We devise a hierarchical decision-making architecture for portfolio optimization on multiple markets. At the highest level Deep Reinforcement Learning (DRL) agent selects among number of discrete actions, representing low-level agents. For agents, we use set Hierarchical Risk Parity (HRP) and Equal Contribution (HERC) models with different hyperparameters, which all run in parallel, off-market ...

In structural engineering, active structures that combine the principles of lightweight construction with bending elastic component behavior are increasingly being investigated. For realization a prototype an hybrid roof structure at laboratory Hybrid Structures BTU Cottbus-Senftenberg, preliminary investigations on case study conducted in framework this publication order to improve design proc...

land cover information is one of the most important prerequisite in urban management system. in this way remote sensing, as the most economic technology, is mainly used to produce land cover maps. considering the complicated and dense urban areas in third world countries, object based approaches are suggested as an effective image processing technique. the purpose of this paper are the introduc...

Decision making and technical decision analysis demand computer-aided techniques and therefore more and more support by formal techniques. In recent years fuzzy decision analysis and related techniques gained importance as an efficient method for planning and optimization applications in fields like production planning, financial and economical modeling and forecasting or classification. It is ...

We study hierarchical clusterings of metric spaces that change over time. This is a natural geometric primitive for the analysis of dynamic data sets. Specifically, we introduce and study the problem of finding a temporally coherent sequence of hierarchical clusterings from a sequence of unlabeled point sets. We encode the clustering objective by embedding each point set into an ultrametric spa...

This paper presents a new approach to hierarchical high-level synthesis with respect to internal register-transfer structures of complex components. Entire subdesigns can efficiently be used as complex components at a higher hierarchical level of the design. After synthesis, the calculated schedule of each subdesign is added to its register-transfer component model. This enables the sharing of ...
