Empirical Tensor Train Approximation in Optimal Control
Abstract: We display two approaches to solve finite horizon optimal control problems. First we solve the Bellman equation numerically by employing the Policy Iteration algorithm. Second, we introduce a semiglobal optimal control problem and use open loop methods on a feedback level. To overcome computational infeasability we use tensor trains and multi-polynomials, together with high-dimensional quadrature, e.g. Monte-Carlo. By controlling a destabilized version of viscous Burgers and a diffusion equation with unstable reaction term numerical evidence is given.

How to efficiently pre-process unstructured data for process mining?
Abstract: Process mining is a promising approach to find additional patterns in data and in that way to give new insights into the data. The challenge of process mining on unstructured data is to efficiently pre-process the data in a way that process mining can give additional insights. If the data is not clustered appropriately, the result might be distorted (i.e., there is a correlation between clustering and the discovered process model). This talk presents approaches for change point detection and encodings allowing to divide the pre-processed data representative for process mining.
