Eclipse can run JUnit tests, there is plenty of documentation available such as <a href="http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2FgettingStarted%2Fqs-junit.htm" rel="Sujit Palhttps://www.blogger.com/profile/06835223352394332155noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-37043270945709435612015-01-24T07:52:03.855-08:002015-01-24T07:52:03.855-08:00please help me ,I work on genetic algorithm ,I sho...please help me ,I work on genetic algorithm ,I show your code and it is helpful for me but how your code is run in eclipse.please reply fast as soon as possible <br /> Thank you,<br /> aarti Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7583720.post-40659018960764526522012-07-11T08:09:35.897-07:002012-07-11T08:09:35.897-07:00Hi hannister, if you download the code in jtmt.sf....Hi hannister, if you download the code in jtmt.sf.net you should have all the necessary classes to run the JUnit test which will dump out the cluster coordinates and you then use gnuplot to draw the charts.<br /><br />The only difference between your approach and mine is that your data is in Lucene. To run KMeans using my code, you will have to convert the data into a TD Matrix (a 2D matrix with Sujit Palhttps://www.blogger.com/profile/06835223352394332155noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-55230202578368379492012-06-30T18:06:46.903-07:002012-06-30T18:06:46.903-07:00Hi Sujit.

I don't know which codes that you have here that I can use.. I really would like you to show me.. thanks.hanissterhttps://www.blogger.com/profile/14189559333502001486noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-25069553821749679742010-03-07T17:40:53.012-08:002010-03-07T17:40:53.012-08:00Hi lkhwan, yes, I think once you have done the SVD...Hi lkhwan, yes, I think once you have done the SVD on the TD matrix, you would have to compute the similarity between the document columns.Sujit Palhttps://www.blogger.com/profile/06835223352394332155noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-63863391036895898782010-03-05T15:24:04.919-08:002010-03-05T15:24:04.919-08:00Hi,

In the end, I want to visualize the cluster of documents. <br /><br />Suppose I get the LSI matrix already, what should I do to graph this matrix? Do I need to compute the similarity between document and do clustering manually? or I just take two matrices from SVD computation and visualize it.<br />Ikhwannoreply@blogger.comtag:blogger.com,1999:blog-7583720.post-83842449356031972542009-08-07T10:17:06.783-07:002009-08-07T10:17:06.783-07:00Hi, thanks, and yes, each column of the input 2-di...Hi, thanks, and yes, each column of the input 2-dimensional matrix corresponds to a single document in my collection.Sujit Palhttps://www.blogger.com/profile/06835223352394332155noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-41438292896905620062009-08-04T15:45:34.900-07:002009-08-04T15:45:34.900-07:00Hi!
