Enclave-based oblivious RAM using Intel's SGX
( Elsevier , 2020 , Article)Oblivious RAM (ORAM) schemes exist in order to protect the access pattern of data in a data store. Under an ORAM algorithm, a client accesses a data store in such a way that does not reveal which item it is interested in. ... -
Efficient sanitization of unsafe data correlations
( CEUR-WS , 2015 , Conference Paper)In this paper, we present a study to counter privacy violation due to unsafe data correlation. We propose a safe correlation requirement to keep correlated values bounded by l-diversity and evaluate the trade-off to be ... -
Temporal self-attention for risk prediction from electronic health records using non-stationary kernel approximation
( Elsevier , 2024 , Article)Effective modeling of patient representation from electronic health records (EHRs) is increasingly becoming a vital research topic. Yet, modeling the non-stationarity in EHR data has received less attention. Most existing ... -
Predicting emergency department utilization among children with asthma using deep learning models
( Elsevier , 2022 , Article)Pediatric asthma is a leading cause of emergency department (ED) utilization, which is expensive and often preventable. Therefore, development of ED utilization predictive models that can accurately predict patients at ... -
PredictPTB: an interpretable preterm birth prediction model using attention-based recurrent neural networks
( BioMed Central Ltd , 2022 , Article)Background: Early identification of pregnant women at risk for preterm birth (PTB), a major cause of infant mortality and morbidity, has a significant potential to improve prenatal care. However, we lack effective predictive ... -
Privacy-preserving Deep-learning Models for Fingerprint Data using Differential Privacy
