Graph Analysis and Graph Pooling in the Spatial Domain [article]

Mostafa Rahmani, Ping Li
2019 arXiv   pre-print
The proposed approach leverages a spatial representation of the graph which makes the neural network aware of the differences between the nodes and also their locations in the graph.  ...  The spatial representation which is equivalent to a point-cloud representation of the graph is obtained by a graph embedding method.  ...  Accordingly, in order to make the extracted local feature vectors a function of the role of the nodes in the structure of the graph, we propose the approach depicted by the red box in Figure 1 .  ...

Echoes of the Brain within the Posterior Cingulate Cortex

R. Leech, R. Braga, D. J. Sharp
2012 Journal of Neuroscience  
The PCC is a major node within the default mode network (DMN) and has high metabolic activity and dense structural connectivity to widespread brain regions, which suggests it has a role as a cortical hub  ...  However, recent nonhuman primate work provides evidence for a more active role in the control of cognition, through signaling an environmental change and the need to alter behavior.  ...  We have, therefore, used these labels to interpret the results of our analyses. The results of the two approaches to labeling the ROI-derived networks are qualitatively similar.  ...

Vision Transformer Equipped with Neural Resizer on Facial Expression Recognition Task [article]

Hyeonbin Hwang, Soyeon Kim, Wei-Jin Park, Jiho Seo, Kyungtae Ko, Hyeon Yeo
2022 arXiv   pre-print
As a remedy, Transformer has been introduced to vision fields with global receptive field, but requires adjusting input spatial size to the pretrained models to enjoy their strong inductive bias at hands  ...  In this work, we propose a novel training framework, Neural Resizer, to support Transformer by compensating information and downscaling in a data-driven manner trained with loss function balancing the  ...  Thus, we exploit a simple module, Spatial Transformer Network [25] , to align the necessary features before feeding to Super Resolution (SR) modules as an extended study.  ...

Wojciech Masarczyk, Przemysław Głomb, Bartosz Grabowski, Mateusz Ostaszewski
2020 Remote Sensing  
In this paper, we propose and investigate a simple and effective strategy of transfer learning that uses unsupervised pre-training step without label information.  ...  The transfer learning approach can be used to alleviate the second requirement for a particular dataset: first the network is pre-trained on some dataset with large amount of training labels available,  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.  ...

Fusion of multitemporal contextual information by neural networks for multisensor remote sensing image classification

Farid Melgani, Sebastiano B. Serpico, Gianni Vernazza
2003 Integrated Computer-Aided Engineering  
The neighboring class labels of a given pixel in the non-contextual classification map are exploited to extract spatial information, while temporal information is deduced from the non-contextual maps produced  ...  The first stage is a one-hidden layer MLP whose role is to estimate the single-time posterior probability of each class, given the feature vector.  ...  Spatial and temporal contextual information There may be different ways to model the spatial (or temporal) dependency among the labels in a spatial (or temporal) neighborhood.  ...

We attempt to improve AMR parsing by exploiting preposition semantic role labeling information retrieved from a multi-layer feed-forward neural network.  ...  Despite the usefulness of preposition semantic role labeling information for AMR parsing, it does not have an impact to the parsing F-score of CAMR, but reduces the parsing recall by 1%.  ...  Acknowledgments We would like to thank Sameer Pradhan for providing us with SRL parses of all task data.  ...
