Modeling the Representation of Medial Axis Structure in Human Ventral Pathway Cortex
(Johns Hopkins University, 2016-07-21)
Computational modeling of the human brain has long been an important goal of scientific research. The visual system is of particular interest because it is one of the primary modalities by which we understand the world. ...
Using Machine Learning to Study the Relationship Between Galaxy Morphology and Evolution
(Johns Hopkins University, 2016-07-05)
We can track the physical evolution of massive galaxies over time by characterizing the morphological signatures inherent to different mechanisms of galactic assembly. Structural studies rely on a small set of measurements ...
Automated Virtual Coach for Surgical Training
(Johns Hopkins University, 2017-02-23)
Surgical educators have recommended individualized coaching for acquisition, retention and improvement of expertise in technical skills. Such one-on-one coaching is limited to institutions that can afford surgical coaches ...
Generative Non-Markov Models for Information Extraction
(Johns Hopkins University, 2016-02-22)
Learning from unlabeled data is a long-standing challenge in machine learning. A
principled solution involves modeling the full joint distribution over inputs
and the latent structure of interest, and imputing the missing ...
PREDICTION MODELS FOR CARBAPENEM-RESISTANT ENTEROBACTERIACEAE (CRE) AND OTHER MULTIDRUG-RESISTANT GRAM-NEGATIVE (MDRGN) BACTERIA IN HEALTHCARE SETTINGS
(Johns Hopkins University, 2018-10-01)
Background. Carbapenem-resistant Enterobacteriaceae (CRE) and other carbapenem-resistant organisms (CROs) pose urgent challenges to patient care. These bacteria are highly drug-resistant and are associated with significant ...
Learning Representations of Social Media Users
(Johns Hopkins University, 2018-10-25)
Social media users routinely interact by posting text updates, sharing images and videos, and establishing connections with other users through friending. User representations are routinely used in recommendation systems ...
Towards AI-assisted Healthcare: System Design and Deployment for Machine Learning based Clinical Decision Support
(Johns Hopkins University, 2018-05-10)
Over the last decade, American hospitals have adopted electronic health records (EHRs) widely. In the next decade, incorporating EHRs with clinical decision support (CDS) together into the process of medicine has the ...
A computational search for mutational drivers of cancer
(Johns Hopkins University, 2018-09-06)
The notion that DNA changes could drive the growth of cancer was first speculated more than a century ago, and has acquired overwhelming evidence in the past several decades. The recent decrease in cost of next-generation ...
Report Linking: Information Extraction for Building Topical Knowledge Bases
(Johns Hopkins University, 2017-10-26)
Human language artifacts represent a plentiful source of rich, unstructured information created by reporters, scientists, and analysts. In this thesis we provide approaches for adding structure: extracting and linking ...
Joint Spatial-Angular Sparse Coding, Compressed Sensing, and Dictionary Learning for Diffusion MRI
(Johns Hopkins University, 2018-03-02)
Neuroimaging provides a window into the inner workings of the human brain to diagnose and prevent neurological diseases and understand biological brain function, anatomy, and psychology. Diffusion Magnetic Resonance Imaging ...
