Basis Pursuit in sensor networks
Basis Pursuit (BP) finds a minimum ℓ1-norm vector z that satisfies the underdetermined linear system Mz = b, where the matrix M and vector b are given. Lately, BP has attracte...

Efficient search of music pitch contours using wavelet transforms and segmented dynamic time warping
We propose a method of music melody matching based on their “continuous” (or “time-frame-based”) pitch contours. Most previous methods using frame-based contours either ma...
