Wearable Computing: Classification of Body Postures and Movements (PUC-Rio)
Donated on 4/8/2013
A dataset with 5 classes (sitting-down, standing-up, standing, walking, and sitting) collected on 8 hours of activities of 4 healthy subjects. We also established a baseline performance index.

Dataset Information
Additional Information
IMPORTANT: we have lower performance on 'leave-one-subject-out' tests. The performance baseline index we established is for 10-fold cross-validation tests. Therefore, there's much more space for optimization in subject independent tests. If you need more information, please send us an e-mail. Licensing: You are free to use this dataset for any purpose.
