Active Learning Pipeline for Brain Mapping in a High Performance Computing Environment
This paper describes a scalable active learning pipeline prototype for
large-scale brain mapping that leverages high performance computing power. It
enables high-throughput evaluation of algorithm results, which, after human
review, are used for iterative machine learning model training. Image
processing and machine learning are performed in a batch layer. Benchmark
testing of image processing using pMATLAB shows that a 100 increase in
throughput (10,000%) can be achieved while total processing time only increases
by 9% on Xeon-G6 CPUs and by 22% on Xeon-E5 CPUs, indicating robust
scalability. The images and algorithm results are provided through a serving
layer to a browser-based user interface for interactive review. This pipeline
has the potential to greatly reduce the manual annotation burden and improve
the overall performance of machine learning-based brain mapping.Comment: 6 pages, 5 figures, submitted to IEEE HPEC 2020 proceeding

The role of primary care providers in testing for sexually transmitted infections in the MassHealth Medicaid program.
The objective of this study was to determine the prevalence and predictors of testing for sexually transmitted infections (STIs) under an accountable care model of health care delivery. Data sources were claims and encounter records from the Massachusetts Medicaid and Children's Health Insurance Program (MassHealth) for enrollees aged 13 to 64 years in 2019. This cross-sectional study examines the one-year prevalence of STI testing and evaluates social determinants of health and other patient characteristics as predictors of such testing in both primary care and other settings. We identified visits with STI testing using procedure codes and primary care settings from provider code types. Among 740,417 members, 55% were female, 11% were homeless or unstably housed, and 15% had some level of disability. While the prevalence of testing in any setting was 20% (N = 151,428), only 57,215 members had testing performed in a primary care setting, resulting in an 8% prevalence of testing by primary care clinicians (PCCs). Members enrolled in a managed care organization (MCO) were significantly less likely to be tested by a primary care provider than those enrolled in accountable care organization (ACO) plans that have specific incentives for primary care practices to coordinate care. Enrollees in a Primary Care ACO had the highest rates of STI testing, both overall and by primary care providers. Massachusetts' ACO delivery systems may be able to help practices increase STI screening with explicit incentives for STI testing in primary care settings
