Optimal Transport for Interactive Interpolation Problems in Computer Graphics
(2022-03-09)
Modern computer graphics require realistic surface materials and geometries for generating convincing imagery. Both types of data are inherently complex for most applications. To obtain them, measurement of real-world ...
Mining Frequent Itemsets from Transactional Data Streams with Probabilistic Error Bounds
(2020-05-27)
Frequent itemset mining is a classical data mining task with a broad range of applications, including fraud discovery and product recommendation. The enumeration of frequent itemsets has two main benefits for such applications: ......
Theoretical Analysis of Hierarchical Clustering and the Shadow Vertex Algorithm
(2020-05-05)
Agglomerative clustering (AC) is a very popular greedy method for computing hierarchical clusterings in practice, yet its theoretical properties have been studied relatively little. We consider AC with respect to the most ...
Federated Query Processing over Heterogeneous Data Sources in a Semantic Data Lake
(2020-05-05)
Data provides the basis for emerging scientific and interdisciplinary data-centric applications with the potential of improving the quality of life for citizens. Big Data plays an important role in promoting both manufacturing ...
Transient Non-Line-of-Sight Imaging
(2021-05-05)
Sight is perhaps the most important sense of the human species. But while it allows us to gain a near-instant understanding of our surrounding, it has a fundamental limitation: An object can be hidden from view if it is ......
Das Sehen ist die vielleicht wichtigste Sinneswahrnehmung des Menschen. Es erlaubt uns in Sekundenbruchteilen unsere Umgebung einschätzen zu können, hat dabei jedoch eine fundamentale Einschränkung: Ein Objekt kann nicht ......

Robot navigation in cluttered environments
(2022-01-11)
Service robots are designed for non-industrial use to help people at home and in public spaces. Today, service robots perform a variety of tasks that range from distributing medical supply to clean the floor. The wide range ...
Similarities and Representations of Graph Structures
(2021-06-01)
Graphs are a natural representation for diverse systems ranging from social networks to the Web and brain structure. Even when data is not interconnected explicitly, it is often convenient to convert it into a graph for ...
Recognizing and Anticipating Human Activities in Videos
(2022-04-04)
Analyzing human actions in videos has gained increased attention recently. Several approaches, for instance, have been proposed to classify and temporally segment actions in videos. Despite the success of these approaches, ...
Software Supply Chain Angriffe: Analyse und Erkennung
(2021-09-29)
Moderne Softwareentwicklung profitiert in vielen Hinsichten von der ausgiebigen Wiederverwendung externer Softwaremodule. Die Abhängigkeit von externen und somit schwer zu kontrollierenden Softwaremodulen – welche in ihrer ...
Mechanism-based Stratification of Alzheimer's and Parkinson's Disease using Artificial Intelligence
(2021-03-29)
The capacity to generate omics and clinical data in biomedical science is growing exponentially over the past decades. Additionally, recent advances in computational power and analyzing capabilities have resulted in ...
