Bipartite Graph Network with Adaptive Message Passing for Unbiased Scene Graph Generation [article]

Rongjie Li, Songyang Zhang, Bo Wan, Xuming He
2021 arXiv   pre-print
Despite recent tremendous progress, it remains challenging due to the intrinsic long-tailed class distribution and large intra-class variation.  ...  In addition, we propose an efficient bi-level data resampling strategy to alleviate the imbalanced data distribution problem in training our graph network.  ...  Moreover, as shown in Fig. 5 , we compute the mean recall on each long-tail category groups in SGGen subtask and find BGNN significantly outperforms the prior works [27, 39] on tail group, as a result  ...

"Snake": One more Terramorphic Entity of the Hypothetical Venus Fauna

Leonid Ksanfomality
2013 International Letters of Chemistry, Physics and Astronomy  
Analysis of treated once gain VENERA-13 and VENERA-14 panoramic images revealed (among other hypothetic living entities) a 'snake' object about 40 cm in size possessing apparent terramorphic features.  ...  The 'snake' can be included into the list of the most significant findings of the hypothetical Venusian fauna.  ...  Compared with the original images, the brightness and contrast of the images in Fig. 4 have been leveled. The 'extraneous entity' is in the center of each shot.  ...

Intraductal Tubular Carcinoma of the Pancreas: a Case Report with the Imaging Findings

Dae Kun Oh, Seong Hyun Kim, Seoung Ho Choi, Kee-Taek Jang
2008 Korean Journal of Radiology  
However, on the imaging findings, making the diagnosis of ITC from the imaging findings can be confused with that of an IPMN, and especially for the main duct type IPMN because of the similar imaging findings  ...  Based on the imaging findings of the present case, the imaging finding of an IPMN shows the dilatation of mainly the downstream main pancreatic duct, which is caused by the hypersecretion of mucin.  ...

Exploring the Long Tail of Social Media Tags [chapter]

Svetlana Kordumova, Jan van Gemert, Cees G. M. Snoek
2016 Lecture Notes in Computer Science  
In this paper we investigate what social tags constitute the long tail and how they perform on two multimedia retrieval scenarios, tag relevance and detector learning.  ...  We show common valuable tags within the long tail, and by augmenting them with semantic knowledge, the performance of tag relevance and detector learning improves substantially.  ...  This research is supported by the STW STORY project and the Dutch national program COMMIT.  ...

Pancreatic pseudopapillary tumour: A rare misdiagnosed entity

C.A. Affirul, F.N. Qisti, Z. Zamri, A. Azlanuddin, A.O. Hairol, J. Razman
2014 International journal of surgery case reports  
The common location in the pancreatic head and tail often necessitates surgical intervention.  ...  Nevertheless, it has been shown to be premalignant in nature. It is difficult to diagnose as the presentation varies from non-specific abdominal pain to incidental findings in asymptomatic patients.  ...

VideoLT: Large-scale Long-tailed Video Recognition [article]

Xing Zhang, Zuxuan Wu, Zejia Weng, Huazhu Fu, Jingjing Chen, Yu-Gang Jiang, Larry Davis
2021 arXiv   pre-print
Through extensive studies, we demonstrate that state-of-the-art methods used for long-tailed image recognition do not perform well in the video domain due to the additional temporal dimension in video  ...  While long-tailed recognition has been extensively studied for image classification tasks, limited effort has been made for video domain.  ...  Acknowledgement This work was supported in part by National Natural Science Foundation of China (#62032006).  ...

Giant ranula of the neck: differentiation from cystic hygroma

Andre J Macdonald, Karen L Salzman, H Ric Harnsberger
2003 American Journal of Neuroradiology  
Our purpose was to review the imaging findings of giant ranula and compare them with those of cystic hygroma to define those features that are helpful in differentiating these different disease entities  ...  Although giant ranulas may superficially resemble cystic hygroma, several imaging features allow confident differentiation of these two entities.  ...  Giant Ranula Imaging Findings The imaging findings of all cases of giant ranula (six of six cases) were similar.  ...

A case report with sacral appendage: is it accessory penis or human tail?

Canan Kocaoğlu, Çelebi Kocaoğlu, İbrahim Akkoyun, İlkay Eren Karaniş
2017 Turkish Journal of Pediatrics  
However, if this lesion is a pseudotail, it may be an anomalous prolongation of the coccygeal vertebra, lipoma, teratoma, condrodystrophy or parasitic fetus.  ...  It is difficult to say that they are a evolutionary inheritance (tail) from our ancestors or an anomaly (pseudotail) occuring during embrional development.  ...  Discussion The fetal tails usually disappear by the end of the gestational 8th week in human beings. After delivery, the caudal appendage resembling a tail is a quite rare entity 1 .  ...

Second brachial cleft cyst mimic: case report

Philip D Lanham, Curtis Wushensky
2005 American Journal of Neuroradiology  
We report the CT findings in a patient with a lateral neck mass histologically shown to be a schwannoma but having certain radiographic features commonly considered pathognomonic for a type III second  ...  Our case, therefore, represents an exception to this long-established rule.  ...  Consequently, although this "tail sign" is still strongly suggestive of a type III second BCC, it can no longer be considered pathognomonic for that disease entity.  ...
