Snippet: A third challenge pertains to the measurement matrix, A. In our current design, rows and columns contain similar numbers of nonzeros (Sec. IV). Therefore, each measurement provides the same signal to noise ratio (SNR). One matrix design option is to allow different rows and columns to have different numbers of nonzeros. Another is to prevent any pair of patients, n 1 and n 2 , from both having nonzero matrix entries in different rows, m 1 and m 2.....
Document: A third challenge pertains to the measurement matrix, A. In our current design, rows and columns contain similar numbers of nonzeros (Sec. IV). Therefore, each measurement provides the same signal to noise ratio (SNR). One matrix design option is to allow different rows and columns to have different numbers of nonzeros. Another is to prevent any pair of patients, n 1 and n 2 , from both having nonzero matrix entries in different rows, m 1 and m 2 , i.e., A m1n1 , A m1n2 , A m2n1 , and A m2n2 cannot all be nonzero. Refinements in matrix design will improve our estimation quality.
