代码说明:

说明:  直线偏移代码,已知多边形顶点坐标,可以将多边形各边沿其法线方向平移距离然后得到新的多边形顶点。(Linear shift code, known polygon vertex coordinates, can be the edge of the polygon shift its normal direction and then get a new polygon from the vertex.)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • K-meanCluster
    How the K-mean Cluster work Step 1. Begin with a decision the value of k = number of clusters Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following: Take the first k training sample as single-element clusters Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster. Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample. Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments. (How the K-mean Cluster workStep 1.
