Varga, Roland (author)Many recent robot learning problems, real and simulated, were addressed using deep reinforcement learning. The developed policies can deal with high-dimensional, continuous state and action spaces, and can also incorporate machine-generated or human demonstration data. A great number of them depend on state-action value estimates, especially the...master thesis 2023

Saccher, M. (author), Kawasaki, S. (author), Klootwijk, Johan (author), van Schaijk, Rob (author), Dekker, R. (author)Recently, the applications of ultrasound transducers expanded from high-end diagnostic tools to point of care diagnostic devices and wireless power receivers for implantable devices. These new applications additionally require that the transducer technology must comply to biocompatibility and manufacturing scalability. In this respect,...journal article 2023

Conde Santos Borba, P. (author), Sousa, Wilson C. (author), Shadman, Milad (author), Pfenninger, Stefan (author)During atypical droughts, power systems with a heavy reliance on hydropower risk increased greenhouse gas emissions if they are balanced with fossil-fired generation. This work investigates the role of offshore wind energy in reducing the vulnerability of power systems dependent on such hydrological patterns, thereby eliminating this emission...journal article 2023

Draws, T.A. (author), Natesan Ramamurthy, Karthikeyan (author), Baldini, Ioana (author), Dhurandhar, Amit (author), Padhi, Inkit (author), Timmermans, Benjamin (author), Tintarev, N. (author)One way to help users navigate debated topics online is to apply stance detection in web search. Automatically identifying whether search results are against, neutral, or in favor could facilitate diversification efforts and support interventions that aim to mitigate cognitive biases. To be truly useful in this context, however, stance...conference paper 2023

Liu, S. (author), Sinke, J. (author), Dransfeld, C.A. (author)The bias-extension test is one of the test methods to characterise the intra-ply shear behaviour of continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For the determination of the major mechanical properties of metals, often a uniaxial tensile test is used. Combination of these two methods for the...journal article 2023

(author)Adverse phenomena such as the search engine manipulation effect (SEME), where web search users change their attitude on a topic following whatever most highly-ranked search results promote, represent crucial challenges for research and industry. However, the current lack of automatic methods to comprehensively measure or increase viewpoint...conference paper 2023

(author)Aims: Implicit gender biases (IGBs) are unconscious evaluations about a person based on gender. IGBs of healthcare providers may affect medical decision making. This study investigated whether IGBs and genders of patients and general practitioners (GPs) influence diagnostics and treatment decisions in the context of diabetes type 2.

Paulus, D. (author), de Vries, G. (author), Janssen, M.F.W.H.A. (author), Van de Walle, Bartel (author)The complex and uncertain environment of the humanitarian response to crises can lead to data bias, which can affect decision-making. Evidence of data bias in crisis information management (CIM) remains scattered despite its potentially significant impact on crisis response. To understand what biases emerge in complex crises and how they affect...journal article 2023

Rieger, A. (author), Bredius, F. (author), Tintarev, N. (author), Pera, M.S. (author)We often use search engines when seeking information for opinion-forming and decision-making on debated topics. However, searching for resources on debated topics to gain well-rounded knowledge is cognitively demanding, leaving us vulnerable to cognitive biases, such as confirmation bias. This can impede well-informed decision-making, and on...conference paper 2023

Arzberger, Anne (author)Growing up, social constructs like roles, norms and values are being internalised and naturalised. Despite offering a sense of stability, such constructs also prohibit equality, justice and diversity, by pushing people into categories, roles and norms they do not represent. However, once internalised, social constructs fall under the surface of...master thesis 2022

Vlekke, Jimmy (author)Global warming causes coral bleaching which threatens the health and existence of coral reefs and therefore also the future of a lot of species, including human beings. Efforts to automate coral reef monitoring using annotated coral images to detect coral bleaching are hindered by the lack of a complete dataset that specifies the health and...master thesis 2022

Jimenez Lluva, Miriam (author)Today many products exclude users from different sociodemographic groups such as ethnicity and race. Examples of these in physical products are automatic soap dispensers and airport body scanners. The digital era has appeared and there are still digital products excluding users of different ethnicities and race, for example, dating apps and...master thesis 2022

Paulus, D. (author), de Vries, G. (author), Janssen, M.F.W.H.A. (author), Van de Walle, Bartel (author)A crisis requires the affected population, governments or non-profit organizations, as well as crisis experts, to make urgent and sometimes life-critical decisions. With the urgency and uncertainty they create, crises are particularly amenable to inducing cognitive biases that influence decisionmaking. However, there is limited empirical...journal article 2022

Zhang, Yixuan (author)One of the most important problems that needs tackling for wide deployment of Automatic Speech Recognition (ASR) is the bias in ASR, i.e., ASRs tend to generate more accurate predictions for certain speaker groups while making more errors on speech from others. In this thesis, we aim to reduce bias against non-native speakers of Dutch compared...master thesis 2022

Ahmed Adil el Tayeb Abdelnour, Ahmed (author)Regional climate model (RCMs) simulations are used in hydrological (climate-change) impact assessment studies. However, RCMs exhibit noticeable deviation from observation, and can show large variation in ensemble projections (biases). The objective of this study is twofold, first to assess the robustness of two high-skill bias-correction methods...master thesis 2022

Biedma Nuñez, Pablo (author)The increasing dangers of unfairness in machine learning (ML) are becoming a frequent subject of discussion, both, in academia and popular media. Recent literature focused on introducing and assessing algorithmic solutions to bias in ML. However, there is a disconnect between these solutions and practitioners' needs. By interviewing 30 ML...bachelor thesis 2022

Marinov, Alves (author)A problem prevalent in many modern-day Automatic Speech Recognition (ASR) systems is the presence of bias and its reduction. Bias can be observed when an ASR system performs worse on a subset of its speakers compared to the rest rather than having the same overall generalization for everyone. This can be seen by using Word Error Rates (WER) as a...bachelor thesis 2022

Mešić, Amar (author)Building Automatic Speech Recognizers (ASRs) has been a challenge in languages with insufficiently sized corpora or data sets. A further large issue in language corpora is biases against regionally accented speech and other speaker attributes. There are some techniques to improve ASR performance and reduce biases in these corpora, known as data...bachelor thesis 2022

Bălan, Dragos (author)There are many experiments conducted with Automatic Speech Recognition (ASR) systems, but many either focus on specific speaker categories or on a language in general. Therefore, bias could occur in such ASR systems towards different genders, age groups, or dialects. But, to analyze and reduce bias, the models require significant amounts of data...bachelor thesis 2022

van de Voort, Nick (author)Remotely Operated Vehicles (ROVs) are positioned relative to an underwater acoustic positioning system: Ultra-Short BaseLine (USBL). The accuracy is affected by refraction artifacts, caused by the variations of the sound velocity in the water column. Accurate positioning would require continuous measuring of the sound velocity profile (SVP)...master thesis 2022
