[Purpose/Significance]Timely and accurate identification of transformative research is of great signifi-cance for exploring the research frontiers in science,as well as facing the new pattern of high-quality development of the country.[Method/Process]Based on the characteristics of transformative research in the dimensions of breadth,intensity and speed,and by machine learning methods,the entropy weight method,factor analysis method and regression analysis method,the study constructed the transformative research identification model from the perspective of citation.Applied the models above to the fields of gene targets,magnetoresistive effects,fullerenes to evaluate the early recognition effect of dif-ferent models,and applied the model with the highest early recognition effect to the fields of molecular biology,polymer science and astrophysics in 2017.[Results/Conclusions]Judging from the"ranking"and"top%"indicators,the rec-ognition effect of the early recognition model of transformative research based on regression analysis is better than that of the other two models,and the identified transformative research ranks higher,and the transformative research could be identi-fied in the third year after publication.The accuracy of the model in the field of gene targets and fullerenes are higher than in the field of magnetoresistive effect.The accuracy and recall rate of the early recognition model in the transformative study based on regression analysis are 80%,and the average score of the model is 0'764.
