机器学习领域中分类方法和回归方法是相对的，大多数的方法可以相互转换，即一般的机器学习方法如果可以分类的话，也会可以做回归预测。在本例的回归方法中，使用的评价指标是RMSE。
第一步：导入数据库
import sys
from time import time
import pandas as pd
import matplotlib.pyplot as plt
from pyspark import SparkConf, SparkContext
from pyspark.mllib.tree import DecisionTree
from pyspark.mllib.regression import LabeledPoint
import numpy as np
from pyspark.mllib.evaluation import RegressionMetrics
import math
第二步：数据准备
def extract_label(record):
label=(record[-1])
return float(label)
def convert_float(x):
return (0 if x=="?" else float(x))
def extract_features(record,featureEnd):
featureSeason=[convert_float(field) for field in record[2]]
features=[convert_float(field) for field in record[4: featureEnd-2]]
return np.concatenate( (featureSeason, features))
def PrepareData(sc):
print("Data loading...")
rawDataWithHeader = sc.textFile(Path+"data/hour.csv")
header = rawDataWithHeader.first()
rawData = rawDataWithHeader.filter(lambda x:x !=header)
lines = rawData.map(lambda x: x.split(","))
print (lines.first())
print("The number of data:" + str(lines.count()))
labelpointRDD = lines.map(lambda r:LabeledPoint(
extract_label(r),
extract_features(r,len(r) - 1)))
print(labelpointRDD.first())
(trainData, validationData, testData) = labelpointRDD.randomSplit([8, 1, 1])
print("TrainData:" + str(trainData.count()) +
"ValidationData:" + str(validationData.count()) +
"TestData:" + str(testData.count()))
return (trainData, validationData, testData)
第三步：对模型进行训练
def PredictData(sc,model):
print("Data loading...")
rawDataWithHeader = sc.textFile(Path+"data/hour.csv")
header = rawDataWithHeader.first()
rawData = rawDataWithHeader.filter(lambda x:x !=header)
lines = rawData.map(lambda x: x.split(","))
print("The number of data:" + str(lines.count()))
labelpointRDD = lines.map(lambda r: LabeledPoint(
extract_label(r),
extract_features(r,len(r) - 1)))
SeasonDict = { 1 : "春", 2 : "夏", 3 :"秋", 4 : "冬" }
HoildayDict={ 0 : "非假日", 1 : "假日" }
WeekDict = {0:"一",1:"二",2:"三",3:"四",4 :"五",5:"六",6:"日"}
WorkDayDict={ 1 : "工作日", 0 : "非工作日" }
WeatherDict={ 1 : "晴", 2 : "阴", 3 : "小雨", 4 : "大雨" }
for lp in labelpointRDD.take(100):
predict = int(model.predict(lp.features))
label=lp.label
features=lp.features
result = ("True" if (label == predict) else "False")
error = math.fabs(label - predict)
dataDesc="Feature: "+SeasonDict[features[0]] +"季,"+
str(features[1]) + "月," +
str(features[2]) + "时,"+
HoildayDict[features[3]] +","+
"Week"+WeekDict[features[4]]+","+
WorkDayDict[features[5]]+","+
WeatherDict[features[6]]+","+
str(features[7] * 41)+ "度,"+
"Temperature" + str(features[8] * 50) + "度," +
"Humidity" + str(features[9] * 100) + ","+
"Wind speed" + str(features[10] * 67) +
"Predict result:" + str(predict )+
"Actual:" + str(label) + result +", Error:" + str(error)
print(dataDesc)
第四步：对模型进行评估
def evaluateModel(model, validationData):
score = model.predict(validationData.map(lambda p: p.features))
scoreAndLabels=score.zip(validationData.map(lambda p: p.label))
metrics = RegressionMetrics(scoreAndLabels)
RMSE=metrics.rootMeanSquaredError
return(RMSE)
def trainEvaluateModel(trainData,validationData,
impurityParm, maxDepthParm, maxBinsParm):
startTime = time()
model = DecisionTree.trainRegressor(trainData,
categoricalFeaturesInfo={},
impurity=impurityParm,
maxDepth=maxDepthParm,
maxBins=maxBinsParm)
RMSE = evaluateModel(model, validationData)
duration = time() - startTime
print (" impurityParm= %s"%impurityParm+
" maxDepthParm= %s"%maxDepthParm+
