Hello djanahana, I'm sorry for the late reply. Normally, I answer more quickly. But I was busy this week. To answer your question: List childNodes = new ArrayList<ITNode>(); It means that we create a list of ITNodes. If you don't write <ITNode> it would also works. But the compiler would not know that this list contains ITNode objects and you would need to always use a &

Hello, This is to let you know that I have updated the SPMF framework to add an association rule hiding algorithm named FHSAR. The goal of this algorithm is to hide some sensitive association rules that appear in a database. For example, consider that the rule 5 -->2 appears in a database with minsup = 50% and minconf = 50%. We can apply the FHSAR algorithm. It takes as input (1) a

Hello, This is to let you know that I have updated the SPMF framework for data mining. The new version includes an implementation of the algorithm for mining indirect association rules by Tan et al (2000) also described in the book by Tan, Steinbach and Kumar (2006). This algorithm allows to discover pairs of items that are indirectly associated together through another set of items called t

Hello Xin, I think that you can just assign a unique number for each function names. For example if you have some code like this: void functionA(){ int a, b = 5; int c = 6; functionA(a); functionB() functionC() functionD() } You could convert this to a transaction like this: 1 2 3 4 where : 1 = functionA, 2 = functionB, 3 = function
Forum: The Data Mining / Big Data Forum

Hello Xin, I think that you first need to determine what is your goal. I mean that you should think about what kind of patterns you want to discover and for which purpose? Setting your goal should help you to choose an appropriate algorithm. If you decide to use association rule mining, then you need to convert the source code in a transaction database. If you decide to use sequential pa

Hello everyone, I have read a good introductory data mining book lately. It is "Introduction to data mining" (2006) by Tan, Steinbach & Kumar ( http://www-users.cs.umn.edu/~kumar/dmbook/ ). This book is pretty easy to understand. It does not cover a wide range of topic unlike the book of Han & Kamber. But it provides a very good introduction to association rule mining,

I did not find any implementation of these algorithms either on the web. It seems like the persons who implemented them do not want to share the source code or even the executable files. I think that perhaps you could contact the authors of these algorithms to try to get the source code/executables, or contact some authors of articles that have used them, to ask them if they can share them w

Hello, This is to announce that I have made a Java implementation of the SPAM algorithm for sequential pattern mining.

Hello Mahnaz, The implementation of Taku Kudo is to my knowledge the only source code of PrefixSpan in C++. Jian pei et al. (the authors of PrefixSpan) offers a binary c++ implementation of PrefixSpan as part of the Illimine project. But they don't give the source code.

Hello, FP-Growth is a little bit complicated to explain. The best way to understand it is to take the time to read the paper. You can even draw some fp-trees on paper to make sure that you understand how it works. But I can give you a brief description of the main process. FPGrowth takes as input a transaction database. It outputs all the frequent itemsets (itemsets that appear in at least
