此示例演示如何训练随机树分类推进分类器，或MLP，或Knearest，或Nbayes，或支持向量机-This example demonstrates how classified propulsion classifier training random tree, or the MLP, Knearest, or Nbayes or support vector machines

its a machine learning programme which uses k nearest neighbor algorithm, find the distances between the k features point and plots the graph.
