Sparse Linear Combination of Soms for Data Imputation: Application to Financial Database
Abstract
This Paper Presents a New Methodology for Missing Value Imputation in a Database. the Methodology Combines the Outputs of Several Self-Organizing Maps in Order to Obtain an Accurate Filling for the Missing Values. the Maps Are Combined using Multiresponse Sparse Regression and the Hannan-Quinn Information Criterion. the New Combination Methodology Removes the Need for Any Lengthy Cross-Validation Procedure, Thus Speeding Up the Computation Significantly. Furthermore, the Accuracy of the Filling is Improved, as Demonstrated in the Experiments. © 2009 Springer-Verlag Berlin Heidelberg.
