Identifying and eliminating noisy samples from the manifold via the SSMM results in a statistically significant improvement in area under the receiver operator characteristic curve (AUC), 0.832 ± 0.048 with removal of noisy samples compared to a AUC of 0.779 ± 0.075 without removal of samples.
We then show how an adapted ensemble of STRFs can better detect speech in unseen noisy environments compared to an unadapted ensemble and a noise-robust baseline.
Again, the local block-matching BM3D estimates show a significantly increased fidelity compared to the noisy input images.
The number of spontaneous body movements and sleep stage changes per night showed an increase during the more quiet nights as compared to the noisy nights.
DOI: http://dx.doi.org/10.7554/eLife.06444.011 Our analysis suggests that the deficit in grid firing in deterministic compared to noisy networks reflects a failure of attractor states to emerge.
Experiments with a large number of observers have demonstrated that a peak signal-to-noise-ratio (PSNR) increase by 3 dB (or, equivalently, MSE reduction twice) because of filtering does not guarantee improvement of filtered image visual quality compared to original noisy one [38].
Based on isolated word recognition experiments conducted in 15 real car environments, the proposed adaptive regression approach shows an advantage in average relative word error rate (WER) reductions of 52.5 and 14.8, compared to original noisy speech and ETSI advanced front end, respectively.
As time increases, the linear trajectory of the Kalman filter results in more disparate variable values between nonprogressing and progressing instances compared to the "noisy" trajectories in the raw measurements data set.
Subjects in the Hidden-Hidden (noise) condition did not reach significantly more often for the silent piece compared to the noisy piece (Wilcoxon T = 23, N = 8, P = 0.539).
To provide better visual quality of a filtered image compared to the corresponding noisy one, it is necessary to ensure that PSNR improvement because of filtering is, at least, 3...6 dB (the smaller PSNR for noisy image, the larger PSNR improvement should be).
