Data-driven techniques have recently drawn significant interest in the predictive modeling of subcutaneous (s.c.) glucose concentration type 1 diabetes. In this study, s.c. prediction is treated as a multivariate regression problem, which addressed using support vector (SVR). The proposed method based on variables concerning: (i) profile, (ii) plasma insulin concentration, (iii) appearance meal-derived systemic circulation, and (iv) energy expenditure during physical activities. Six cases...

METABO is a diabetes monitoring and management system which aims at recording interpreting patient's context, as well as, providing decision support to both the patient doctor. The consists of (a) Patient's Mobile Device (PMD), (b) different types unobtrusive biosensors, (c) Central Subsystem (CS) located remotely hospital (d) Control Panel (CP) from physicians can follow-up their patients gain also access CS. provides multi-parametric facilitates efficient systematic dietary, physical...
In this study, an individualized predictive model of the subcutaneous glucose concentration in type 1 diabetes is presented, which relies on Random Forests regression technique. A multivariate dataset utilized concerning s.c. profile, plasma insulin concentration, intestinal absorption meal-derived and daily energy expenditure. attempt to capture rhythms metabolism, we also introduce a time feature analysis. The comes from continuous multi-day recordings 27 patients free-living conditions....
We propose an online machine-learning solution to the problem of nonlinear glucose time series prediction in type 1 diabetes. Recently, extreme learning machine (ELM) has been proposed for training single hidden layer feed-forward neural networks. The high accuracy and fast speed ELM drive us investigate its applicability problem. Given that diabetes self-monitoring data are received sequentially, we focus on sequential (OS-ELM) kernels (KOS-ELM). A multivariate feature set is utilized...
Type 1 diabetes (T1D) is a chronic endocrine disorder characterized by high blood glucose levels, impacting millions of people globally. Its management requires intensive insulin therapy, frequent monitoring, and lifestyle adjustments. The accurate prediction the short-term course levels in subcutaneous space T1D people, as measured continuous monitoring (CGM) system, essential for improving control avoiding harmful hypoglycaemic hyperglycaemic swings, facilitating precise individualized...
The emergency of cloud computing and Generic Enablers (GEs) as the building blocks Future Internet (FI) applications highlights new requirements in area services. Though, due to current restrictions various certification standards related with privacy safety health data, utilization such has been many instances unlawful. Here, we focus on demonstrating a “software data” provisioning solution propose mapping FI application use case software specifications (using GEs). aim is establish...
We propose a non-linear recursive solution to the problem of short-term prediction glucose in type 1 diabetes. The Fixed Budget Quantized Kernel Least Mean Square (QKLMS-FB) algorithm is employed construct univariate model subcutaneous concentration, which: (i) handles nonlinearities by transforming input space into high-dimensional Reproducing Hilbert Space and, (ii) finds sparse retaining representative subset training vectors. dataset comes from continuous multi-day recordings 15 patients...

Diabetic patients must adhere continually to a complex daily regime in order maintain the blood glucose levels within safe range. Many factors impact variations such as diet, medication and exercise. This work presents modeling methodology for prediction type 1 diabetic patients. The physiological processes related diabetes (i.e. insulin absorption, gut absorption) well effects of exercise on dynamics are quantified using compartmental models. Furthermore, method employs Support Vector...
In this work, we present a novel computational approach for the prediction of atherosclerotic plaque growth. particular, patient-specific coronary computed tomography angiography (CCTA) data were collected from 60 patients at two time points.
