QUACK: Quantum Aligned Centroid Kernel

1 code implementation1 May 2024 Kilian Tscharke, Sebastian Issel, Pascal Debus

As a small step in improving the potential applications of QKMs, we introduce QUACK, a quantum kernel algorithm whose time complexity scales linear with the number of samples during training, and independent of the number of training samples in the inference stage.

A Comparative Analysis of Adversarial Robustness for Quantum and Classical Machine Learning Models

no code implementations24 Apr 2024 Maximilian Wendlinger, Kilian Tscharke, Pascal Debus

While adversarial attacks successfully transfer across this boundary in both directions, we also show that regularization helps quantum networks to be more robust, which has direct impact on Lipschitz bounds and transfer attacks.

Protecting Publicly Available Data With Machine Learning Shortcuts

no code implementations30 Oct 2023 Nicolas M. Müller, Maximilian Burgert, Pascal Debus, Jennifer Williams, Philip Sperl, Konstantin Böttinger

Machine-learning (ML) shortcuts or spurious correlations are artifacts in datasets that lead to very good training and test performance but severely limit the model's generalization capability.

Semisupervised Anomaly Detection using Support Vector Regression with Quantum Kernel

no code implementations1 Aug 2023 Kilian Tscharke, Sebastian Issel, Pascal Debus

Kernel methods based on quantum kernel estimation have emerged as a promising approach to QML on NISQ devices, offering theoretical guarantees, versatility, and compatibility with NISQ constraints.

Deep Reinforcement Learning for Backup Strategies against Adversaries

no code implementations12 Feb 2021 Pascal Debus, Nicolas Müller, Konstantin Böttinger

In this setting, the usual round-robin scheme, which always replaces the oldest backup, is no longer optimal with respect to avoidable exposure.
