Table 2.

Best leave-one-participant-out performance results for eating detection (sliding window = 50 seconds) when taking into account sensor data from the instrumented left hand, right hand, and both. Notice the gain in performance with the left-hand when either L1 or L2 normalization is applied to the data during pre-processing (also shown in Figure 3).

Preprocessing	Left Hand (F-score)	Right Hand (F-score)	Both Hands (F-score)
MinMax Scaling	48.9%	70.5%	69.1%
L1 Norm	70.7%	75.9%	74.9%
L2 Norm	71.8%	75.7%	76.3%
