构造哈夫曼树 哈弗曼树中没有度为一的节点，是标准的二叉树，所以有n个叶子结点时，需要一个长度为2n-1的一维数组存储哈弗曼树的结点。 (1)、n个叶子节点只有weight权值，处理非叶子节点，从ht[i]（ht[1]~ht[n-1]）中找到ht[i].weight最小的两个节点ht[s1]和ht[s2]，这就是Select(int n,int &s1,int & s2,HTNode *ht)函数完 ...

学上的基本神经元，人工的神经网络也有基本的神经元。每个神经元有特定数量的输入，也会为每个神经元设定权重（weight）。权重是对所输入的资料的重要性的一个指标。然后，神经元会计算出权重合计值（net value），而权重合计值就是将所有输入乘以它们的权重的合计。每个神经元都有它们各自的临界值（threshold），而当权重 ...
