Performance metrics for activity recognition [PDF]
ACM Transactions on Intelligent Systems and Technology, 2011 In this article, we introduce and evaluate a comprehensive set of performance metrics and visualisations for continuous activity recognition (AR). We demonstrate how standard evaluation methods, often borrowed from related pattern recognition problems, fail to capture common artefacts found in continuous AR—specifically event fragmentation, event ...

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

Proceedings 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]
2017 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.
