Hi, That is an interesting problem. In SPMF, there are some algorithms that deals with timestamps like Hirate and Yamana but it is very strict with how it handles the timestamp and it is likely not what you want. I will soon release a new version of SPMF with episode mining algorithms (in perhaps 1 week) that can deal with timestamps. Maybe it could be used. Otherwise, in SPMF, there are

Hi, You have understand the main idea about forward/backward checking. For closure jumping, the idea is not complicated. It is as follows. Let say that you have this database: A B C D F A C D F A C D E F A E You can count the support of the items: A = 4 B = 1 C = 3 D = 3 E = 2 F = 3 Since C, D and F have the same support, it means that they always appears together, and th

Hi, Yes sure. Assume that we have a total order on items such as A,B,C,D,E ... which is the alphabetical order. To be able to apply transaction merging efficiently, we need to sort the transactions. For some detailed example, consider the database on page 13 of this powerpoint presentation about EFIM: http://www.philippe-fournier-viger.com/EFIM_and_EFIM-Closed_high_utility_mining.pdf

Hi, You can use SPMF to apply FPGrowth and Eclat to a text file... but still the text file need to follow the required input format. Since there are so many possible format, the software cannot accept all the possible format. Thus, the solution would be to transform your file to the required format. The format used by SPMF is explained in the documentation section of the SPMF website. If

Hi again, That is a good observation. There would be very few algorithms of this type. The reason is that pattern-growth scan the database to see which items can extend a pattern. By doing this, pattern-growth algorithms avoid generating patterns that do not exist in the database. On the other hand, vertical algorithm are designed to avoid scanning the database. They combine two patterns

Hi, Thanks for your interest in the software! TKG currently only handles undirected graph. But I know that it could be modified for handling directed graphs. It is just that we did not do it. To modify it for directed graphs, since TKG is based on gSpan, one could just follow the instructions about how to modify gSpan for directed graphs, which have been described in p.9 of this paper: h

Good morning, An algorithm like PrefixSpan uses an horizontal database and do database projections. PrefixSpan is said to use a "pattern growth" approach. For me, I categorize the algorithms as follows: PrefixSpan: Horizontal database, pattern-growth, database projection, do a depth-first search CM-SPADE and SPAM: Vertical database encoded as bitvectors, generate candidates,

That announcement about Neon is a bit mysterious. But I personally don't expect much from this. I think it will be perhaps another chatbot but with speech generation ability and perhaps integrated into a robot. But we will see!

Dear Charles, Happy new year! Very interesting topic and problem. And I also see that you have put a lot of efforts and thoughts about this. Since this data is a very long sequence of itemsets, you could definitely apply an episode mining algorithm to that data. You could apply a frequent episode mining algorithm to find episodes that appear multiple times in your sequence. In episode

Hi, Thanks for your interest. We will release the code of that episode mining algorithm in the SPMF library very soon, in the next version. It should be in about 1 or 2 weeks. If you want more details about HUE-SPAN, the PPT and PDF of HUE-SPAN can be found here: - HUE-SPAN: Fast High Utility Episode Mining (article) - HUE-SPAN: Fast High Utility Episode Mining (ppt) Best regards,

Hi, Thanks for your message. super() is a special command in Java, which calls the constructor of a super-class. For example, calling super() in the ClusterWithMeans class has for effect of calling the constructor of the Cluster class (because Cluster is a super-class of ClusterWithMeans. Having said that, there is no particular reasons for calling super() in Cluster because it does no

I dont really agree. A machine can be "intelligent" without having to imitate human behavior. Even, a machine might be more intelligent if it does not behave like a human. Besides, there are other types of intelligence like animals, etc.

Hi, Thanks for using SPMF. Yes, indeed, increasing the window size constraint should increase the number of patterns. Maybe there is some problem with the input file? If you want you can send me to philfv8 AT yahoo DOT com with the parameter values that you used and I can test it. Best regards, Philippe

Hi, It would be great to receive your chapter submission! For the indexing, typically only journals can be indexed in SCI and SCIE. Since this is a book, it cannot be indexed in SCI/SCIE. But, Springer is a top publisher for books. It should give some good visibility to your paper, and it looks good to have a chapter in a Springer book!
