Hello, Prof. Philippe Fournier-Viger.
For the past 2 years, during the implementation of the final project of the master's course, I have been asking you questions and you have answered them very well. Thank you for your guidance. next. I am again interested in implementing one of the plans I have in mind
I want to implement an algorithm that works like a hui-miner, based on list (utility-li Forum: The Data Mining / Big Data Forum
"If it is easy to combine, then it is not interesting..."
That's exactly the same. You are the best professor. I am not fluent in English, And I can not really convey my sense!
Thank you very much for your complete description. Now I am studying several other papers. I hope to give you some good news from this topic Forum: The Data Mining / Big Data Forum
Hello, Prof. Philippe Fournier-Viger.
I'm a master's degree student and for final project , I'm researching on "Top-k high utility itemsets mining". During this period of study, I had studies in the field of data mining and implemented in C#, such as Two-phase, Hui-miner, La prune, Efim, TKEH, kHMC ,...
Now I'm looking for a new idea for top-k mining. I'm having trouble at this st Forum: The Data Mining / Big Data Forum
Dear Professor ,
I would like to Implementation TKEH Algorithm. I have encountered some problems such as COV strategy and EUCS.
Is the implementation of this article available to you?
Can you provide implementation of the kHMC algorithm?
Can you give me some useful tips?
Your assist will lighten this way for me to find the best solution for my questions, which will always push me to rem Forum: The Data Mining / Big Data Forum
Thank you for your attention, Yes, I'll definitely be looking for spmf.
But just one question of "get the initial population P with the proposed problem-specific initialize strategy" :
What is the concept of the following sentence?

Yes, I tried, but I did not get an answer during this time. Is it possible to provide just a numerical example of the MOEA/FHUI algorithm? Please

Hi, Is there a documentation and java source code for this article?
Title: A Multi-Objective Evolutionary Approach for Mining Frequent and High Utility Itemsets

thanks, best regards Forum: The Data Mining / Big Data Forum
So which items can I combine together?
for dfgb
d,f,g | f,g,b (two different , d and b)
d,f,g | d,g,b (two different , f and b)
d,f,g | d,f,b (two different , b and g)
d,f,b | f,g,b (two different , d and g) Forum: The Data Mining / Big Data Forum
Hi. I was coding the hui-miner ( Mining High Utility Itemsets without Candidate Generation ) in C#, which I encountered a problem.
There is no problem in 1-itemset and 2-itemset items. but in k-itemset, for example :
To create "dfgb" :
u({dfgb}, Each transaction) = u({dfg}, Each transaction) + u({fgb}, Each transaction) - u({fg}, Each transaction)
It has no problems programmin Forum: The Data Mining / Big Data Forum
I intend to implement the algorithm two phase (spmf) in C#. In the article, there is no semicode. You can tell it' semicode? Forum: The Data Mining / Big Data Forum