" maxBinsParm = %d."%maxBinsParm +
" Time=%d"%duration +
" RMSE = %f " % RMSE )
return (RMSE,duration, impurityParm, maxDepthParm, maxBinsParm,model)
def evalParameter(trainData, validationData, evaparm,impurityList, maxDepthList, maxBinsList):
metrics = [trainEvaluateModel(trainData, validationData, impurity,maxdepth, maxBins )
for impurity in impurityList
for maxdepth in maxDepthList
for maxBins in maxBinsList ]
if evaparm=="impurity":
IndexList=impurityList[:]
elif evaparm=="maxDepth":
IndexList=maxDepthList[:]
elif evaparm=="maxBins":
IndexList=maxBinsList[:]
df = pd.DataFrame(metrics,index=IndexList,
columns=['RMSE', 'duration','impurityParm', 'maxDepthParm', 'maxBinsParm','model'])
showchart(df,evaparm,'RMSE','duration',0,200 )
def showchart(df,evalparm ,barData,lineData,yMin,yMax):
ax = df[barData].plot(kind='bar', title =evalparm,figsize=(10,6),legend=True, fontsize=12)
ax.set_xlabel(evalparm,fontsize=12)
ax.set_ylim([yMin,yMax])
ax.set_ylabel(barData,fontsize=12)
ax2 = ax.twinx()
ax2.plot(df[[lineData ]].values, linestyle='-', marker='o', linewidth=2.0,color='r')
plt.show()
def evalAllParameter(training_RDD, validation_RDD, impurityList, maxDepthList, maxBinsList):
metrics = [trainEvaluateModel(trainData, validationData, impurity,maxdepth, maxBins )
for impurity in impurityList
for maxdepth in maxDepthList
for maxBins in maxBinsList ]
Smetrics = sorted(metrics, key=lambda k: k[0])
bestParameter=Smetrics[0]
print("impurity:" + str(bestParameter[2]) +
" ,maxDepth:" + str(bestParameter[3]) +
" ,maxBins:" + str(bestParameter[4]) +
" ,RMSE = " + str(bestParameter[0]))
return bestParameter[5]
def parametersEval(training_RDD, validation_RDD):
print("-----MaxDepth---------")
evalParameter(training_RDD, validation_RDD,"maxDepth",
impurityList=["variance"],
maxDepthList =[3, 5, 10, 15, 20, 25] ,
maxBinsList=[10])
print("----MaxBins---------")
evalParameter(training_RDD, validation_RDD,"maxBins",
impurityList=["variance"],
maxDepthList=[10],
maxBinsList=[3, 5, 10, 50, 100, 200 ])
第五步：Spark相关设置
def SetLogger( sc ):
logger = sc._jvm.org.apache.log4j
logger.LogManager.getLogger("org"). setLevel( logger.Level.ERROR )
logger.LogManager.getLogger("akka").setLevel( logger.Level.ERROR )
logger.LogManager.getRootLogger().setLevel(logger.Level.ERROR)
def SetPath(sc):
global Path
if sc.master[0:5]=="local" :
Path="file:/home/jorlinlee/pythonsparkexample/PythonProject/"
else:
Path="hdfs://master:9000/user/jorlinlee/"
def CreateSparkContext():
sparkConf = SparkConf()
.setAppName("RunDecisionTreeRegression")
.set("spark.ui.showConsoleProgress", "false")
sc = SparkContext(conf = sparkConf)
print ("master="+sc.master)
SetLogger(sc)
SetPath(sc)
return (sc)
sc.stop()
第六步：运行主程序
if __name__ == "__main__":
print("RunDecisionTreeRegression")
sc=CreateSparkContext()
print("Preparing")
(trainData, validationData, testData) =PrepareData(sc)
trainData.persist(); validationData.persist(); testData.persist()
print("Testing")
(AUC,duration, impurityParm, maxDepthParm, maxBinsParm,model)=
trainEvaluateModel(trainData, validationData, "variance", 10, 100)
if (len(sys.argv) == 2) and (sys.argv[1]=="-e"):
parametersEval(trainData, validationData)
elif (len(sys.argv) == 2) and (sys.argv[1]=="-a"):
print("Best parameters")
model=evalAllParameter(trainData, validationData,
["variance"],
[3, 5, 10, 15, 20, 25],
[3, 5, 10, 50, 100, 200 ])
print("Testing")
RMSE = evaluateModel(model, testData)
print("RMSE:" + str(RMSE))
print("Predict")
PredictData(sc, model)
