Your Job:

Reinforcement Learning (RL) is a versatile and powerful tool for control, but often data-inefficient, requiring numerous updates and non-local information such as replay buffers and batch-based processing. This project will investigate event-driven learning approaches in the context of RL in an event-triggered fashion. Data efficiency will be improved by using meta-learning and pre-training that facilitate few-shot adaptations. The research will show how the complementarity of event-triggered learning and meta-learning can drastically increase RL efficiency at test time.
The co-design of algorithms and digital neuromorphic hardware is an additional avenue for enhancing the efficiency of the methods. In this context the research will explore digital, event-based implementations of the event-based RL learning rule. Benchmarking criteria include accuracy, latency, data efficiency, and energy consumption to reach a learned solution on small robotic control tasks. Your tasks in detail:

• Develop an event-driven RL algorithm that sparsely updates network state and parameters that will significantly improve energy to-solution efficiency compared to conventional digital accelerators when applied to control problems or tiny RL scenarios.
  
• Explore digital hardware realizations of the proposed RL algorithms within existing spiking neural network chip designs.
  
• Quantitative comparisons with different hardware backends. Design conventional (GPU-based) deep neural networks for comparison.
  
• Publish research articles, regular participation in top international conferences to present your work.
  
• Complete two 6-month internships at TU Delft (Prof. Charlotte Frenkel) and at Mercedes-Benz, Böblingen.
  
• Participate in yearly retreats organized by the doctoral network participants
  
• Support the dissemination of software tools and concepts.
  
• Supervise student projects and BSc/MSc theses.

Your Profile:

• Master’s degree in physics, electrical/electronic engineering, computer science, mathematics, or a related field.
  
• Strong coding skills for programming neural networks, machine learning and machine learning software frameworks (e.g. PyTorch or Jax) is a must.
  
• The ability for creative and analytical thinking across discipline boundaries and abstraction levels is a must.
  
• Knowledge in integrated circuit design, testing and simulation using Cadence is a plus.
  
• Knowledge of digital neuromorphic hardware and sensors is a plus.
  
• Ability for collaborative work, interdisciplinary and cross-topical thinking.
  
• Very good communication skills in English, both spoken and written. PGI-15 offers an English speaking environment, therefore German language skills are not required.
