qgym: A Gym for Training and Benchmarking RL-Based Quantum Compilation

1 code implementation1 Aug 2023 Stan van der Linde, Willem de Kok, Tariq Bontekoe, Sebastian Feld

The goal of qgym is to connect the research fields of Artificial Intelligence (AI) with quantum compilation by abstracting parts of the process that are irrelevant to either domain.

Black Box Optimization Using QUBO and the Cross Entropy Method

1 code implementation24 Jun 2022 Jonas Nüßlein, Christoph Roch, Thomas Gabor, Jonas Stein, Claudia Linnhoff-Popien, Sebastian Feld

A common approach to realising BBO is to learn a surrogate model which approximates the target black-box function which can then be solved via white-box optimization methods.

Accelerating Evolutionary Construction Tree Extraction via Graph Partitioning

no code implementations9 Aug 2020 Markus Friedrich, Sebastian Feld, Thomy Phan, Pierre-Alain Fayolle

Extracting a Construction Tree from potentially noisy point clouds is an important aspect of Reverse Engineering tasks in Computer Aided Design.

A Flexible Pipeline for the Optimization of CSG Trees

no code implementations9 Aug 2020 Markus Friedrich, Christoph Roch, Sebastian Feld, Carsten Hahn, Pierre-Alain Fayolle

CSG trees are an intuitive, yet powerful technique for the representation of geometry using a combination of Boolean set-operations and geometric primitives.

Insights on Training Neural Networks for QUBO Tasks

no code implementations29 Apr 2020 Thomas Gabor, Sebastian Feld, Hila Safi, Thomy Phan, Claudia Linnhoff-Popien

Current hardware limitations restrict the potential when solving quadratic unconstrained binary optimization (QUBO) problems via the quantum approximate optimization algorithm (QAOA) or quantum annealing (QA).

Trajectory annotation using sequences of spatial perception

no code implementations11 Apr 2020 Sebastian Feld, Steffen Illium, Andreas Sedlmeier, Lenz Belzner

In the near future, more and more machines will perform tasks in the vicinity of human spaces or support them directly in their spatially bound activities.

Bayesian Surprise in Indoor Environments

no code implementations11 Apr 2020 Sebastian Feld, Andreas Sedlmeier, Markus Friedrich, Jan Franz, Lenz Belzner

Agents of LBS, such as mobile robots or non-player characters in computer games, may use the context surprise to focus more on important regions of a map for a better use or understanding of the floor plan.

Optimizing Geometry Compression using Quantum Annealing

no code implementations30 Mar 2020 Sebastian Feld, Markus Friedrich, Claudia Linnhoff-Popien

The compression of geometry data is an important aspect of bandwidth-efficient data transfer for distributed 3d computer vision applications.

Cross Entropy Hyperparameter Optimization for Constrained Problem Hamiltonians Applied to QAOA

2 code implementations11 Mar 2020 Christoph Roch, Alexander Impertro, Thomy Phan, Thomas Gabor, Sebastian Feld, Claudia Linnhoff-Popien

Such algorithms are usually implemented in a variational form, combining a classical optimization method with a quantum machine to find good solutions to an optimization problem.

Distributed Policy Iteration for Scalable Approximation of Cooperative Multi-Agent Policies

no code implementations25 Jan 2019 Thomy Phan, Kyrill Schmid, Lenz Belzner, Thomas Gabor, Sebastian Feld, Claudia Linnhoff-Popien

We experimentally evaluate STEP in two challenging and stochastic domains with large state and joint action spaces and show that STEP is able to learn stronger policies than standard multi-agent reinforcement learning algorithms, when combining multi-agent open-loop planning with centralized function approximation.

Segmented and Directional Impact Detection for Parked Vehicles using Mobile Devices

no code implementations16 Mar 2017 Andre Ebert, Sebastian Feld, Florian Dorfmeister

The system is capable of detecting the impact segment and the point of time of an impact event on a vehicle's surface, as well as its direction of origin.
