reduce autocorrelation within a signal, or cross-correlation within a set of signals, while preserving other aspects of the signal. A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible.

We show that that models regularized with local feature decorrelation have is no guarantee that networks with a high number of filter weights, and thus with a Regarding external connectivity and functionality, a key feature of the adaptive filter model is its use of the decorrelation algorithm, which renders it uniquely av J Nygårds · 2016 · Citerat av 12 — The decorrelation by removing the previous information can also be performed at the local estimates as in the channel filter [8]. C. Covariance Intersection. The CI av O Gustafsson · 2020 — In the first paper, we introduce a filter that removes heteroscedasticity from a decorrelation matrix, L, such that Lεt becomes a sequence of uncorrelated.

Decorrelation filter

Withperfect decorrelation, the performance of the algorithm is independent ofthe signal statics. For RLS the dimension of the decorrelation matrix is equal to the filter length. For large filters this implies a high complexity.

Wrapped phase maps obtained using interferometric speckle techniques are often corrupted with high-frequency noise, typically due to speckle decorrelation (Aebischer and Waldner, 1999). Image processing using a low-pass averaging filter is often used to reduce the noise content. A low-pass filter kernel typically takes the form

Aug 2, 2012 Note that this high-frequency effect is absent in networks with more realistic low- pass filtering synapses (Fig. 2 C,D) and in purely inhibitory

Amplitude based decorrelation is where the input signal is divided between the output signals based on frequency i.e. even frequencies in the one output signal and odd frequencies in the second output signal. decorrelation filter subtracts the effect of channel distortion in the log-spectral domain and normalizes an unknown channel from the viewpoint of the linear-spectral domain.

A high-pass filter allows high frequencies to pass but cuts, or attenuates, frequencies below a thresho While your vacuum cleaner must have a vacuum bag, a motor, a hose, and a strong agitator brush, without a good vacuum filter you will just be circulating dust.

Since the performance of the usually applied LMS adaptation suffers from correlations of the input In this study the feasibility and performance of time variable decorrelation (VADER) filters derived from covariance information on decadal Gravity Recovery and Climate Experiment (GRACE) time series are investigated. The VADER filter is based on publicly available data that are provided by several GRACE processing centers, and does not need its own Level-2 processing chain. The objective of this research is to create an ensemble of decorrelation filters that, when combined with a specially treated B-Format Room Impulse Response (RIR), will approximate the expected measurements on a real array of outward-facing cardioid microphones in an acoustic diffuse field. 2021-03-22 Since the introduction of feedforward-feedback comb allpass filters by Schroeder and Logan, its popularity has not diminished due to its computational efficiency and versatile applicability in artificial reverberation, decorrelation, and dispersive system design.
