EmdL1_v2
- 这是一个对于L2范数下的Earth Mover Distance的VC实现。
chi_square_distance
- C++ and Matlab work togather to compute the distance between to sets of vectors or matrix (chi-suare, X2, L2 and etc.)
code
- 独立主成分分析与主成分分析代码，速度比较快，而且比较好用-In these first experiments, both ICA and whitened PCA are used to compress the data, and all the components are used for classifying the examples. The classifier used is a 1-NN with Euclidean distance. The results shown i

HUFFMAN-CODING-TREE.cpp
- 构造一个具有n个外部节点的扩充二叉树，每个外部节点Ki有一个Wi对应，作为该外部节点的权。使得这个扩充二叉树的叶节点带权外部路径长度总和最小： Min( W1 * L1 + W2 * L2 + W3 * L3 + … + Wn * Ln) Wi:每个节点的权值。 Li:根节点到第i个外部叶子节点的距离。 编程计算最小外部路径长度总和。-Constructing a binary tree with n external expansion nodes, each external n
fuzzy
- Fuzzy c-means clustering (FCM) with spatial constraints (FCM_S) is an effective algorithm suitable for image segmentation. Its effectiveness contributes not only to introduction of fuzziness for belongingness of each pixel but also to exploitat
CalcCrowdingDistance
- In mathematics, the Euclidean distance or Euclidean metric is the ordinary (i.e. straight-line) distance between two points in Euclidean space. With this distance, Euclidean space becomes a metric space. The associated norm is called the Euclidean no
