“…Also, it can be noticed that variation-stable approach does not affect the performances for the single-session case while it boosts the performances for the two-sessions scenario which is our main focus (covered in 4.2 section). The best performances outperform other recent works which were 1% for PRRB [8], 17.4% for TROIKA [21] and 1% for Biosec1 [17] in avg EER. Thus, we can conclude that our verification system works well even in different databases with various conditions.…”

“…Later, fully connected layer is appended with sigmoid and binary cross entropy is used to give the classification result. The model was inspired and extended from [10,17] while the hyperparameters are tuned according to the performances in all used databases. In addition, L2 regularization and 10-fold cross validation were used to control overfitting.…”

“…It is possible to divide the methods for PPG-based biometric recognition into three categories [13]: i) methods based on algoritmic approaches [2,32,31,35,10]; ii) methods based on handcrafted features and machine learning classifiers [14,29,5,18,19,36,33,37,25,22]; iii) methods based on DNNs [17,26,9,1,24,13].…”

“…Therefore, recent studies in the literature analyzed and proved the discriminability of PPG signals as biometric traits. Furthermore, empirical evaluations proved that PPG has sufficient stability for short periods of time [13].…”
