Project A1 develops data analysis methods for embedded systems. Learning methods are to consume resources minimally so that they can be executed by embedded systems. A1 contributes to these overall goals by developing the theoretical basis of machine learning under resource constraints. In particular, it investigates machine learning models that formalise implicit functional relations within the data. More precisely, a model, e.g., from the class of linear models, exponential families, decision trees, or convolutional networks, specifies the general formal basis of any machine learning method. It determines implicitly what is learned (e.g., classifier, probability density, clustering model), and from what it is learned (e.g., real-valued vectors, categorical data, count data). Instances of a particular model are assessed by a quality measure (e.g., root mean square error, F β -score, correct classification rate, or the likelihood). In A1, we extend this notion of quality by adding simplicity of model representation and simplicity of inference, where simplicity is relative to the underlying hardware architecture. Thus, the quality of a model may comprise its memory consumption, numerical precision, parameter integrality, or approximability. Since learning itself is often expressed by one or more optimisation problems, resource constraints are added to the quality measure via regularisation. Several algorithms exist that can find (approximate) solutions to optimisation problems. Finally, the algorithms are executed on a specific hardware platform. Each of these layers, i.e., platforms, algorithms, models, is studied in the research centre. Project A3 starts with the execution on a certain platform, project A2 moves on to algorithms, and project A1 investigates the models of learning.
There is a plentitude of heuristics that algorithmically save resources. However, heuristics most often come without guarantees. In the A1 project, we specify restrictions at the model level and analyse the impact of the restriction on the quality. Moreover, a model of learning with proven guarantees makes explicit the link from the restrictions of the model to those of constrained hardware. It is a long way to achieve such models with guarantees. For the class of learning within the exponential family, we succeeded in developing spatiotemporal random fields, integer Markov random fields, and a novel quadrature based on first principles, each focusing on specific constraints. Proven properties of the novel models conclude the basic research on exponential families. At the same time, applications in other projects have already shown their practical usefulness. For top-down decision trees, the journey has just begun, and first publications show the potential of linking tree models of learning to FPGAs.

Many approaches in the literature perform wear-leveling by making use of special hardware. Since most non-volatile memories only wear out from write accesses, the proposed approaches in the literature also usually try to spread write accesses widely over the entire memory space. Some non-volatile memories, however, also wear out from read accesses, because every read causes a consecutive write access. Software-based solutions only operate from the application or kernel level, where read and write accesses are realized with different instructions and semantics. Therefore different mechanisms are required to handle reads and writes on the software level. First, we design a method to approximate read and write accesses to the memory to allow aging aware coarse-grained wear-leveling in the absence of special hardware, providing the age information. Second, we provide specific solutions to resolve access hot-spots within the compiled program code (text segment) and on the application stack. In our evaluation, we estimate the cell age by counting the total amount of accesses per cell. The results show that employing all our methods improves the memory lifetime by up to a factor of 955x.} }')"> |
