We multiply the first equation by – 3, and add it to the second equation. − 3 x − 9 y = − 21 3 x + 4 y = 11 − 5 y = − 10. By doing this we transformed our original system into an equivalent system: x + 3 y = 7 − 5 y = − 10. We divide the second equation by – 5, and we get the next equivalent system.

Web1 jan. 1984 · A modified version of Tabu Search algorithm is utilized to determine a precise estimation of row support and then joint sparse samples are reconstructed using MMSE criterion. The proposed approach is more robust to the sparsity order variations and noise uncertainty, in comparison with the conventional MMV problem solvers. WebDensity compensation can significantly increase the γ (Fig. 5) thus potentially speeds up the iterative reconstruction since the convergence speed is proportional to β-1 according to Eq. (10), indicating that the largest β = γ guarantees fastest convergence. In practice, we tested the reconstruction in MATLAB with and without density compensation on a computer …

Web26 jan. 2024 · A key concept in probability-based sampling is that if survey respondents have different probabilities of selection, weighting each case by the inverse of its probability of selection removes any bias that might result from having different kinds of people represented in the wrong proportion.
