PSOSVR模型的構(gòu)建過程如下:初始化粒子群,每個(gè)粒子代表SVR的一組參數(shù)組合;然后,根據(jù)適應(yīng)度函數(shù)(通常采用均方誤差MSE作為評(píng)價(jià)標(biāo)準(zhǔn))評(píng)估每個(gè)粒子的優(yōu)劣;接著,通過個(gè)體極值和全局極值的更新,引導(dǎo)粒子群向更優(yōu)的解空間搜索;當(dāng)滿足終止條件(如達(dá)到最大迭代次數(shù)或解的變化小于預(yù)設(shè)閾值)時(shí),輸出最優(yōu)參數(shù)組合,并以此構(gòu)建SVR模型進(jìn)行滑坡位移的預(yù)測(cè)。Specifically,theconstructionprocessofthePSOSVRmodelisasfollows:initializetheparticleswarm,whereeachparticlerepresentsasetofparametercombinationsforSVR;Then,evaluatethequalityofeachparticlebasedonthefitnessfunction(usuallyusingmeansquarederror(MSE)astheevaluationcriterion);Next,byupdatingindividualandglobalextrema,theparticleswarmisguidedtosearchforamoreoptimalsolutionspace;Whentheterminationconditionismet(suchasreachingthemaximumnumberofiterationsorthechangeinthesolutionislessthanthepresetthreshold),theoptimalparametercombinationisoutput,andanSVRmodelisconstructedbasedonthistopredictlandslidedisplacement.PSOSVR模型結(jié)合了PSO的全局搜索能力和SVR的非線性映射能力,既能夠避免SVR參數(shù)選擇的盲目性,又能夠充分利用樣本數(shù)據(jù)的信息,提高預(yù)測(cè)精度和穩(wěn)定性。因此,本文選擇PSOSVR模型作為白水河滑坡位移預(yù)測(cè)的主要方法。在接下來的研究中,我們將詳細(xì)闡述PSOSVR模型的具體實(shí)現(xiàn)過程,并通過實(shí)驗(yàn)驗(yàn)證其在白水河滑坡位移預(yù)測(cè)中的有效性。ThePSOSVRmodelcombinestheglobalsearchabilityofPSOandthenonlinearmappingabilityofSVR,whichcanavoidtheblindnessofSVRparameterselectionandfullyutilizetheinformationofsampledatatoimprovepredictionaccuracyandstability.Therefore,thisarticlechoosesthePSOSVRmodelasthemainmethodforpredictingthedisplacementoftheBaishuiRiverlandslide.Inthefollowingresearch,wewillelaborateonthespecificimplementationprocessofthePSOSVRmodelandverifyitseffectivenessinpredictingthedisplacementoftheBaishuiRiverlandslidethroughexperiments.五、基于時(shí)間序列與PSOSVR耦合模型的滑坡位移預(yù)測(cè)LandslidedisplacementpredictionbasedontimeseriesandPSOSVRcoupledmodel滑坡位移預(yù)測(cè)是滑坡災(zāi)害防治和預(yù)警的重要環(huán)節(jié),對(duì)于減少災(zāi)害損失、保障人民生命財(cái)產(chǎn)安全具有重要意義。本研究采用時(shí)間序列分析與PSOSVR(粒子群優(yōu)化支持向量回歸)耦合模型,對(duì)白水河滑坡的位移進(jìn)行預(yù)測(cè)研究。Landslidedisplacementpredictionisanimportantpartoflandslidedisasterpreventionandearlywarning,whichisofgreatsignificanceforreducingdisasterlossesandensuringthesafetyofpeople'slivesandproperty.ThisstudyusesatimeseriesanalysisandPSOSVR(ParticleSwarmOptimizationSupportVectorRegression)coupledmodeltopredictthedisplacementoftheBaishuiRiverlandslide.我們收集白水河滑坡的歷史位移數(shù)據(jù),這些數(shù)據(jù)呈現(xiàn)出明顯的時(shí)間序列特征。通過時(shí)間序列分析,我們提取了滑坡位移的主要趨勢(shì)和周期性變化,為后續(xù)的模型建立提供了數(shù)據(jù)基礎(chǔ)。