Frozen Feature Augmentation for Few-Shot Image Classification

no code implementations15 Mar 2024 Andreas Bär, Neil Houlsby, Mostafa Dehghani, Manoj Kumar

Training a linear classifier or lightweight model on top of pretrained vision model outputs, so-called 'frozen features', leads to impressive performance on a number of downstream few-shot tasks.

Detecting Adversarial Perturbations in Multi-Task Perception

1 code implementation2 Mar 2022 Marvin Klingner, Varun Ravi Kumar, Senthil Yogamani, Andreas Bär, Tim Fingscheidt

In this paper, we (i) propose a novel adversarial perturbation detection scheme based on multi-task perception of complex vision tasks (i. e., depth estimation and semantic segmentation).

Improving Online Performance Prediction for Semantic Segmentation

no code implementations12 Apr 2021 Marvin Klingner, Andreas Bär, Marcel Mross, Tim Fingscheidt

In this work we address the task of observing the performance of a semantic segmentation deep neural network (DNN) during online operation, i. e., during inference, which is of high importance in safety-critical applications such as autonomous driving.

Transferable Universal Adversarial Perturbations Using Generative Models

no code implementations28 Oct 2020 Atiye Sadat Hashemi, Andreas Bär, Saeed Mozaffari, Tim Fingscheidt

Using our generated non-targeted UAPs, we obtain an average fooling rate of 93. 36% on the source models (state of the art: 82. 16%).

Class-Incremental Learning for Semantic Segmentation Re-Using Neither Old Data Nor Old Labels

1 code implementation12 May 2020 Marvin Klingner, Andreas Bär, Philipp Donn, Tim Fingscheidt

While neural networks trained for semantic segmentation are essential for perception in autonomous driving, most current algorithms assume a fixed number of classes, presenting a major limitation when developing new autonomous driving systems with the need of additional classes.

Improved Noise and Attack Robustness for Semantic Segmentation by Using Multi-Task Training with Self-Supervised Depth Estimation

no code implementations23 Apr 2020 Marvin Klingner, Andreas Bär, Tim Fingscheidt

We show the effectiveness of our method on the Cityscapes dataset, where our multi-task training approach consistently outperforms the single-task semantic segmentation baseline in terms of both robustness vs. noise and in terms of adversarial attacks, without the need for depth labels in training.

Towards Corner Case Detection for Autonomous Driving

no code implementations25 Feb 2019 Jan-Aike Bolte, Andreas Bär, Daniel Lipinski, Tim Fingscheidt

The progress in autonomous driving is also due to the increased availability of vast amounts of training data for the underlying machine learning approaches.
