Towards Transfer Learning for Large-Scale Image Classification Using Annealing-based Quantum Boltzmann Machines

no code implementations27 Nov 2023 Daniëlle Schuman, Leo Sünkel, Philipp Altmann, Jonas Stein, Christoph Roch, Thomas Gabor, Claudia Linnhoff-Popien

Quantum Transfer Learning (QTL) recently gained popularity as a hybrid quantum-classical approach for image classification tasks by efficiently combining the feature extraction capabilities of large Convolutional Neural Networks with the potential benefits of Quantum Machine Learning (QML).

SEQUENT: Towards Traceable Quantum Machine Learning using Sequential Quantum Enhanced Training

1 code implementation6 Jan 2023 Philipp Altmann, Leo Sünkel, Jonas Stein, Tobias Müller, Christoph Roch, Claudia Linnhoff-Popien

However, as high-dimensional real-world applications are not yet feasible to be solved using purely quantum hardware, hybrid methods using both classical and quantum machine learning paradigms have been proposed.

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.

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.

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.

Soccer Team Vectors

no code implementations30 Jul 2019 Robert Müller, Stefan Langer, Fabian Ritz, Christoph Roch, Steffen Illium, Claudia Linnhoff-Popien

In this work we present STEVE - Soccer TEam VEctors, a principled approach for learning real valued vectors for soccer teams where similar teams are close to each other in the resulting vector space.
