From: Workplace activity classification from shoe-based movement sensors
Performance of second random forest classifier in the lab calibration setting with sitting and standing combined to stationary as well as stair ascending and descending combined to stair walking. The numbers in the chart are row normalized, showing the distribution of the classification of the samples from each activity according to the test protocol. Y-axis shows the activity performed according to the test protocol. X-axis shows the predicted activity from the trained classification model
