ROC curves of the reconstructed edges at different r and noise levels. ROC curves of original Z⁰ (dashed lines) and trimmed Z¹ (solid lines) are used to assess the performance of network trimming on a synthetic data set at false connection rate = 0.20 for low (A&C) and high (B&D) noise levels, 0.1 and 0.5 respectively. Performance was assessed for various numbers of data points; r = 3 (red), 6 (gold), 9 (green), 15(blue), and 21(black). The rates on the axis are calculated based on counting all edges (A&B) or only important edges (C&D).
