Abstract

Predictive process monitoring in the context of adaptive case management is a growing area of research at the intersection of Predictive Analytics and Process Mining. In my masters thesis, I am trying to unify a novel approach in learning preparation through clustering with LSTM neural networks. The results will be compared to those of four papers.

Abstract

Acknowledged multicasts are a crucial to consistency mechanisms. Sequential propagation is used in practice, resulting in poor performance on larger multicore processors. The impact of tree-based multicast on latency and throughput is evaluated with user-space RCU benchmarks by extending the membarrier systemcall of the Linux kernel.

Abstract

Modern neuroimaging provides scientists and medical professionals with a wealth of rich, multi-faceted data – which unfortunately are still analysed with paradigms that have hardly changed in decades. This project proposes a fundamental change by using advances in deep neural networks to find complex, non-linear patterns in neurophysiological data.

Abstract

We are using neural networks for finding QRS complexes (representing heart beats) in electrocardiograms (ECGs). QRS detection is traditionally done by means of signal processing which performs poorly on low quality (e.g. noisy) data. We hypothesize that neural networks offer greater accuracy while being more robust to changes in signal quality.

Automated generation of test suites tackles the complexity of testing apps. The selection of the generation method is typically done in a trial-and-error fashion due to unknown characteristics of the apps. Analyzing the fitness landscapes of Google Play's top 1000 apps, we want to understand the characteristics and improve the generation method.

In this project, we study, model and predict live migration overhead using machine learning techniques. It is important to predict the live migration impact on the datacenter performance and to take the migration decision at the optimal times. This is to avoid conflict of interest between the application resources usage and live migration overhead.

We want to investigate the use of GPUs for enterprise relevant machine learning algorithms. In particular we aim to adapt an implementation of an algorithm for causal inference to target the GPU as an execution device. This shall reduce the execution time of the algorithm and in addition free CPU cycles to be used by other enterprise applications.
