本文主要分析了CUDA加速KNN算法满足的条件,阐述了KNN程序算法的核心思想,并针对KNN算法的性能进行了研究和探讨,以期通过改进KNN算法,来提高人们的使用效果.

0 引言 VB程序设计即Visual Basic程序设计的简称,具备简单、便捷、实用等特点,因此,其应用范围较广,支持各类软件的开发、设计.尤其是在1991年问世之后,其深得Windows开发人员的厚爱,其推广速度之快、范围之广让人惊叹.至今,VB作为成熟的程序设计语言,已然成为当今最受欢迎、应用最为广泛的语言之一.

针对传统k-means算法中初始聚类中心选取的随意性对于聚类结果影响较大的问题,提出了基于Leader算法的k-means改进算法——Lk-means算法.该算法有效避免了初始聚类中心选取的边缘化和随意性.实验证明,Lk-means算法的聚类结果更加有效合理.

Based on the fact that the students in vocational college generally have the poor study foundation,little interest in study and poor self-learning ability,this paper proposed that the step-by-step method in the VB programming design course could guide the students to acquire the knowledge step by step better,and generate their sense of achievement so as to improve their interest towards study.The real case study proves that this teaching method reaches a better effect in class.

Describes how to build the teaching mode based on working process-oriented,working cases as carrier,completing the tasks for teaching objectives,so as to enhance the learning interesting,cultivate the professional competence of students.

This article has carried on the network teaching and the tradition classroom instruction method by the contrast analysis, had pointed out the network teaching superiority, has analyzed the vital significance of the network teaching in the school, had pointed out several questions which the network teaching urgent needs to pay attention at present, finally proposes that only use the superiority of the network teaching fully, simultaneously also carries on the nimble improvement to the traditional classroom instruction method, enhances strong points and avoid weaknesses, can raise the teaching level well and improve the quality of teaching.
