Table 4.

Comparison of performance (F1-score) of various sensor combinations for eating episode detection. The proximity sensor is used for segmenting the chewing sequences, and various sensor combinations subsequently detect the eating episodes. One-way repeated measures ANOVA determined that the mean F1-score differed significantly between the four sensor combinations.

Sensor(s) used Exploratory Study Free-Living Study
Proximity only (ref) 73.4% 66.4%
Proximity + IMU* 81.5% 78.7%
Proximity + ambient light 72.7% 70.3%
All Sensors* 81.6% 77.1%
