-=====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=====
 +== Doctoral Candidate / Early Stage Researcher position == 
 +As a research associate at the Institute for Artificial Intelligence, you will develop systems for automated knowledge representation and knowledge acquisition, which combine the human ability of understanding language, perceiving objects and learning from experience. In particular, intelligent robots are to be endowed with the capability of autonomously acquire knowledge in order to robustly act in human environments and competently and successfully achieve everyday human-scale tasks.  
  
 +In particular, your challenges comprise the following:
 +  * the development and implementation of probabilistic models and algorithms for learning and reasoning in complex scenarios of intelligent service robots, 
 +  * the creation and maintenance of software documentation as well as the presentation of research results at top-tier international conferences, 
 +  * self-organized and ambitious work both individually and in a team of researchers, 
 +  * the authoring of research grant proposals.  
  
-== GPU-based Parallelization of Numerical Optimization Techniques (BA/MA/HiWi)==+Prerequisites:  
 +  * Successfully completed Master's degree (or equivalent) in Computer Science with a major in Artificial Intelligence/Machine Learning,  
 +  * very good skills in Machine Learning and Data Mining; esp. experience with probabilistic graphical models (Bayesian networks/Markov random fields/Markov logic networks) and related formalisms,  
 +  * very good programming skills in the Python/Cython/C/C++ programming languages and respective libraries for scientific computing (numpy/scipy/sympy),  
 +  * experience in natural-language understanding and semantic modeling helpful.
  
-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.+Besides the willingness and ability to quickly dive into new and complex research scenarios and topics, we expect organizational skills, the ability to work in a team and high commitment and dedication to you research. Very good skills of the English language is required.
  
-Requirements: +Research associate

 +== Lisp / CRAM support assistant (HiWi) ==
  
-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.+Technical support for the group for Lisp and the CRAM framework. \\ 
 +8+ hours per week for up to 1 year (paid).
  
 Requirements: Requirements:
-  * Experience in Machine Learning. +  * Good programming skills in Common Lisp 
-  * Experience with statistical relational learning (e.g. MLNs) is helpful. +  * Basic ROS knowledge
-  * Good programming skills in Python.+
  
-Contact: [[team:daniel_nyga|Daniel Nyga]]+The student will be introduced to the CRAM framework at the beginning of the job, which is a robot programming framework written in Lisp. The student will then be responsible for assisting not familiar with the framework people, explaining them the parts they don't understand and pointing them to the relevant documentation sources.

-In the context of the European research project RoboHow.Cog [1,2] we +In the scope of the CRC Farbige Zustände we use machine-learning techniques and novel high-troughput methods to find new materials. To present the project to the scientific community as well as to the non-scientific audience, we want to visualize its ideas and concepts in terms of interactive web applications. Your task would be to design and develop visualization tools that allow the interaction with the data of the project. You will work with Javascript/AngularJS/NodeJS and MongoDB, so it would be helpful if you already have experience in those fields. Creativity in developing new visualizations is demanded just as much as good programming skills.

- {{ :research:fluid.png?200|}}  
  
-[[http://gazebosim.org/|Gazebo]] currently only supports rigid body physics engines (ODE, Bullet etc.), however in some cases fluids are preferred in order to simulate as realistically as possible the given environment.+== Realistic Grasping using Unreal Engine (BA/MA/HiWi) ==
