Figure 2From: Exact reconstruction of gene regulatory networks using compressive sensingReducing coherence for a linear system. (Example 2) (A) the sensing matrix Ω∈ R 20 × 25 , without (top left) and with transformation Ψ (top right) and the corresponding coherence distribution (bottom) (B) reconstruction result (left) L1 (middle) L2 with Ω (right) l 1 optimization with Ω Ψ (CS) where x-axis represents indices of q∈ R 25 and y-axis represents coefficient of q (a.u). By reducing coherence of the sensing matrix with transformation, we can recover the exact structure in (B) (right). However, both L1 and L2 fail to recover the exact structure.Back to article page
