Analysis of Students' Programming Knowledge and Error Development
(2022-02-01)Learning to program is a hard task since it involves different types of specialized knowledge. You do not only need knowledge about the programming language and its concepts, but also knowledge from the problem domain and ... -
Variational regularization theory for sparsity promoting wavelet regularization
(2022-01-31)In many scientific and industrial applications, the quantity of interest is not what is directly observed, but is instead a parameter which has a causal effect on experimental measurements. To obtain the desired unknown ... -
Automotive Target Models for Point Cloud Sensors
(2022-01-28)One of the major challenges to enable automated driving is the perception of other road users in the host vehicle’s vicinity. Various automotive sensors that provide detailed information about other traffic participants ... -
Ontology-based transformation of natural language queries into SPARQL queries by evolutionary algorithms
(2022-01-21)In this thesis an ontology-driven evolutionary learning system for natural language querying of RDF graphs is presented. The learning system itself does not answer the query, but generates a SPARQL query against the ... -
