Project A1 Data Mining for Ubiquitous System Software: Finding usage patterns in system log data of ubiquitous systems will be tackled in two ways. First, data are aggregated by streaming algorithms at the ubiquitous system, finding patterns or motifs that are well suited for further learning. Second, the log data are analysed by graphical models (e.g., CRF, SVMstruct), regarding special kernel functions. These algorithms are parallelized for CUDA implementation. Finally, distributed clustering algorithms are investigated in order to find groups of usage patterns.

Project A2 Algorithmic Aspects of Learning Methods in Embedded Systems: Algorithmic foundations of learning methods in resource-constrained systems are investigated with respect to memory models. In particular, clustering algorithms, graph algorithms, distributed algorithms, and data streaming algorithms are investigated with respect to energy consumption. Developing the theoretical basis for resource-aware learning is the focus of A2.
Project A3 Methods for the Efficient Resource Utilization in Machine Learning Algorithms: R programs are analyzed w.r.t. their resource consumption and a well-tailored compilation strategy will be developed. For diverse statistical learning algorithms the trade-off between quality of the learned model and recourse consumption will be determined. In particular, problems of model selection, feature selection will be investigated.

Project TB1 Resource-efficient and Distributed Platforms for Integrative Data Analysis: The analysis of spectroscopy data from a breath sensor for the timely disease diagnosis requires an online method for feature extraction, alignment methods, and prediction of spectra. High-throughput data analysis, bioinformatics, and online algorithms are the fields that contribute to developing smart wear including a breath sensor.

Project B2 Resource-optimizing time analysis of artifactious image sequences for the detection of nano objects: Plasmon assisted microscopy of nano objects (PAMONO) is a new sensor measuring extremely little objects. The PAMONO images are to be analysed in order to detect and classify viruses. The images are suffering from noise. Cleaning the data, comparing image analysis algorithms regarding their recognition capabilities and their respective resource consumptions are the tasks of data mining in this project.

Project C1 Feature Selection in High Dimensional Data for Risk Prognosis in Oncology: Ensemble methods are to be investigated, in how much they increase the stability of feature selection in high dimensional data where much less examples are given than features. Sets of exons (several exons make up for a gene) are to be clustered w.r.t. the oncology prognosis. Transfer learning will be evaluated concerning example sets stemming from different methods and collections of patients. Co-training will combine and fuse divers studies on exons or genes for neuroblastoma patients.

Project C2 Multi-level statistical analysis of high-frequency spatio-temporal process data: High-frequency high-dimensional process data are typically
analyzed in several steps. Interesting data need to be identified
and selected in real time for further analysis because of limited
storage capacities. By means of the challenging example of detection
and classification of astrophysical particles appearing as transient
patterns in spatio-temporal data, we want to construct robust
generalizable techniques for reduction, classification and modeling
of such data, as well as strategies for the suitable combination of
these analysis steps.
Project C3 Regression approaches for large-scale high-dimensional data: The scalability of modern regression approaches is often stretched to its limits by a large number of observations and/or variables. This aggravates their use in embedded systems. The goal of this project is therefore the development of highly efficient regression methods. Algorithms are to be developed that reduce the number of observations using, e.g., random linear projections and sampling (streaming algorithms), or the dimensionality of the underlying, possibly Bayesian, model classes imposing structural constraints, e.g., monotonicity.

Project A1 Data Mining for Ubiquitous System Software: Instrumenting the operating system of ubiquitous systems for data gathering is difficult, since logging the data must not disturb the regular use of the system. The instrumentation must be platform independent. New methods based on Dynamic Aspect C++ are to be developed and optimized regarding resource consumption. Applying learned models to the operating systems requires a generic framework so that efficiency is actually enhance by them.

Project A3 Methods for the Efficient Resource Utilization in Machine Learning Algorithms: This project builds a bridge between learning algorithms in terms of R programs and resource efficiency. Based on an internal representation of R, optimizations of the compiler are to be developed that take into account memory allocations. The optimized internal representation is then transformed until a stanrad compiler and C++ libraries produce resource-efficient code.

Project A4 Resource Efficient and Distributed Platforms for Integrative Aata Analysis: This project explores technical and conceptual foundations for
distributed execution platforms that are self-descriptive regarding their
provision and consumption of resources. In particular, the description of resources like memory, power consumption, bandwidth, or runtime constraints is of special interest. Due to the platform's ability to describe itself, applications have a valid basis for resource-aware decisions and hence are enabled to optimize their resource requests. The major challenge of this approach is to deal with the vast complexity of embedded platforms and dynamic interactions between the resource types envisaged.
Project B2 Resource-optimizing Time Analysis of Artifactious Image Sequences for the Detection of Nano Objects: The platform from project A4 is enhanced. Here, FPGA approaches and implementations for GPGPU are developed. In order to gain independence from various multiprocessor architectures, a high-level synthesis and multi-objective optimization of hardware-software partitionings are to be investigated.

Project B4 Analysis and Communication for Dynamic Traffic Prognosis: This project researches innovative, high precision and real time prognosis algorithms to predict object stream behaviour. The quality of the prognosis depends on the quantity, quality and reliability plus synchronicity of the available information on representative objects in the stream. In consideration of the avaiability of the multitude of sensor data sources as well as resource starved embedded systems, this sub-project also explores novel data aggregation, fusion and communication methods with respect to the requirements set by the prognosis, and evaluates the expected benefits.

Project A5 Exchange and Fusion of Information under Availability and Confidentiality Requirements in Multi-Agent Systems: Achieving both availability and confidentiality of information implies the development and employment of concepts and algorithms that handle conflicting security issues of actors and persons. This should be possible even in situations with limited technical infrastructure in terms of time, space, and communication. This project aims at extending data base techniques to multi-agent systems oriented towards the approach of J.Y. Halpern and K.R. OÕNeill (2005, 2008), in particular for the purpose of data mining in embedded systems.
