Latest Patents

Sara holds a patent for "Systems and methods for risk factor predictive modeling with dynamic training." This patent describes a system and method for dynamic model training of a predictive machine learning model that accesses data points from a training dataset, including a variety of model covariates. The model is designed to generate an output that includes a risk rank representative of mortality risk. The method involves selecting a covariate, generating a historical data distribution, and determining a current data distribution. If a significant shift in data distribution is detected, the model's parameters are automatically updated and retrained. This innovative approach employs covariate shift adaptation to ensure the model remains accurate and relevant.
