【摘要】：為確定某型飛機(jī)燃油消耗量同其它因素之間的相關(guān)關(guān)系,首先將預(yù)處理后的某場(chǎng)站近三年燃料油消耗的實(shí)際數(shù)據(jù)隨機(jī)地分成10份;然后,分別借助決策樹和隨機(jī)森林算法,對(duì)數(shù)據(jù)建立回歸模型,并采用10折交叉驗(yàn)證法,判斷上述結(jié)果的可靠性;最后,使用平均的標(biāo)準(zhǔn)化均方誤差來評(píng)價(jià)模型,得出結(jié)論.
[Abstract]:In order to determine the correlation between fuel consumption and other factors of a certain aircraft, the actual data of fuel oil consumption of a pretreated station in the past three years were randomly divided into 10 parts, and then, with the help of decision tree and stochastic forest algorithm, The regression model is established and the reliability of the above results is judged by using the 10 fold cross validation method. Finally, the model is evaluated with the average standardized mean square error, and the conclusion is drawn.
