... t a l . 9 (a) (b) Figure 8: Samples of faces from (a) the AT&T Database of Faces [17] and (b) the Essex Faces95 database [35]. The images contain variation in pose, expression, scale, and ... is for this reason that the recognition rates for wavelet/HMM are rather low for this database, ranging from 35.8% when Haar was used to 42.9% for Gabor. The recognition rates increas...

... performance. We note that the SVMs trained with 256- dimensional raw AE data had quite poor performance, where the AUC was 0.39 and 0.31 for datasets SR1 and SR2. We also examined the performance ... crucial patterns from the total AE data, as well as particular P-wave arrivals, may provide clues for distinguishing between real events and extraneous signals, thus improving the spatial acc...

To perform this antenna selection at any instantaneous channel realization, we mea- sure the channel for each antenna ... antenna using a channel estimation. More specifically, the antenna with the best channel gain is labeled as the 4th antenna, and the antenna with the second best antenna as the 3rd...
