Manifold-aware Forests: Closing the Gap to Convolutional Neural Networks
(Johns Hopkins UniversityUSA, 2020-05-05)Decision forests (DF), in particular random forests and gradient boosting trees, have demonstrated state-of-the-art accuracy compared to other methods in many supervised learning scenarios. In particular, DFs dominate ... -
Mapping of O-glycopeptides Using EXoO and a Novel Data Search Workflow
(Johns Hopkins UniversityUSA, 2020-05-12)Protein glycosylation is indisputably the most omnipresent protein modifications across mammalian cells. In eukaryotes, different types of oligosaccharides are linked to glycoproteins through two major types of glyosidic ... -
MAPPING OPTICAL PROPERTIES OF THE ESOPHAGUS USING SPATIAL FREQUENCY DOMAIN IMAGING
(Johns Hopkins UniversityUSA, 2018-05-07)The incidence of esophageal adenocarcinoma has continued to rise substantially, but the current standard of care for detecting cellular dysplasia and biopsy guidance has remained stagnant. Current white light endoscopy ... -
Mapping the Mechanobiome: Novel mathematically-derived 3D visualization of the cellular mechanoresponsive system for interactive publication
(Johns Hopkins UniversityUSA, 2019-03-23)Mechanical forces, ubiquitous in biological settings, are major determinants of cell fate; they should not be considered a detail applicable to specialized circumstances but rather a vital component of cell biology. To ... -
