Appropriate context-dependent artificial trust in human-machine teamwork

As human-machine teams become a more common scenario, we need to ensure mutual trust between humans and machines. More important than having trust, we need all teammates to trust each other appropriately. This means that they should not overtrust or undertrust each other, avoiding risks and inefficiencies, respectively. We usually think of...

Think Too Fast Nor Too Slow: The Computational Trade-off Between Planning And Reinforcement Learning

Planning and reinforcement learning are two key approaches to sequential decision making. Multi-step approximate real-time dynamic programming, a recently successful algorithm class of which AlphaZero [Silver et al., 2018] is an example, combines both by nesting planning within a learning loop. However, the combination of planning and learning...

eHealth WhatsApp Group for Social Support: Preliminary Results

Within groups that are starting a healthy lifestyle intervention together, there is potential for social e-support, as an addition to individual coaching. However, the support technology should be low-tech, low-threshold and preferably already omnipresent. A WhatsApp group was chosen as support tool, given the large variety of groups normally...

Supporting request acceptance with use policies

This paper deals with the problem of automating the contribution of resources owned by people to do work for others, whilst providing a means for owners of resources to maintain autonomy over how, when and to whom their resources are used with the specification of resource use policies. We give representations of requests for resource usage as a...

User Validation of an Empathic Virtual Buddy against Cyberbullying

People are able to comfort others by talking about their problems. In our research, we are exploring whether computers can provide social support in a similar manner. Recently, we proposed a design for an empathic virtual buddy that supports victims of cyberbullying. To validate our approach in providing social support and to gather feedback...
