摘要
针对影响混凝土抗压强度的多种主要因素,采用迭代决策树方法构建了预测模型,并以28 d抗压强度作为研究对象。通过迭代决策树原理分析与实验测试进行了模型验证。结果表明,迭代决策树模型在混凝土抗压强度预测中具有很好的应用价值以及更理想的预测结果。
The main factors that affect the compressive strength of concrete.A gradient boosting decision tree method is used to construct the prediction model,and the 28 days of compressive strength as the research object.Through the gradient boosting decision tree principle analysis and experimental test model verification.The results show that the model based on gradient boosting decision tree has good application value and better prediction results in concrete compressive strength prediction.
