Exploring Deep Learning and Transfer Learning for Colonic Polyp Classification
TL;DR: This work explores Deep Learning for the automated classification of colonic polyps using different configurations for training CNNs from scratch and distinct architectures of pretrained CNNs tested on 8-HD-endoscopic image databases acquired using different modalities and suggests the combination of classical features and “off-the-shelf” CNNs features can be a good approach to further improve the results.
Journal ArticleDOI
Successful antibiotic treatment of Helicobacter pylori negative gastric mucosa associated lymphoid tissue lymphomas
TL;DR: Patients with early stage gastric MALT lymphoma negative for H pylori might still benefit from antibiotic treatment as the sole treatment modality.
Proceedings ArticleDOI
Colonic Polyp Classification with Convolutional Neural Networks
TL;DR: This paper proposes the use of CNN's for the automated classification of colonic mucosa for colon polyp staging in the context of colon cancer screening and shows experimentally that this model is more efficient than some of the commonly used features for colonic polyp classification.

TL;DR: Within 24 h after ROSC there was a significant improvement in SEP, and it is recommended to allow a period of at least 24 H after cardiopulmonary resuscitation for obtaining a reliable prognosis based on SEP.
