SOAP: Cross-sensor Domain Adaptation for 3D Object Detection Using Stationary Object Aggregation Pseudo-labelling

no code implementations8 Jan 2024 Chengjie Huang, Vahdat Abdelzad, Sean Sedwards, Krzysztof Czarnecki

We consider the problem of cross-sensor domain adaptation in the context of LiDAR-based 3D object detection and propose Stationary Object Aggregation Pseudo-labelling (SOAP) to generate high quality pseudo-labels for stationary objects.

XC: Exploring Quantitative Use Cases for Explanations in 3D Object Detection

1 code implementation20 Oct 2022 Sunsheng Gu, Vahdat Abdelzad, Krzysztof Czarnecki

We evaluate the effectiveness of XC scores via the task of distinguishing true positive (TP) and false positive (FP) detected objects in the KITTI and Waymo datasets.

LiDAR-MIMO: Efficient Uncertainty Estimation for LiDAR-based 3D Object Detection

no code implementations1 Jun 2022 Matthew Pitropov, Chengjie Huang, Vahdat Abdelzad, Krzysztof Czarnecki, Steven Waslander

The estimation of uncertainty in robotic vision, such as 3D object detection, is an essential component in developing safe autonomous systems aware of their own performance.

The missing link: Developing a safety case for perception components in automated driving

no code implementations30 Aug 2021 Rick Salay, Krzysztof Czarnecki, Hiroshi Kuwajima, Hirotoshi Yasuoka, Toshihiro Nakae, Vahdat Abdelzad, Chengjie Huang, Maximilian Kahn, Van Duong Nguyen

In this paper, we propose the Integration Safety Case for Perception (ISCaP), a generic template for such a linking safety argument specifically tailored for perception components.

The Effect of Optimization Methods on the Robustness of Out-of-Distribution Detection Approaches

no code implementations25 Jun 2020 Vahdat Abdelzad, Krzysztof Czarnecki, Rick Salay

In addition to comparing several OODD approaches using our proposed robustness score, we demonstrate that some optimization methods provide better solutions for OODD approaches.

Improving Confident-Classifiers For Out-of-distribution Detection

1 code implementation25 Sep 2019 Sachin Vernekar, Ashish Gaurav, Vahdat Abdelzad, Taylor Denouden, Rick Salay, Krzysztof Czarnecki

In the context of OOD detection for image classification, one of the recent approaches proposes training a classifier called “confident-classifier” by minimizing the standard cross-entropy loss on in-distribution samples and minimizing the KLdivergence between the predictive distribution of OOD samples in the low-density“boundary” of in-distribution and the uniform distribution (maximizing the entropy of the outputs).

Analysis of Confident-Classifiers for Out-of-distribution Detection

1 code implementation27 Apr 2019 Sachin Vernekar, Ashish Gaurav, Taylor Denouden, Buu Phan, Vahdat Abdelzad, Rick Salay, Krzysztof Czarnecki

Discriminatively trained neural classifiers can be trusted, only when the input data comes from the training distribution (in-distribution).

Improving Reconstruction Autoencoder Out-of-distribution Detection with Mahalanobis Distance

no code implementations6 Dec 2018 Taylor Denouden, Rick Salay, Krzysztof Czarnecki, Vahdat Abdelzad, Buu Phan, Sachin Vernekar

There is an increasingly apparent need for validating the classifications made by deep learning systems in safety-critical applications like autonomous vehicle systems.

Calibrating Uncertainties in Object Localization Task

no code implementations27 Nov 2018 Buu Phan, Rick Salay, Krzysztof Czarnecki, Vahdat Abdelzad, Taylor Denouden, Sachin Vernekar

In many safety-critical applications such as autonomous driving and surgical robots, it is desirable to obtain prediction uncertainties from object detection modules to help support safe decision-making.
