如何使画布透明？我需要因为我想把两幅画布放在一起.

我试图用C#中的高斯朴素贝叶斯来实现点的分类.我已经实现了第一部分(http://www.statsoft.com/textbook/naive-bayes-classifier/)概率部分,但我不明白如何实现高斯朴素贝叶斯算法的正态模型.这是我的代码:

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++)
            { …

我对php中的语法有疑问.以下行中+的平均值是多少？谢谢!

+$array['key1']['key2'] = "value"

我想做一个从文本中检测情绪的应用程序.要做到这一点,我需要一个本体论.我的问题是,如果你知道一个可以帮助我的现存本体论.
