摘 要:Data pricing is a key link to promote the efficient circulation of data in the market.However,the existing methods are still insufficient in terms of pertinence,dynamism and comprehensiveness.Therefore,we proposed a data pricing prediction model based on sparrow search optimization XGBoost,aiming to provide a reference for pricing decisions in data market.First,we crawled the data transaction information of Youedata.com and performed preprocessing operations such as outlier processing,one hot encoding and logarithmic transformation on the dataset;Secondly,we conducted exploratory data analysis to understand the distribution of data and their correlation.Then,we used the LASSO algorithm to select features for the dataset and constructed a data pricing prediction model based on SSA-XGBoost.Finally,we compared and analyzed it with six machine learning models including LightGBM,GBDT,MLP,KNN,LR and XGBoost.The experimental results show that in terms of the R-squared,the prediction results of the proposed SSA-XGBoost model exceed the above six models by 4.9%,7.4%,7.1%,23.8%,12.8%,and 2.3%respectively,and are superior to the state-of-the-art work.Furthermore,the evaluation results of the five indicators of MSE,RMSE,MAE,MAPE,and RMSPE are better than other models,showing higher stability.
