| Abstract: | Objective To summarize the common recent decision tree algorithms and their applications in the field of health, and to provide reference for subsequent researches. Methods “Data mining”, “decision trees” were used as searching terms in CNKI, Wanfang, Weipu , PubMed database and so on from 2010 to 2019. The basic theory, steps, applicable conditions, advantages and disadvantages, applications in the field of heath of random forests, C5.0, GBDT and so on were summarized and listed. Results Different decision tree algorithms had their own advantages, and they had different degrees of applications in many subjects of health. Conclusion The recent decision tree algorithms are much better than the original algorithms, but they still have some defects. Promoting the applications of recent algorithms and improving their defects will be one of the important directions in the future. |
