a, Boxplots showing the distribution of timing jitters relative to real spikes (electrophysiology) of all inferred spike pairs before (N = 2031) and after (N = 2574) denoising. b, Histograms showing the probability distributions of timing jitters before and after denoising. The two probability distributions were verified to be equivalent by Kolmogorov–Smirnov test (one-side, P ≤ 0.01, N = 2031 for raw data, N = 2574 for DeepCAD enhanced). c, Distributions of timing jitters at different input noise levels (Raw data, N = 326 for low-SNR, N = 689 for medium-SNR, N = 1016 for high-SNR; DeepCAD enhanced, N = 545 for low-SNR, N = 880 for medium-SNR, N = 1149 for high-SNR). d, Distributions of timing jitters at different baseline spike rates (Raw data, N = 663 for low spike rate, N = 766 for medium spike rate, N = 602 for high spike rate; DeepCAD enhanced, N = 1095 for low spike rate, N = 837 for medium spike rate, N = 642 for high spike rate). Baseline spike rates were calculated with 2 s binning time. All timing jitters were divided into three groups, that is low spike rate (baseline spike rate≤2.0 spk/s), medium spike rate (2.0 spk/s <baseline spike rate≤3.5 spk/s), and high baseline spike rate (baseline spike rateå 3.5 spk/s). These timing jitters were caused by the spike inference algorithm. Boxplots were plotted in standard Tukey box-and-whisker plot format with outliers indicated with small black dots.
