Physics-Informed Bayesian Optimization of Variational Quantum Circuits

1 code implementation NeurIPS 2023 Kim A. Nicoli, Christopher J. Anders, Lena Funcke, Tobias Hartung, Karl Jansen, Stefan Kühn, Klaus-Robert Müller, Paolo Stornati, Pan Kessel, Shinichi Nakajima

In this paper, we propose a novel and powerful method to harness Bayesian optimization for Variational Quantum Eigensolvers (VQEs) -- a hybrid quantum-classical protocol used to approximate the ground state of a quantum Hamiltonian.

Towards Fixing Clever-Hans Predictors with Counterfactual Knowledge Distillation

no code implementations2 Oct 2023 Sidney Bender, Christopher J. Anders, Pattarawatt Chormai, Heike Marxfeld, Jan Herrmann, Grégoire Montavon

This paper introduces a novel technique called counterfactual knowledge distillation (CFKD) to detect and remove reliance on confounders in deep learning models with the help of human expert feedback.

From Hope to Safety: Unlearning Biases of Deep Models via Gradient Penalization in Latent Space

1 code implementation18 Aug 2023 Maximilian Dreyer, Frederik Pahde, Christopher J. Anders, Wojciech Samek, Sebastian Lapuschkin

Deep Neural Networks are prone to learning spurious correlations embedded in the training data, leading to potentially biased predictions.

Detecting and Mitigating Mode-Collapse for Flow-based Sampling of Lattice Field Theories

no code implementations27 Feb 2023 Kim A. Nicoli, Christopher J. Anders, Tobias Hartung, Karl Jansen, Pan Kessel, Shinichi Nakajima

In this work, we first point out that the tunneling problem is also present for normalizing flows but is shifted from the sampling to the training phase of the algorithm.

Navigating Neural Space: Revisiting Concept Activation Vectors to Overcome Directional Divergence

no code implementations7 Feb 2022 Frederik Pahde, Maximilian Dreyer, Leander Weber, Moritz Weckbecker, Christopher J. Anders, Thomas Wiegand, Wojciech Samek, Sebastian Lapuschkin

With a growing interest in understanding neural network prediction strategies, Concept Activation Vectors (CAVs) have emerged as a popular tool for modeling human-understandable concepts in the latent space.

Towards Robust Explanations for Deep Neural Networks

no code implementations18 Dec 2020 Ann-Kathrin Dombrowski, Christopher J. Anders, Klaus-Robert Müller, Pan Kessel

Explanation methods shed light on the decision process of black-box classifiers such as deep neural networks.

Estimation of Thermodynamic Observables in Lattice Field Theories with Deep Generative Models

no code implementations14 Jul 2020 Kim A. Nicoli, Christopher J. Anders, Lena Funcke, Tobias Hartung, Karl Jansen, Pan Kessel, Shinichi Nakajima, Paolo Stornati

In this work, we demonstrate that applying deep generative machine learning models for lattice field theory is a promising route for solving problems where Markov Chain Monte Carlo (MCMC) methods are problematic.

Finding and Removing Clever Hans: Using Explanation Methods to Debug and Improve Deep Models

2 code implementations22 Dec 2019 Christopher J. Anders, Leander Weber, David Neumann, Wojciech Samek, Klaus-Robert Müller, Sebastian Lapuschkin

Based on a recent technique - Spectral Relevance Analysis - we propose the following technical contributions and resulting findings: (a) a scalable quantification of artifactual and poisoned classes where the machine learning models under study exhibit CH behavior, (b) several approaches denoted as Class Artifact Compensation (ClArC), which are able to effectively and significantly reduce a model's CH behavior.
