Embodiment
[0036] Embodiment 1 The establishment of a method for predicting the risk of myeloma based on the GBDT model.
[0037]GBDT (Gradient Boosting DecisionTree) is an integrated learning algorithm, which consists of DecisionTree (decision tree) and Gradient Boosting (gradient boosting). The GBDT output is the accumulation of the output results of each decision tree. Using the combination of gradient boosting and regression decision trees, each time a new decision tree model is established, it is in the direction of the gradient of the loss function of the previous model, so that the decision model is continuously improved. .
[0038] 1. Decision tree algorithm.
[0039] Decision tree algorithm is an important algorithm in machine learning and data mining. It is mainly used to deal with some problems under given rule conditions. Like most algorithm models, this algorithm can be used to classify and regress data, so as to establish an effective data model to deal with related probl...
Embodiment 2
[0066] Example 2 The clinical application of the myeloma risk prediction method based on the GBDT model.
[0067] The Medical Ethics Committee of Shengjing Hospital of China Medical University approved this study (2020PS055J) according to the principles of the Declaration of Helsinki. The ethics committee waived the requirement for individual informed consent when conducting a retrospective study of electronic medical records. 1. Screening of patients and data.
[0068] In this retrospective study, the institutional database of Shengjing Hospital of China Medical University was screened to investigate patients who underwent routine blood tests, liver function tests, renal function tests, and immunoglobulin tests for the first time in our hospital from January 2010 to January 2020. These included 1741 cases of multiple myeloma (MM) and 2446 cases of non-myeloma (infectious disease, rheumatic immune system disease, liver disease and kidney disease). The inventors also collecte...
