A Multimodal Type 2 Diabetes Registry on DHIS2: A Design and Feasibility Study with the AI-READI Dataset
Saptarshi Purkayastha, Aiswarya Nandan Perumbilly, Zhenan Yin +1
Care for type 2 diabetes increasingly draws on continuous glucose monitors, wearable devices, home sensors, clinical records and retinal images, yet few open platforms have been sh…
Preference vs. Performance: EEG-Based Classification of Learner Engagement in Multimodal Instruction
Sri Jahnavi Adusumilli, Deepak Giri, Pallavi Vaswani +4
Effective adaptive instructional systems require robust measures of learner engagement that go beyond static user profiles. This study employs Multimodal Learning Analytics (MMLA)…
Machine Learning for Pre-Culture ESBL Risk Stratification to Guide Empiric Antibiotic Selection: A 12-Hospital Study of Enterobacteriaceae Cultures
Aravind V. Kuruvikkattil, Lalitha Pranathi Pulavarthy, Rashmita Kudamala +1
Empiric antibiotic therapy for suspected ESBL-producing Enterobacteriaceae must be selected 48-72 hours before culture results, forcing clinicians to choose between undertreating r…
Predicting Early Functional Decline from Longitudinal Laboratory and Vital Sign Trajectories: A Large-Scale Study Using the All of Us Research Program
Rashmita Kudamala, Aravind V. Kuruvikkattil, Lalitha Pranathi Pulavarthy +1
Functional decline in older adults is typically recognized only after falls or observable gait impairment, closing the window for prevention. We investigated whether temporal traje…
Multimodal EEG-IMU Fusion for Motor Assessment: Leveraging Task-Dependent Complementarity for Robustness
Zhenan Yin, Lalitha Pranathi Pulavarthy, Saptarshi Purkayastha
Movement disorders such as Parkinson's disease require comprehensive motor assessment, but reliable digital assessment pipelines integrating multiple sensing modalities across dive…
Frozen Foundation-Model Embeddings Discard Small-Lesion Signal in Chest Radiography: Implications for Pre-Deployment Evaluation
Raajitha Muthyala, Zhenan Yin, Alekhya Jilla +6
Frozen vision-transformer (ViT) foundation-model embeddings increasingly serve as the substrate for downstream chest-radiography (CXR) pipelines, yet where small-scale, low-contras…
Human-Guided Agentic AI for Multimodal Clinical Prediction: Lessons from the AgentDS Healthcare Benchmark
Lalitha Pranathi Pulavarthy, Raajitha Muthyala, Aravind V Kuruvikkattil +3
Agentic AI systems are increasingly capable of autonomous data science workflows, yet clinical prediction tasks demand domain expertise that purely automated approaches struggle to…
Development of AI-integrated infrastructure with biomedical device and mobile app for neonatal vital monitoring during and in between kangaroo care sessions
Saptarshi Purkayastha, Hrishikesh Bhagwat, Keerthika Sunchu +6
Premature infant mortality remains a critical challenge in low- and middle-income countries (LMICs), with continuous vital sign monitoring being essential for early detection of li…
