The model we propose tackles the problem of generating the data features constrained by the specific graph structure of each data point by splitting the task into two phases. In the first it models the distribution of features associated with the nodes of the given graph, in the second it complements the edge features conditionally on the node features. We follow the strategy of implicit distribution modelling via generative adversarial network (GAN) combined with permutation equivariant message passing architecture operating over the sets of nodes and edges. This enables generating the feature vectors of all the graph objects in one go (in 2 phases) as opposed to a much slower one-by-one generations of sequential models, prevents the need for expensive graph matching procedures usually needed for likelihood-based generative models, and uses efficiently the network capacity by being insensitive to the particular node ordering in the graph representation. To the best of our knowledge, this is the first method that models the feature distribution along the graph skeleton allowing for generations of annotated graphs with user specified structures. Our experiments demonstrate the ability of our model to learn complex structured distributions through quantitative evaluation over three annotated graph datasets.}, language = {en} } @inproceedings{AdemolaReichGregorova, author = {Ademola, Esther and Reich, Martin and Gregorov{\´a}, Magda}, title = {An Investigative Study Exploring Machine Learning Approaches for Optimizing Deep Brain Stimulation Programming}, series = {Modelling and Development of Intelligent Systems - 9th International Conference, MDIS 2024, Sibiu, Romania, October 17-19, 2024, Revised Selected Papers}, volume = {2486}, booktitle = {Modelling and Development of Intelligent Systems - 9th International Conference, MDIS 2024, Sibiu, Romania, October 17-19, 2024, Revised Selected Papers}, editor = {Simian, Dana and Florentina Stoica, Laura}, doi = {10.1007/978-3-031-87386-7_6}, pages = {75 -- 89}, language = {en} } @article{BenkertHerothHerrleretal., author = {Benkert, Marius and Heroth, Michael and Herrler, Rainer and Gregorov{\´a}, Magda and Schmid, Helmut C.}, title = {Variational autoencoder-based techniques for a streamlined cross-topology modeling and optimization workflow in electrical drives}, series = {Auton.

Thinking of textual web content, compression quickly comes to mind as a possibility to reduce traffic. The current HTTP/1.1 standard only provides gzip as an option for content encoding. HTTP/2.0 is under heavy development and numerous new algorithms have been established over the last few years. This paper analyzes HTTP traffic composition on a production server and concludes that about 50\% is compressible. It further examines the effectiveness of custom and existing algorithms with regards to compression ratio, speed, and energy consumption. Our results show that gzip is a sound choice for web traffic but alternatives like LZ4 are faster and provide competitive compression ratios.}, language = {en} } @article{WambachKnorr, author = {Wambach, Tim and Knorr, Konstantin}, title = {Technische Pr{\"u}fung der Datenschutzerkl{\"a}rungen auf deutschen Hochschulwebseiten}, series = {FHWS Science Journal}, volume = {3 (2015)}, journal = {FHWS Science Journal}, number = {2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:863-opus-3010}, pages = {44 -- 57}, abstract = {Alle deutschen Hochschulen pr{\"a}sentieren sich im Internet {\"u}ber eine Webseite.

This work presents different approaches of preprocessing and rendering light field videos made with a Lytro Illum, a plenoptic camera using microlenses. We compare three differently preprocessed light field videos and reveal the main issues for rendering on consumer hardware. Our results show, that one of the biggest obstacles lies in the transfer of data from light field video files to the main memory of the system. Therefore, the demosaiced and color corrected representation that balances preprocessing and resulting video file size is fastest in rendering light field video files. Rendering a short light field video directly from the main memory allows interaction like refocusing in real time and points out the need for future research on new codecs for light field videos based on non-raw light field images.}, language = {en} } @article{Reiss, author = {Reiss, Manuela}, title = {Dokumentationsmanagement als Erfolgsfaktor eines effektiven Informationssicherheitsmanagements}, series = {FHWS Science Journal}, volume = {3 (2015)}, journal = {FHWS Science Journal}, number = {2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:863-opus-3003}, pages = {34 -- 42}, abstract = {Ein integriertes Dokumentationsmanagement ist ein wichtiger Erfolgsfaktor f{\"u}r ein effektives Informationssicherheitsmanagement.

Our interaction approach is based on a robust and fast running 3D hand- and head-tracking provided by Microsoft's Kinect. We present a simple non-collision-based method for grabbing and manipulating objects within a 3D virtual environment. By tracking the head, the user is able to move within the environment and interact depending on his current position. The use of stereoscopic vision allows a natural and instinctive hand interaction with the augmented object.
