Context-Adaptive Reinforcement Learning using Unsupervised Learning of Context Variables

Hamid Eghbal-zadeh, Florian Henkel, Gerhard Widmer
2020 NIPS Workshop on Pre-registration in Machine Learning  
In this paper, we introduce Context-Adaptive Reinforcement Learning Agent (CARLA), that is capable of learning context variables in an unsupervised manner, and can adapt the policy to the current context  ...  For example, when a new user interacts with a system, the system has to adapt to the needs of the user, which might differ based on the user's characteristics that are often not observable.  ...  We also gratefully acknowledge the support of NVIDIA Corporation with the donation of a Titan X GPU used for this research.  ...

Towards Activity Context using Software Sensors

Kamran Taj Pathan, Stephan Reiff-Marganiec
2009 Electronic Proceedings in Theoretical Computer Science  
Traditionally any context sensing was conducted with hardware sensors. However, software can also play the same role and in some situations will be more useful to sense the activity of the user.  ...  Context-aware computing promises to capture the user's needs and hence the requirements they have on systems.  ...  An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves.  ...
