Informed sampling-based trajectory planner for automated driving in dynamic urban environments

Smit, R. (author), van der Ploeg, C. (author), Teerhuis, A. (author), Silvas, E. (author)

The urban environment is amongst the most difficult domains for autonomous vehicles. The vehicle must be able to plan a safe route on challenging road layouts, in the presence of various dynamic traffic participants such as vehicles, cyclists and pedestrians and in various environmental conditions. The challenge remains to have motion planners...

A knowledge base for robots to model the real-world as a hypergraph

Sijs, J. (author), Fletcher, J. (author)

Robotic systems operating in the real world would benefit from a clear semantic model to understand the real world. Such semantics are typically captured in a knowledge structure. The speed at which robots need to update their real-world knowledge (because of new sensory observations) prevented the use of complex knowledge structures, due to...

The semantic snake charmer search engine: A tool to facilitate data science in high-tech industry domains

Grappiolo, C. (author), van Gerwen, M.J.A.M. (author), Verhoosel, J.P.C. (author), Somers, L. (author)

The booming popularity of data science is also affecting high-tech industries. However, since these usually have different core competencies - building cyber-physical systems rather than e.g. machine learning or data mining algorithms - delving into data science by domain experts such as system engineers or architects might be more cumbersome...

(author)

Intelligent robotic autonomous systems (unmanned aerial/ground/surface/underwater vehicles) are attractive for military application to relieve humans from tedious or dangerous tasks. These systems require awareness of the environment and their own performance to reach a mission goal. This awareness enables them to adapt their operations to...

ICM: An Intuitive Model Independent and Accurate Certainty Measure for Machine Learning

van der Waa, J. (author), van Diggelen, J. (author), Neerincx, M. (author), Raaijmakers, S. (author)

End-users of machine learning-based systems benefit from measures that quantify the trustworthiness of the underlying models. Measures like accuracy provide for a general sense of model performance, but offer no detailed information on specific model outputs. Probabilistic outputs, on the other hand, express such details, but they are not...

Driver readiness model for regulating the transfer from automation to human control

Mioch, T. (author), Kroon, L. (author), Neerincx, M.A. (author)

In the collaborative driving scenario of truck platooning, the first car is driven by its chauffeur and the next cars follow automatically via a so-called 'virtual tow-bar'. The chauffeurs of the following cars do not drive 'in the towbar mode', but need to be able to take back control in foreseen and unforeseen conditions. It is crucial that...

Semantic reasoning in zero example video event retrieval

de Boer, M.H.T. (author), Lu, Y.J. (author), Zhang, H. (author), Schutte, K. (author), Ngo, C.W. (author), Kraaij, W. (author)

Searching in digital video data for high-level events, such as a parade or a car accident, is challenging when the query is textual and lacks visual example images or videos. Current research in deep neural networks is highly beneficial for the retrieval of high-level events using visual examples, but without examples it is still hard to (1)...

Knowledge based query expansion in complex multimedia event detection

de Boer, M. (author), Schutte, K. (author), Kraaij, W. (author)

A common approach in content based video information retrieval is to perform automatic shot annotation with semantic labels using pre-trained classifiers. The visual vocabulary of state-of-the-art automatic annotation systems is limited to a few thousand concepts, which creates a semantic gap between the semantic labels and the natural language...

Designing a personal music assistant that enhances the social, cognitive, and affective experiences of people with dementia

Peeters, M.M.M. (author), Harbers, M. (author), Neerincx, M.A. (author)

Research shows that music with a strong personal meaning can enhance the social, cognitive, and affective experiences of both people with dementia (PwD) and their social environment. We applied a human-centred design method, called situated Cognitive Engineering, to develop the conceptual design and design rationale of the Music ePartner. The...

Water resources management issues tend to affect a variety of uses and users. Therefore, they often exhibit complex and unstructured problems. The complex, unstructured nature of these problems originates from uncertain knowledge and from the existence of divergent perceptions among various actors. Consequently, dealing with these problems is...

Controlling the power output of a nuclear reactor with fuzzy logic

Ruan, D. (author), van der Wal, A.J. (author), TNO Fysisch en Elektronisch Laboratorium (author)

The application of fuzzy logic control (FLC) in the domain of nuclear industry presents a tremendous challenge. The main reason for this is the public awareness of the risks of nuclear reactors and the very strict safety regulations in force for nuclear power plants. The very same regulations prevent a researcher from quickly introducing novel...
