Gaussian Naive Bayesを実装する

Question

私は、点の分類のためにC＃でガウスのNaive Bayesを実装しようとしています。私は の最初の部分（http://www.statsoft.com/textbook/naive-bayes-classifier/）の確率部分を実装しているが、私はガウスのNaive Bayesアルゴリズムのノーマルモデルを実装する方法を理解していない。 これは私のコードです：このPDFファイルに

class NaiveBayesClassifier 
    { 
     private List<Point> listTrainPoints = new List<Point>(); 
     private int totalPoints = 0; 

     public NaiveBayesClassifier(List<Point> listTrainPoints) 
     { 
      this.listTrainPoints = listTrainPoints; 
      this.totalPoints = this.listTrainPoints.Count; 
     } 

     private List<Point> vecinityPoints(Point p, double maxDist) 
     { 
      List<Point> listVecinityPoints = new List<Point>(); 
      for (int i = 0; i < listTrainPoints.Count; i++) 
      { 
       if (p.distance(listTrainPoints[i]) <= maxDist) 
       { 
        listVecinityPoints.Add(listTrainPoints[i]); 
       } 
      } 
      return listVecinityPoints; 
     } 

     public double priorProbabilityFor(double currentType) 
     { 
      double countCurrentType = 0; 
      for (int i = 0; i < this.listTrainPoints.Count; i++) 
      { 
       if (this.listTrainPoints[i].Type == currentType) 
       { 
        countCurrentType++; 
       } 
      } 

      return (countCurrentType/this.totalPoints); 
     } 

     public double likelihoodOfXGiven(double currentType, List<Point> listVecinityPoints) 
     { 
      double countCurrentType = 0; 
      for (int i = 0; i < listVecinityPoints.Count; i++) 
      { 
       if (listVecinityPoints[i].Type == currentType) 
       { 
        countCurrentType++; 
       } 
      } 

      return (countCurrentType/this.totalPoints); 
     } 

     public double posteriorProbabilityXBeing(double priorProbabilityFor, double likelihoodOfXGiven) 
     { 
      return (priorProbabilityFor * likelihoodOfXGiven); 
     } 

     public int allegedClass(Point p, double maxDist) 
     { 
      int type1 = 1, type2 = 2; 

      List<Point> listVecinityPoints = this.vecinityPoints(p, maxDist); 

      double priorProbabilityForType1 = this.priorProbabilityFor(type1); 
      double priorProbabilityForType2 = this.priorProbabilityFor(type2); 

      double likelihoodOfXGivenType1 = likelihoodOfXGiven(type1, listVecinityPoints); 
      double likelihoodOfXGivenType2 = likelihoodOfXGiven(type2, listVecinityPoints); 

      double posteriorProbabilityXBeingType1 = posteriorProbabilityXBeing(priorProbabilityForType1, likelihoodOfXGivenType1); 
      double posteriorProbabilityXBeingType2 = posteriorProbabilityXBeing(priorProbabilityForType2, likelihoodOfXGivenType2); 

      if (posteriorProbabilityXBeingType1 > posteriorProbabilityXBeingType2) 
       return type1; 
      else 
       return type2; 
     } 
    } 

（問題5）私は（http://romanager.ro/s.10-701.hw1.sol.pdf）を行うために必要なものの記述があります。私の仕事は、Gaussina Naive BayesとkNNアルゴリズムを実装し、その結果を一連のデータと比較することです。 Gaussian Naive Bayesアルゴリズムを実装する場所と方法を教えてください。

ありがとうございます！
