Automated insulin delivery for hypoglycemia avoidance and glucose counterregulation in long-standing type 1 diabetes with hypoglycemia unawareness

Published in Diabetes Technology and Therapeutics, 2023

Automated insulin delivery (AID) may benefit individuals with long-standing type 1 diabetes where frequent exposure to hypoglycemia impairs counterregulatory responses. This study assessed the effect of 18 months AID on hypoglycemia avoidance and glucose counterregulatory responses to insulin-induced hypoglycemia in long-standing type 1 diabetes complicated by impaired awareness of hypoglycemia.

Sequential Covariate Shift Detection Using Classifier Two-Sample Tests

Published in International Conference on Machine Learning (ICML), 2022

A standard assumption in supervised learning is that the training data and test data are from the same distribution. However, this assumption often fails to hold in practice, which can cause the learned model to perform poorly. We consider the problem of detecting covariate shift, where the covariate distribution shifts but the conditional distribution of labels given covariates remains the same. Read more

Improving Classifier Confidence using Lossy Label-Invariant Transformations

Published in International Conference on Artificial Intelligence and Statistics (AISTATS), 2021

Providing reliable model uncertainty estimates is imperative to enabling robust decision making by autonomous agents and humans alike. In this paper, we present the recursive lossy label-invariant calibration (ReCal) technique that leverages label-invariant transformations to recursively group (and calibrate) inputs. We show that ReCal outperforms other calibration methods on multiple datasets, especially, on large-scale datasets such as ImageNet. Read more

Characterizing Glycemic Control and Sleep in Adults with Long-Standing Type 1 Diabetes and Hypoglycemia Unawareness Initiating Hybrid Closed Loop Insulin Delivery

Published in Journal of Diabetes Research, 2021

Nocturnal hypoglycemia is life threatening for individuals with type 1 diabetes (T1D) due to loss of hypoglycemia symptom recognition (hypoglycemia unawareness) and impaired glucose counter regulation. These individuals also show disturbed sleep, which may result from glycemic dysregulation. The purpose of this study was to describe long-term changes in glycemic control and objective sleep after initiating hybrid closed loop (HCL) insulin delivery in adults with type 1 diabetes and hypoglycemia unawareness.
