Identifying Weekly Trajectories of Pain Severity Using Daily Data From an mHealth Study: Cluster Analysis

Identifying Weekly Trajectories of Pain Severity Using Daily Data From an mHealth Study: Cluster Analysis

Once identified, weekly pain trajectories could be forecast. People living with chronic pain have reported that a pain forecast would reduce unpredictability and could be used to support planning daily activities, such as shopping, chores, and social participation [20,21].

Participatory Surveillance for COVID-19 Trend Detection in Brazil: Cross-sectional Study

Participatory Surveillance for COVID-19 Trend Detection in Brazil: Cross-sectional Study

The combination model outperformed the baseline model for the 14-day forecast by up to 2.7%. The results for the 7-day forecast were ambiguous; while there were improvements of up to 4.1%, only 2 out of the 3 cities showed reduced RMSEs. Forecasting errors using different models for 1-day, 7-day, and 14-day forecasts in the city of Teresina. a The models used n=13 lagged components as independent variables. b RMSE: root mean squared error. c MAE: mean absolute error.

Effects of a Novel Blood Glucose Forecasting Feature on Glycemic Management and Logging in Adults With Type 2 Diabetes Using One Drop: Retrospective Cohort Study

Effects of a Novel Blood Glucose Forecasting Feature on Glycemic Management and Logging in Adults With Type 2 Diabetes Using One Drop: Retrospective Cohort Study

There are few existing examples of machine learning used to forecast future events for persons with diabetes. In one example, the need for pharmacological therapy was forecast for patients with gestational diabetes [19]. In another study, infections and hypoglycemic events were accurately forecast for individuals with type 1 diabetes (T1 D) [20,21].

How New Mexico Leveraged a COVID-19 Case Forecasting Model to Preemptively Address the Health Care Needs of the State: Quantitative Analysis

How New Mexico Leveraged a COVID-19 Case Forecasting Model to Preemptively Address the Health Care Needs of the State: Quantitative Analysis

To forecast the DHR into the future, DHR(t)', we calculated a 2-week time-weighted average of the DHR and then assumed this DHR would persist throughout the forecast duration. Where t= 0 is the last day of the observed data, the weight of each DHR (t – n) for n = 0: 13 was determined as The DHR is a convenient ratio that is obtainable from available data.

Machine Learning–Based Prediction of Growth in Confirmed COVID-19 Infection Cases in 114 Countries Using Metrics of Nonpharmaceutical Interventions and Cultural Dimensions: Model Development and Validation

Machine Learning–Based Prediction of Growth in Confirmed COVID-19 Infection Cases in 114 Countries Using Metrics of Nonpharmaceutical Interventions and Cultural Dimensions: Model Development and Validation

Many epidemiological models that forecast future infection numbers have therefore suggested the role of NPIs in reducing infection rates [2,4,7,12], which can aid the implementation of national strategies and policy decision-making. Recent research incorporates publicly available data with machine learning for use cases such as reported infection case number forecasting [13-16].
