采用ESP8226芯片设计一款物联网简易实验箱,并将实验箱应用到本科的物联网和电子专业实践教学中,让学生能够学习到电路设计、硬件驱动编程和上层APP编程,熟悉物联网系统开发.学生可以在这个物联网开发板上设计创新实验,制作物联网作品.
针对计算机类学生入门级程序设计课程的教学,文章提出以"计算思维"为导向,分模块教学的方法,注重"计算思维"疏导,按计算机解决问题的步骤,分模块依次进行教学.辅以简单的程序设计案例,以数学思维和计算思维两种方式相融合进行解题,以此来提高学生对数学思维和计算思维的认知,并迅速完成数学思维到计算思维的转变与形成.
本文针对独立学院学生的学习特点,利用计算机应用技术开发的一个基于问答数量与权值统计的APP移动应用系统,以"移动应用与技术"专业课程授课为例,进行了基于问答数量和权值统计的教学研究.通过该教学方法提高了学生自主学习的能力,取得了较好的教学效果.
It supposes that the search results bear some relation both to the Key words:of the query and a certain text category.As such,queries are constructed according to the feature words extracted from the initial sample set,then queries are send to the search engine and web pages are downloaded from the search results which response from the search engine.Downloaded web pages are processed by eliminating of duplicated content,noise reduction and extraction of text content.These samples are expanded into the sample set after the category of the samples is predicted.Finally a Naive Bayes text classifier is retrained by the enlarged sample set.The classification effect of the classifier is also experimented.Experimental results show that the precision of semi-supervised text classification method with information retrieval techniques is significantly better than the classifier constructed by small sample set.
Visual FoxPro(简称"VFP")课程是计算机文化基础的一个重要组成部分,也是NCRE二级的一个可选科目,本文从云南大学旅游文化学院的VFP课程和该校学生特点入手,在教法方面总结了一些有益的思路和建议,并将其应用到实际的VFP课程的教学与考试中,通过两个学期的改革以及对数据的收集对比,表明该改革有效地调动学生的学习积极性,提高了学生对VFP课程的掌握度。
According to research of client honey-pot system and mechanism of the malicious web sites attacks,a highly interactive client honey-pot system called Malicious Web Site Hunter was designed and implemented based on Agent working model.The system is composed of control sub-system,high-interaction client honey pot sub-system and service sub-system.It is a malicious websites detecting with intelligence,which make full use of Agent's cooperation and honey pot's accuracy.The formal description of Agent of the system is implemented based on Agent VSK Logic formal description language,which not only to describe the Agent and its characteristics of environmental information,but also can describe the complete state of change process.
Web spam detection becomes a hot topic in the field of machine learning in.Based on the introduction of search engine spam and spam techniques,this paper makes a review of research on various Web spam detection models.For a variety of models,especially as the content analysis based detection model,link structures based detection models,detection model combined content and link structures,and others,are described and analyzed.The direction of the research on the topic is also conducted to the prospect.
