Hi Dvijesh & Baxter I also tried a few times to obtain the source code or implementations from some authors. I have never received a positive answer. I think that they should at least answer e-mails to say no. Yes, it takes time to implement algorithms again especially for complicated algorithms... By the way, Dvijesh, I did not forget to write to you about the bi-matrix. But I was t

Hello, For those who have trouble to see the relationship between the various data mining techniques, there is a visual classification of data mining techniques on this website (http://chem-eng.utoronto.ca/~datamining/dmc/data_mining_map.htm ). Of course, it is not perfect. But it is interesting. Note that on the website, you can click on the pictures to get a description of the tec

I did not find this information They probably use some kind of formula that consider the citation count, the number of papers published and maybe also some other criteria. It seems to be automatically generated. But I think that this list is good. I mostly agree with the top 6. SIAM, KDD and ICDM are top conferences.

Hello, I want to share an interesting article: "The Need for Open Source Software in Machine Learning" http://jmlr.csail.mit.edu/papers/volume8/sonnenburg07a/sonnenburg07a.pdf It is about why researchers should share the source code of their algorithms with other researchers.

This error is because the class MainTestPrefixSpan for testing PrefixSpan is located in ca/pfv/spmf/tests/ . If you run the code from the commnand line, you need to keep the package hierarchy otherwise it will not work. Or you need to modify the code to not use the package hierarchy. But it is more convenient to execute the code from a development environment because there is many classes and comp

Hello Dvijesh, Thanks for your feedback! Could you try running the class ca.pfv.spmf.gui.MainWindow in the source code version of SPMF? This is another way to launch the GUI. Maybe it would show you some error in the console and you could paste it to me so that I can see what is the problem. Also, could you tell me which operating system and Java version you are using? Also, maybe

Hello, The error "please check parameters" for PrefixSpan refers to the "minsup" parameter. For the minsup parameter, you need to write a value like this: 0.5 It means 50 %. But depending on your regional settings on your computer, you may have to write 0,5 with a , instead of a . This should solve the problem. Hope this helps, Philippe

Happy to know that your project is going well. Thanks for the comments. My current plan is to show only the statistics about the algorithm in the textbox (running time, number of patterns found, number of candidates generated, memory used, ...) and to save the list of patterns found to the output file (to avoid keeping the patterns into memory).

Hello Dvijesh, I did not try the generator, but according to the instructions in the README file, it says: Each line contains a sequence. The first number is the total number of itemsets in this sequence. After that, each itemset is displayed, first by the number of items in this itemset, then followed by the items in that itemset, in increasing order. Maybe you have read this already.

Thanks Dvijesh. :-) Here is what the GUI currently looks like: It is very simple. On the top there is a list to select an algorithm (e.g. FPGrowth). After that, the user has to choose the input file and the output file. Then, depending on the algorithm, the user has to fill some parameters (e.g. minsup and minconf). After that, the user click "Run algorithm" to run the alg
