Optimizing Sensor Position with Virtual Sensors in Human Activity Recognition System Design

open access: yesSensors, 2021
Human activity recognition (HAR) systems combined with machine learning normally serve users based on a fixed sensor position interface. Variations in the installing position will alter the performance of the recognition and will require a new training ...

Analyzing Sensor-Based Individual and Population Behavior Patterns via Inverse Reinforcement Learning

open access: yesSensors, 2020
Digital markers of behavior can be continuously created, in everyday settings, using time series data collected by ambient sensors. The goal of this work was to perform individual- and population-level behavior analysis from such time series sensor data.

A Hierarchical Approach to Activity Recognition and Fall Detection Using Wavelets and Adaptive Pooling

open access: yesSensors, 2021
Human activity recognition has been a key study topic in the development of cyber physical systems and assisted living applications. In particular, inertial sensor based systems have become increasingly popular because they do not restrict users ...

Active Goal Recognition

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2020
The objective of goal recognition is to infer a goal that accounts for the observed behavior of an actor. In this work, we introduce and formalize the notion of active goal recognition in which we endow the observer with agency to sense, reason, and act in the world with a view to enhancing and possibly expediting goal recognition, and/or to ...

An activity description language for activity recognition [PDF]

open access: yes2017 International Conference on Internet of Things, Embedded Systems and Communications (IINTEC), 2017
Activity recognition aims at recognizing and understanding the movements, actions, and objectives of mobile objects. These objects can be humans, animals, or simple artefacts. Many important and critical applications such as surveillance or health care require some form of (human) activity recognition.
