PPG-DaLiA data in MATLAB format

This version of the PPG-DaLiA dataset This is a version of the PPG-DaLiA dataset in MATLAB format. Whilst the PPG data in the original dataset (see below for details) was provided in .pkl format, this version has been created by importing the data into Matlab. In addition, in this version the data are split according to individual activities. We used this version when analysing the performance of PPG beat detectors using the ppg-beats toolbox (which runs in Matlab). It may also be useful to other researchers too. This version was created from the original dataset by following the process described here. The original dataset from which it was derived (and which should be credited whenever using the dataset) The PPG-DaLiA dataset is publicly available here: https://doi.org/10.24432/C53890 As detailed at that page, the dataset was created by Attila Reiss, Ina Indlekofer, and Philip Schmidt, and is distributed under a CC BY 4.0 License.
