Exploring Training Pair-Generation Strategies for Deep Metric Learning for Floor Plan Retrieval

Existing content-based image retrieval models work well for natural photos, but not for images of architectural floor plans. <br/>Previous work on floor plan retrieval has focused on graph-based methods, rather than image-based floor plans.<br/>Training a CNN-based representation learning framework on segmented floor plan images with standard...

Exploring Children’s Choices in an Educational Game on Neurodiversity: Reveiling Underlying Values through Robot’s Socratic Questioning

In the Netherlands, there is a shortage of primary school teachers, due to this shortage, teachers often do not have a lot of one-on-one time with the students. A social robot could be the solution to creating more one-on-“one” time with the students. In addition to relieving some workload for the teachers, a social robot...

Understanding the Role of Explanation Modality in AI-assisted decision-making

Advances in artificial intelligence and machine learning have led to a steep rise in the adoption of AI to augment or support human decision-making across domains.<br/>There has been an increasing body of work addressing the benefits of model interpretability and explanations to help end-users or other stakeholders decipher the inner workings of...

VisuaLayered: Combined Visual Analysis of MA-XRF and RIS Data

In this work, we present VisuaLayered, the implementation of a combined analysis workflow for pigment identification. VisuaLayered is an integrated, interactive system that focuses on the combined visual analysis of Macro X-Ray Fluorescence (MA-XRF) and Reflectance Imaging Spectroscopy (RIS) data.<br/><br/>Analysing paintings for pigment...

Value-Sensitive Rejection of Machine Learning Predictions for Hate Speech Detection

Hate speech detection on social media platforms remains a challenging task. Manual moderation by humans is the most reliable but infeasible, and machine learning models for detecting hate speech are scalable but unreliable as they often perform poorly on unseen data. Therefore, human-AI collaborative systems, in which we combine the strengths of...

Interaction Design Patterns for Social Robot Assistance of Moral Decisions in Healthcare: Confrontation with Resuscitation Dilemmas

The implementation of social robots in the healthcare industry is becoming substantial as a consequence of the scarcity of healthcare professionals, rising costs of healthcare and an increase in the number of vulnerable populations. Social robots will be deployed, in increasing numbers, in assisting health care professionals during the provision...

Automatic multimodal detection of team cohesion in meetings

In this thesis the automatic multimodal detection of social and task cohesion in meetings is studied. The presence of social and task cohesion has positive benefits on employee well-being, creativity and productiveness, and can therefore be used to assess meeting quality. Conversational partners imitate each other's body language and speech...
