A feedback system for a children's helpline training-chatbot

De Kindertelefoon is a children's helpline aimed at providing (pre-)adolescents with a person to talk to for a variety of subjects such as bullying, sex, and abuse. These people who talk for De Kindertelefoon need proper training and guidance. Among the tools that De Kindertelefoon provides is the 5-phase model, a conversational model....

The Impact of Test Case Clustering on Comprehending Automatically Generated Test Suites

Software testing, a critical phase in the software development lifecycle, is often hindered by the time-intensive and costly manual creation of test cases. While automating test case generation could mitigate these challenges, its adoption in the industry has been limited due to difficulties in comprehending the generated test cases. To address...

Animating Still Images: Folding Texture Design and Synthesis

The phenomenon of one element moving and progressively overlaying another is common in nature, such as waves swashing and backwashing, or eyelids moving over eyeballs while blinking. Folding Texture, which was proposed by Thorben, can simulate this texture “folding” visual effect in real-time without changing geometry.<br/>However, to date, no...

User Interface Optimization for Quantified Self

Self-tracking has expanded exponentially in an era defined by the ubiquitous presence of wearable technologies and smart devices. From health and fitness to finances and productivity, these devices empower users to delve into their quantified self (QS) through an almost infinite amount of visualizations. However, a user has limited time to...

Using and Abusing Equivariance: Investigating Differences between Exact and Approximate Equivariance in Computer Vision

In this work we show how Group Equivariant Convolutional Neural Networks use subsampling to learn to break equivariance to their symmetries. We focus on the 2D roto-translation group and investigate the impact of broken equivariance on network performance. We show that changing the input dimension of a network by as little as a single pixel can...

Factors influencing students' perception of computer science

In our digital society, having computer science skills is becoming imperative, yet there is a shortage of computer science professionals and teachers. This shortage is linked to the perception people have of computer science and computer science professionals. This research paper answers two questions through a mixed-method study: to what extent...

Trust and Perceived Control in Burnout Support Chatbots

Increased levels of user control and feedback incorporation in learning systems is commonly cited as good AI development practice. However, the evidence as to the exact effect of perceived control over trust in these systems is mixed. This study investigates the relationship between different dimensions of trust and perceived control in...

Music Playlist Generation for Emotion Regulation: A Functional Component in the Individualized Music Intervention for Persons with Dementia

Dementia care is a growing problem, both due to a rising number of cases and due to a shortage in healthcare workers. Aside from cognitive symptoms persons with dementia (PwDs) often deal with psychological symptoms such as agitation. The individualized music intervention (IMI) by Linda Gerdner has been proposed to reduce these. This is the...

Weaponize personnel against social engineering attacks via gamified active inoculation

The number of cybercrime cases rises rapidly, and the type of crime takes more and more diverse forms. However, the protection against these risks lag behind and becomes quickly outdated. This thesis follows the Fake News Game example using active inoculation in the form of a game against social engineering risks. Inoculation draws the analogy...

EyeIDEA: Paving the Way Towards an Augmented Eye-Tracking IDE

Since their invention, the keyboard and mouse are the most used input devices that software developers use to interact with source code. However, these devices have their IDE interaction issues as developers need to spend a significant amount of time learning how to use them efficiently and effectively. To tackle some of these issues, we used an...

Visual Analysis for Narcolepsy

Narcolepsy is a chronic neurological condition that results from the dysregulation of the sleep-wake cycle occurring in an early stage, specifically in adolescence. Patients with narcolepsy experience excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis and disturbed nocturnal sleep and these symptoms together form...

Learning What to Attend to: Using bisimulation metrics to explore and improve upon what a deep reinforcement learning agent learns

We analyze the internal representations that deep Reinforcement Learning (RL) agents form of their environments and whether these representations correspond to what such agents should ideally learn. The purpose of this comparison is both a better understanding of why certain algorithms or network architectures perform better than others and the...

Modelling and Improving Social Housing Markets

Social housing corporations in the Netherlands have a limited ability to influence the social housing market through offering houses to households outside of the regular waiting-list system, but often do not use an algorithmic strategy for utilising this freedom well. There is thus an open question of whether there exist algorithmic approaches...

Generating Teacher Feedback through Parsons Problems

As computer science lies at the heart of almost all technological progress, widespread computer science education, and particularly programming education, is of great importance. In order to reach a large group of students, secondary schools can play an important role. However, students have difficulty learning programming concepts. Programming...
