Grid Saliency for Context Explanations of Semantic Segmentation [article]

Lukas Hoyer, Mauricio Munoz, Prateek Katiyar, Anna Khoreva, Volker Fischer
2019 arXiv   pre-print
As the proposed grid saliency allows to spatially disentangle the object and its context, we specifically explore its potential to produce context explanations for semantic segmentation networks, discovering  ...  Our results show that grid saliency can be successfully used to provide easily interpretable context explanations and, moreover, can be employed for detecting and localizing contextual biases present in  ...  We showcase the usability of grid saliency for context explanations of semantic segmentation (see Sec. 4 and 5).  ...

Alvin Wan, Daniel Ho, Younjin Song, Henk Tillman, Sarah Adel Bargal, Joseph E. Gonzalez
2020 arXiv   pre-print
We obtain semantic visual meaning by extending saliency methods to segmentation and attain accuracy by leveraging insights from neural-backed decision trees, a deep learning analog of decision trees for  ...  However, such models (1) perform poorly when compared to state-of-the-art segmentation models or (2) fail to produce decision rules with spatially-grounded semantic meaning.  ...  We furthermore propose extensions for saliency methods -the spatially-aware Grad-PAM and semantically-aware SIR -to uncover semantic, visual decision rules in our neural-backed decision tree for segmentation  ...

Salience and metaphysical explanation

Phil Corkum
2021 Synthese  
I argue that such explanations exhibit salience failure. How ought we represent the semantics of salience?  ...  of focus sensitivity to sketch how one might model the role of salience in these kinds of explanations.  ...  But analogous semantic differences may be induced by the context of the explanation.  ...

Background-Aware Pooling and Noise-Aware Loss for Weakly-Supervised Semantic Segmentation [article]

Youngmin Oh, Beomjun Kim, Bumsub Ham
2021 arXiv   pre-print
We address the problem of weakly-supervised semantic segmentation (WSSS) using bounding box annotations.  ...  This allows to extract high-quality pseudo segmentation labels to train CNNs for semantic segmentation, but the labels still contain noise especially at object boundaries.  ...  Classifier for semantic segmentation Here we provide a detailed description of two different classifiers for semantic segmentation.  ...

Unsupervised Semantic Segmentation by Contrasting Object Mask Proposals [article]

Wouter Van Gansbeke, Simon Vandenhende, Stamatios Georgoulis, Luc Van Gool
2021 arXiv   pre-print
Being able to learn dense semantic representations of images without supervision is an important problem in computer vision.  ...  Under the fully unsupervised setting, there is no precedent in solving the semantic segmentation task on such a challenging benchmark.  ...  The combination of these two properties results in image representations that can be directly clustered into semantic groups (see also [73] for a more detailed explanation).  ...

Explainability of deep vision-based autonomous driving systems: Review and challenges [article]

Éloi Zablocki, Hédi Ben-Younes, Patrick Pérez, Matthieu Cord

Survival processing modulates the neurocognitive mechanisms of episodic encoding

Glen Forester, Meike Kroneisen, Edgar Erdfelder, Siri-Maria Kamp
2020 Cognitive, Affective, & Behavioral Neuroscience  
The results are consistent with a richness of encoding account of the survival processing effect and offer novel insights into the encoding processes that lead to enhanced memory for fitness-relevant information  ...  Memories formed in the context of an imagined survival scenario are more easily remembered, but the mechanisms underlying this effect are still under debate.  ...  Thus, one explanation for the decreased false memory in the present study could be that the strength of semantic associations within our word list was in fact relatively low.  ...

Video segmentation by tracing discontinuities in a trajectory embedding

K. Fragkiadaki, Geng Zhang, Jianbo Shi
2012 2012 IEEE Conference on Computer Vision and Pattern Recognition  
For segmenting articulated objects, we combine motion grouping cues with a centersurround saliency operation, resulting in "context-aware", spatially coherent, saliency maps.  ...  Detected discontinuities are strong indicators of object boundaries and thus valuable for video segmentation.  ...  Acknowledgments The authors would like to thank Kosta Derpanis, Elena Bernardis, Weiyu Zhang and Ben Sapp for useful discussions on the writing of this paper.  ...
