Table 3.

Classification results for synthetic LMAP periodic records for different N and m values. The classes were studied in pairs, 01, 02, and 12. These results should be compared to results in Table 2, where the same dataset was used, but using the entire length. With lengths as short as 200 samples, results are almost the same achieved with the complete records. More difficulties were found to separate groups 1 and 2, also in line with the results using N=1000.
