Knowledge Enhanced Conditional Imputation
Knowledge enhanced conditional imputation aims to accurately fill in missing data points in datasets, particularly those with complex structures like time series or multi-modal data, leveraging existing knowledge to improve imputation accuracy. Current research emphasizes the use of advanced machine learning models, including transformers, graph neural networks, and recurrent neural networks, often incorporating techniques like manifold learning and multilinear kernel regression to capture intricate data relationships. This field is crucial for improving the reliability and utility of data in various applications, from healthcare predictions and recommendation systems to environmental monitoring and structural health monitoring, where missing data is a common and significant challenge.
