WebCHIRP is an ensemble classi er. We run it mtimes and score a testing instance based on simple-majority, equally-weighted vote. In this paper, we use m= 7. Increasing mimproves accuracy (with diminishing gains), but at the expense of time. Although CHIRP employs some well-known ideas, the combination of them described in this paper results in a WebIt corrects the PSF distortion by adjusting radar parameters, such as carrier frequency and chirp rate, based on instant data acquisition geometry. In this case, the characteristic of signal is quite different from the constant-parameter SAR and therefore, the traditional imaging algorithms cannot be directly applied for parameter-adjusting SAR ... high magnification makeup mirror https://puremetalsdirect.com
