-== GPU-based Parallelization of Numerical Optimization Techniques (BA/MA/HiWi)==+=====Theses and Student 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.
  
-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.+<html><!-- 
 +== Lisp / CRAM support assistant (HiWi) ==
  
-Requirements: +Technical support for the group for Lisp and the CRAM framework. \\ 
-  * Skills in numerical optimization algorithms +8+ hours per week for up to 1 year (paid).

-Contact: [[team:daniel_nyga|Daniel Nyga]] +
- +
-== Online Learning of Markov Logic Networks for Natural-Language Understanding (MA)== +
- +
-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.+
  
 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.

-We are currently investigating a new set of sensors (RGB-D-T), which is a combination of a kinect with a thermal image camera. Within this project we want to enhance the Depth-Adaptive Superpixels (DASP) to make use of the thermal sensor data. Depth-Adaptive Superpixels oversegment an image taking into account the depth value of each pixel. {{ :research:dt_dasp.png?200|}}

-Since the current implementation of DASP is not very performant for high resolution images, there are several possibilities options for doing a project in this field like reimplementing DASP using the CUDA, investigating how thermal data can be integrated, ...
