"Missing is useful": missing values in cost-sensitive decision trees

Shichao Zhang, Z. Qin, C.X. Ling, S. Sheng
2005 IEEE Transactions on Knowledge and Data Engineering  
We discuss and compare several strategies that utilize only known values and that "missing is useful" for cost reduction in cost-sensitive decision tree learning.  ...  In this paper, we study this issue in costsensitive learning that considers both test costs and misclassification costs.  ...  Thus, cost-sensitive decision tree learning algorithms would only need the known values and take advantage of "missing is useful" for cost reduction.  ...

Economic evaluation of the use of PCR assay in diagnosing pulmonary TB in a low-incidence area

I. Rajalahti, E‐L. Ruokonen, T. Kotomäki, H. Sintonen, M.M. Nieminen
2004 European Respiratory Journal  
A decision tree model based on retrospective laboratory data was developed to assess the strategies of testing patients with suspicion of TB.  ...  According to sensitivity analyses, reducing PCR test price, shortening test performance time or increasing the proportion of smear-positive patients in the tested population would contribute to cost savings  ...  In this analysis, the tree was used to calculate the expected cost per patient and the probability of correct treatment and isolation decisions for each strategy.  ...
