Table 2 Confusion matrix depicting the bite detection performance of EXI using the EaC dataset.

From: Assessment of real life eating difficulties in Parkinson’s disease patients by measuring plate to mouth movement elongation with inertial sensors

  1. N/A (i.e., Not Available) is used to indicate TN cannot be calculated using the adopted evaluation scheme47; this is depicted in Fig. 5. The total number of true bites in EaC is 1062 (sum of TP and FN). Given the confusion matrix, the performance metrics precision/recall/F1 are calculated to be 0.929/0.975/0.952.
