The main objective of this project is to develop design paradigms for learning algorithms in embedded systems. To this end, we will consider computational models that reflect important aspects of embedded systems, develop and analyse algorithms in these models and empirically evaluate their performance to make conclusions about their efficiency as well as the prediction power of the considered computational models. Then we would like to use the insights gained this way to derive general algorithmic design paradigms for embedded systems.

In this third phase of the project we will continue our study of the aspects energy consumption, communication and computation architecture, data streams and distributed systems. We know from the first two phases of the project as well as the findings of other projects (for example, A1, A6, B3, B4 and C4) that small summaries of the data, such as sketches or coresets, are a suitable design paradigm to obtain data-streaming and distributed algorithms. In the current phase we will continue in this direction and try to unite our findings in different computational models to design a single approach that fits different aspects of embedded systems. For this purpose, we want to continue to deepen our understanding of the individual approaches. Our focus will lie on energy consumption, which we will study both theoretically and empirically.
