Latest Patents

Zhang's latest patents focus on optimizing automated modeling algorithms for risk assessment and the generation of explanatory data. These patents detail a system that identifies predictor variables and generates a neural network to determine the relationship between each predictor variable and a risk indicator. The system performs factor analysis on the predictor variables to identify common factors and iteratively adjusts the neural network to ensure a monotonic relationship exists between each common factor and the risk indicator. Additionally, it ensures that the variance inflation factor for each common factor remains sufficiently low, indicating minimal multicollinearity. The adjusted neural network can then generate explanatory insights regarding the relationships between changes in the risk indicator and changes in the common factors.
