Noise is high dimensional by definition of having energy across the spectrum. PCA provides a data-driven basis (in the sense of linear algebra) that puts as much of the low-dimensional signal as possible into a few basis elements with largest variance. Many of the gains in statistical ...
At this point, it is helpful to summarize the definition of a few terms frequently used in the analysis of waves and their solutions: • A wave is the propagation in time t and space x of a disturbance in a medium. • A signal is a physical measure (e.g., traffic density k) ...
The JPEG image, MPEG video, MP3 audio and G.7xx voice formats are widely used "lossy" methods that analyze which pixels, video frames or sound waves can be removed forever without the average person noticing (see lossy compression). GIF images have no loss of pixels but may have a loss...
I believe modern high-definition compression algorithms use quality based compression in addition to a hard bit-rate limit. This means that you tell the code the total size of the compressed video you want, and it does several passes to estimate the total size and adjust the overall quality ...
The definition of b is linked to the fractal dimension, allowing for its interpreted as the fractal dimension df37 of D(ε). Upon substitution of b = df into Eq. (1), a simplified fractal damage evolution equation for rocks is derived. $$ D(\varepsilon ) = 1 - \exp \left[ {...
the modulation frequency bin from the spectrum of the summed PSTHs. For the analysis done at the on- and off-CF bands, the same procedure is performed over the summed AN activity of all CFs within the definition of on-CF band, or over the summed AN activity of all CFs except the ...
5 Periodic function Definition: g(t) is periodic if there exists P such that g(t+P) = g(t) Period of a function: smallest constant P that satisfies g(t+P) = g(t) 6 Attributes of periodic function Amplitude: max value of g(t) in any period Period: P Frequency: 1/P, cycles ...
