Drishti: An mHealth platform for pervasive health monitoring

TL;DR: Here is an open-source mHealth framework based on FHIR! and here is the paper and my presentation at ICSE! Pervasive health monitoring is becoming less and less intrusive with better sensors, and more and more useful with machine learning and predictive analytics. mHealth (mobile health) could play an important part in pervasive health monitoring. […]

Machine Learning on Diabetic Retinopathy Images

Artificial intelligence (AI) and Machine Learning (ML) are having a profound impact on the way medicine is being practiced. AI/ML algorithms and techniques fit imaging applications easily and can help with automation. Radiology is the specialty that has benefitted the most from the AI/ML revolution. Melanoma detection in Dermatology is another obvious winner. Many of […]
