I added the Supplementary Material of the paper to this repository (which is part of the paper but might be hard to find on the Frontiers website). Can you check it out and see if that addresses your problems?
This supplementary material addresses my questions. Thanks!
I didn't find any documentation on the data in the VitalDB dataset within PulseDB. A few clarification questions:
ABP_Lag
mean and do we need to account for it when analyzing the data? I'm assuming this lag comes from here in the paper, "PPG-ABP correlation analysis: The PPG and the ABP signals are first aligned using a lag that yields the highest cross correlation between the two signals to compensate the phase difference of the two signals and the inter-signal misalignment in the MIMIC-III database. Next, the Pearson’s correlation coefficient between the aligned signals is calculated, and the segment is rejected if the correlation coefficient is <0.9, as suggested in 46 ".CaseID
? It appears thatCaseID
is not the same asSubjectID
, as there are more unique values forCaseID
thanSegmentID
. How is this mapping done?
