VARIATIONAL METHOD OF MAXIMIZING CONDITIONAL EVIDENCE FOR LATENT VARIABLE MODELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240104354 titled 'VARIATIONAL METHOD OF MAXIMIZING CONDITIONAL EVIDENCE FOR LATENT VARIABLE MODELS
Simplified Explanation
The computer-implemented method described in the abstract is for learning with incomplete data, specifically focusing on maximizing a stochastically approximated conditional evidence lower bound to learn an unknown parameter in the predictive distribution of an outcome.
- Acquiring an incomplete set of covariates and an incomplete pattern indicating missing entries.
- Obtaining a predictive distribution of an outcome using the incomplete set of covariates and an unknown parameter.
- Learning the unknown parameter by maximizing a stochastically approximated conditional evidence lower bound.
- Controlling a density ratio by transforming parameters to keep the gradient below a threshold during maximization.
Potential Applications
This technology could be applied in fields such as machine learning, data analysis, and predictive modeling where incomplete data is common.
Problems Solved

Original Abstract Submitted
a computer-implemented method is provided for learning with incomplete data in which some of entries are missing. the method includes acquiring an incomplete set of covariates including incomplete features {tilde over (x)} and an incomplete pattern m indicating missing entries of the incomplete set of covariates {tilde over (x)}. the method further includes obtaining, by a hardware processor, a predictive distribution p(y|) of an outcome y by using the incomplete set of covariates and a parameter �, the parameter � being unknown. a learning of the parameter � includes performing a maximization by maximizing a stochastically approximated conditional evidence lower bound. the stochastically approximated conditional evidence lower bound includes a density ratio which is controlled by transforming a portion of parameters of the stochastically approximated conditional evidence lower bound to keep a gradient of the stochastically approximated conditional evidence lower bound below a threshold during the maximization.