WecollectedhistoricaldisplacementdataoftheBaishuiRiverlandslide,whichexhibitedobvioustimeseriescharacteristics.Throughtimeseriesanalysis,weextractedthemaintrendsandperiodicchangesoflandslidedisplacement,providingadatafoundationforsubsequentmodelestablishment.然后,我們構(gòu)建了基于PSOSVR的滑坡位移預(yù)測(cè)模型。該模型利用粒子群優(yōu)化算法(ParticleSwarmOptimization,PSO)對(duì)支持向量回歸(SupportVectorRegression,SVR)模型的參數(shù)進(jìn)行優(yōu)化,以提高預(yù)測(cè)精度和泛化能力。PSO算法通過模擬鳥群捕食行為,實(shí)現(xiàn)了對(duì)SVR模型參數(shù)的高效搜索和優(yōu)化。Then,weconstructedalandslidedisplacementpredictionmodelbasedonPSOSVR.ThismodelutilizesParticleSwarmOptimization(PSO)algorithmtooptimizetheparametersofSupportVectorRegression(SVR)model,inordertoimprovepredictionaccuracyandgeneralizationability.ThePSOalgorithmefficientlysearchesandoptimizestheparametersoftheSVRmodelbysimulatingthepredatorybehaviorofbirdflocks.在模型建立過程中,我們采用了交叉驗(yàn)證的方法對(duì)模型進(jìn)行訓(xùn)練和驗(yàn)證,以確保模型的穩(wěn)定性和泛化能力。同時(shí),我們還對(duì)模型的預(yù)測(cè)結(jié)果進(jìn)行了誤差分析,包括均方誤差(MeanSquaredError,MSE)、均方根誤差(RootMeanSquaredError,RMSE)等指標(biāo)的計(jì)算和比較。Duringthemodelbuildingprocess,weusedcrossvalidationtotrainandvalidatethemodeltoensureitsstabilityandgeneralizationability.Atthesametime,wealsoconductederroranalysisonthepredictionresultsofthemodel,includingthecalculationandcomparisonofindicatorssuchasMeanSquaredError(MSE)andRootMeanSquaredError(RMSE).最終,我們得到了基于時(shí)間序列與PSOSVR耦合模型的滑坡位移預(yù)測(cè)結(jié)果。預(yù)測(cè)結(jié)果表明,該模型能夠較好地?cái)M合歷史數(shù)據(jù),并對(duì)未來的滑坡位移進(jìn)行較為準(zhǔn)確的預(yù)測(cè)。這為白水河滑坡的災(zāi)害防治和預(yù)警提供了有力的技術(shù)支撐。Finally,weobtainedthelandslidedisplacementpredictionresultsbasedonthecouplingmodeloftimeseriesandPSOSVR.Thepredictionresultsindicatethatthemodelcanfithistoricaldatawellandaccuratelypredictfuturelandslidedisplacement.ThisprovidesstrongtechnicalsupportforthedisasterpreventionandearlywarningoftheBaishuiRiverlandslide.基于時(shí)間序列與PSOSVR耦合模型的滑坡位移預(yù)測(cè)方法具有較高的預(yù)測(cè)精度和泛化能力,為滑坡災(zāi)害防治和預(yù)警提供了新的有效途徑。未來的研究可以進(jìn)一步優(yōu)化模型參數(shù)和算法,提高預(yù)測(cè)精度和穩(wěn)定性,為滑坡災(zāi)害防治提供更加可靠的技術(shù)支持。ThelandslidedisplacementpredictionmethodbasedonthecouplingmodeloftimeseriesandPSOSVRhashighpredictionaccuracyandgeneralizationability,providinganewandeffectivewayforlandslidedisasterpreventionandearlywarning.Futureresearchcanfurtheroptimizemodelparametersandalgorithms,improvepredictionaccuracyandstability,andprovidemorereliabletechnicalsupportforlandslidedisasterpreventionandcontrol.六、實(shí)驗(yàn)結(jié)果與分析Experimentalresultsandanalysis本研究采用了時(shí)間序列分析與粒子群優(yōu)化支持向量回歸(PSOSVR)耦合模型對(duì)白水河滑坡的位移進(jìn)行了預(yù)
