-=====Theses and Jobs===== 
-If you are looking for a bachelor/master thesis or a job as a student research assistant, you may find some interesting opportunities on this page. 
  
 +=====Open researcher positions=====
  
 +====Digital Twin Knowledge Base for submarine robot inspection/manipulation====
 +The Institute for Artificial Intelligence (IAI) investigates methods for cognition-enabled robot control. The research is at the intersection of robotics and Artificial Intelligence and includes methods for intelligent perception, dexterous object manipulation, plan-based robot control, and knowledge representation for robots. 
  
-== GPU-based Parallelization of Numerical Optimization Techniques (BA/MA/HiWi)==+As a researcher of the IAI, you actively research by applying and extending the elaborated methods and tools of the IAI (e.g., CRAM, KnowRoB, and openEASE) to the uncertainties of limited resources, computation, and sensor data of submarine robots. You develop a Digital Twin that simulates harsh continuously evolving environments and service tasks on real robots. You design a detailed representation of an environment to be inspected, including data coming from past inspections, both similar and different (e.g., transfer learning from an inspection of the interior of an installation). Your research will be especially the environment representation, semantic annotation, and sensor data fusion deal with noisy data and unreliable information in dynamic environments. You work with IAI researchers and engineers of the ROSEN Group, implementing a service for underwater pipeline inspection and maintenance.
  
-In the field of Machine Learning, numerical optimization techniques play a focal role. However, as models grow larger, traditional implementations on single-core CPUs suffer from sequential execution causing a severe slow-down. In this thesis, state-of-the-art GPU frameworks (e.g. CUDA) are to be investigated in order implement numerical optimizers that substantially profit from parallel execution.+**Prerequisites:** You have a strong background in some of the following fields: 
 +  * Digital Twins  
 +  * Knowledge Representation 
 +  * Data structures 
 +  * Data Stream Representation. 
  
-Requirements: +**Hiring institution:** University of Bremen
-  * Skills in numerical optimization algorithms +
-  * Good programming skills in Python and C/C+++
  
-Contact: [[team:daniel_nyga|Daniel Nyga]]+**PhD Enrollment:** PhD position in the Institute for Artificial Intelligence at University of Bremen. The project involves collaboration with ROSEN in Bremen and UiO in Oslo. 
  
-== Online Learning of Markov Logic Networks for Natural-Language Understanding (MA)==+The PhD examination acceptance requires a “Certificate of Equivalence for Foreign Vocational Qualifications”. More information available at [[https://www.kmk.org/zab/central-office-for-foreign-education/certificate-of-equivalence.html]] and [[https://www.uni-bremen.de/fileadmin/user_upload/sites/international/Studieren_in_Bremen/AnerkennungPromotion.pdf]] . Obtaining such a certificate is not necessary for the job application, but it is required later in the recruitment process.
  
-Markov Logic Networks (MLNs) combine the expressive power of first-order logic and probabilistic graphical models. In the past, they have been successfully applied to the problem of semantically interpreting and completing natural-language instructions from the web. State-of-the-art learning techniques mostly operate in batch mode, i.e. all training instances need to be known in the beginning of the learning process. In context of this thesis, online learning methods for MLNs are to be investigated, which allow incremental learning, when new examples come in one-by-one.+**Duration of the project:** 36 months 
 + 
 +**Main Academic Supervisor:** Prof. Michael Beetz, contact: beetz@cs.uni-bremen.de 
 + 
 +**Co-supervisors:** prof. Einar Broch Johnsen (UiO, Norway), dr. Peter Kampmann (ROSEN, Germany)
