An embedded imputation method via Attribute-based Decision Graphs
作者:
Highlights:
• Attribute-based Decision Graphs represent the correlation among data attributes.
• Similar data instances induce similar subgraphs in the AbDG.
• Imputation partially matches instances to the AbDG searching for a proper subgraph.
• The method has low computational costs and handles high rates of missing values.
• Results show the method is efficient to impute data prior to classification tasks.
