Effects of preprocessing (PCA) and postprocessing (smoothing algorithm) on average accuracy for inter-subject model

Inter-subject model Average accuracy [Sensitivity, Specificity] (%)
Baseline Baseline + preprocessing Baseline + postprocessing Baseline + preprocessing + postprocessing
Per-epoch swallowing detection 91.5 [36.3, 95.2] 93.5 [25, 98] 90.9 [39, 94.3] 93.3 [26.5, 97.8]
Per-swallow swallowing detection 64 [62.1, 69.6] 65.3 [52.1, 72.9] 66.4 [60, 73.1] 66.7 [51.5, 75.6]
Food intake detection 74.2 [70.7, 75.7] 59.8 [66.1, 57.5] 75.2 [67.9, 78.5] 60.1 [64.7, 58.1]
