Line graph comparing computation time (in seconds, log scale) versus data length N (log scale) for five Recurrence Quantification Analysis (RQA) methods: RQA_RP, RQA_woRP, RQA_samp, RQA_samp², and RQA microstates. The graph shows that RQA_samp and RQA microstates consistently require the least computation time, while RQA_RP requires the most, with all methods increasing in time as data length grows.
Inspired by recurrence microstates, I developed an efficient, sampling-based approach for recurrence quantification analysis, significantly reducing computation time – and, consequently, energy consumption. Published today open access. #recurrence_plot

Figure 1 is problematic – close trajectories should not evolve in opposite directions (this would also produce perpendicular diagonal lines in the #recurrence_plot). Otherwise, the paper is very interesting with cool results!
