Abstract

With the development of information technology, a large amount of multi-view data continues to emerge in the financial field. The absence of these multi-view data samples limits the research processing of financial data, while the popular single-view filling algorithm cannot handle the problem of missing multi-view data well. To address this problem, this study proposes a new filling method called Weighted Multi-view Random Forest (WMVRF), which innovatively combines feature importance to calculate view weights and enables missing filling of multi-view data by integrating the label prediction results from multiple views random forests. Several filling algorithms such as MissForest, Generative Adversarial Imputation Network, and KNN are compared on one real dataset and four multi-view public datasets (Handwritten, Webkb, 3Sources, BBCSport). The experimental results show that the proposed method reduces the normalized root mean square error (NRMSE) by 1.6% and outperforms the KNN, GAIN, and EM filling algorithms on the financial dataset compared to RF.
