我有一个模型,我试图计算加权平均值:
public class ObScore
{
public int ObScoreId { get; set; }
public int AnalystId { get; set; }
public DateTime Date { get; set; }
public int PossScore { get; set; }
public int Weight { get; set; }
}
我可以这样做,使用以下代码:
//
// GET: /Test/
public Actio
我在Visual Basic 2010中编写了以下用于计算加权平均值的通用LINQ扩展:
<Extension()>
Function WeightedAverage(Of T)(ByVal source As IEnumerable(Of T),
ByVal selectorValue As Func(Of T, Integer),
ByVal selectorWeight As Func(Of T, Integer)) As Double
Dim weightedValueSum As Double
Dim wei
我在Python中有一个带有加权边的networkx图。我想得到两个节点之间最小路径的权重。
目前,我正在从nx.shortest_path实现中获取最短路径中的节点,然后迭代每一对节点,并对每一对节点之间的权重进行求和。
shortest_path = nx.shortest_path(G, source, destination, 'distance')
#function to iterate over each pair
import itertools
def pairwise(iterable):
a, b = itertools.tee(iterabl
我目前正在尝试(努力)在elki中实现一个WeightedCorePredicate来实现trying _ implement。修改后的核心谓词代码如下所示: public boolean isCorePoint(DBIDRef point, DBIDs neighbors) {
WeightSum = 0.0; // Make sure to initialize the weights as 0
for (DBIDIter it = neighbors.iter(); it.valid(); it.advance()) {
/*
我正在以编程方式在LinearLayout中创建RelativeLayout。我要做的是在LinearLayout中分配LinearLayout中的layout_above,同时也要设置layout_above属性。问题是weightSum在LinearLayout.LayoutParams中可用,layout_above在RelativeLayout.LayoutParams中可用。目前,我正在做
LinearLayout ll_menu_code = new LinearLayout(this);
ll_menu_code.setId(1001);

我很难理解如何在两个线程上同步ArrayList。基本上,我希望一个线程将对象追加到列表中,另一个线程同时从该列表中读取对象。
下面是部署线程的类:
public class Main {
public static ArrayList<Good> goodList = new ArrayList();
public static void main(String[] args) {
Thread thread1 = new Thread(new GoodCreator());
Thread thread2 = new Thread(
