Ambient Intelligence and Machine Learning

Decanato - Facoltà di scienze informatiche

Data: 29 Settembre 2022 / 13:30 - 14:30

USI Campus EST, room D1.14, Sector D

Speaker: Hristijan Gjoreski

Abstract:
The recent technological advancements in sensor miniaturization allowed numerous applications in the areas of ambient intelligence, ubiquitous computing, mobile health etc. This talk will focus on few important machine-learning applications in with wearable devices such as smartphones, smartwatches, smart wristbands, etc. The first part of the talk will introduce the whole process of development of a machine learning pipeline for human activity recognition with wearable accelerometers. Numerous technical steps in the creation of the classification model will be discussed, such as: sensor data filtering, data segmentation, feature engineering, training a classification model and its evaluation. Additionally, some ideas and recent trends will be presented, including deep learning approaches, transfer learning, and unsupervised learning. The second part of the talk will focus on other ML applications in wearable computing such as: calorie expenditure estimation, fall detection, stress and arousal recognition. Each of these applications will be individually discussed and appropriate ML solutions will be presented.
