This thesis presents developments in computer vision models' robustness and explainability.

Adversarial Attack Explainable Models

Artifact Reduction in 3D and 4D Cone-beam Computed Tomography Images with Deep Learning -- A Review

no code implementations27 Mar 2024 Mohammadreza Amirian, Daniel Barco, Ivo Herzig, Frank-Peter Schilling

Deep learning based approaches have been used to improve image quality in cone-beam computed tomography (CBCT), a medical imaging technique often used in applications such as image-guided radiation therapy, implant dentistry or orthopaedics.

Trace and Detect Adversarial Attacks on CNNs using Feature Response Maps

no code implementations24 Aug 2022 Mohammadreza Amirian, Friedhelm Schwenker, Thilo Stadelmann

The existence of adversarial attacks on convolutional neural networks (CNN) questions the fitness of such models for serious applications.

Radial Basis Function Networks for Convolutional Neural Networks to Learn Similarity Distance Metric and Improve Interpretability

1 code implementation24 Aug 2022 Mohammadreza Amirian, Friedhelm Schwenker

In this paper, we adapt RBF networks as a classifier on top of CNNs by modifying the training process and introducing a new activation function to train modern vision architectures end-to-end for image classification.

Deep Learning in the Wild

no code implementations13 Jul 2018 Thilo Stadelmann, Mohammadreza Amirian, Ismail Arabaci, Marek Arnold, Gilbert François Duivesteijn, Ismail Elezi, Melanie Geiger, Stefan Lörwald, Benjamin Bruno Meier, Katharina Rombach, Lukas Tuggener

Deep learning with neural networks is applied by an increasing number of people outside of classic research environments, due to the vast success of the methodology on a wide range of machine perception tasks.

Learning Neural Models for End-to-End Clustering

1 code implementation11 Jul 2018 Benjamin Bruno Meier, Ismail Elezi, Mohammadreza Amirian, Oliver Durr, Thilo Stadelmann

We propose a novel end-to-end neural network architecture that, once trained, directly outputs a probabilistic clustering of a batch of input examples in one pass.
