Titre : In‐Depth Learning of Raw Human Activity Data Auteurs : Hamdi Amroun, M’Hamed (Hamy) Temkit, Mehdi Ammi, Revue : Internet of Things Numéro : Issue 2 Volume : 1 Date : 2017/06/19 DOI : 10.21494/ISTE.OP.2017.0150 ISSN : 2514-8273 Résumé : This paper proposes to study the recognition of certain daily physical activities by using a network of smart objects. The approach consists in the classification of certain participants’ activities, the most common ones and those that are carried out with smart objects:Make a phone call (Call), open the door (Open), close the door (Close) and watch its smartwatch (Watch). The study exploits a network of commonly connected objects: a smart watch and a smartphone, transported by participants during an uncontrolled experiment. The sensors’ data of the two devices were classified by a deep neural network (DNN) algorithm without prior data pre-processing. We show that DNN provides better results than Decision Tree (DT) and Support Vector Machine (SVM) algorithms. The results also show that some participants’ activities were classified with an accuracy of more than 98%, on average. Éditeur : ISTE OpenScience
