[SOLVED] Temporal Association Rules

Q-Dog

Hi,

is it possible to mine temporal association rules with RapidMiner (or temporal datamining in general)?

For Example:
"90% of the men who bought beer on friday, will buy headache tablets on saturday"

Cheers Q-Dog

Hi,

You could try the Generalised Sequential Patterns operator ?

Q-Dog

Thanks for your answer haddock, I just did.

But it seems there is an error with this operator. When I try to view the results of the GSPset, I get:

Error executing background job 'Creating Display'
java.lang.IndexOutOfBoundsException: Index 0, Size: 0

Exception: java.lang.IndexOutOfBoundsException

Can anyone reproduce this error?

Here is an example process with data from samples (only to demonstrate the error):

Sadly seems to work here!

Actually I've just posted elsewhere about association rules and referred here

http://rapid-i.com/rapidforum/index.php/topic,3619.msg13530.html#msg13530

So perhaps this operator suffers from the same problems as the association rules operator, and you could stave off disaster ( the Java choke messages ) by setting the frequency bar a bit higher.

As it happens I do a lot of exactly this," if A & B & C at T1 then is D true at T2 with sufficient frequency etc.". If you are looking for rules with only one item in the head then you can copy the attribute you want to represent D, move all the values up on example, do your itemset mining only and then look in the frequent itemsets for that new attribute. Simples!

Because I do this on ~1,000,000 timeslots I ended up writing an operator to outsource the actual itemset generation via a separate service, which is very fast at this, because it is CUDA based; also I needed to write an operator to do the next period peeking. It has revealed interesting stuff in my domain - but it did take quite an effort.

Good luck with your project.

I just tried to run your example process and for me it works too. Do you always get the error when running the process?

Greetings,
Nils

Q-Dog

Hmm that's a pity :-\

I get the error when automatically switching to the results view. The process itself works fine, the problem ony occurs when showing the results.

@haddock:
I did try lagging the attributes, unfortunately the offset between my attributes isn't constant. Therefore I wanted to use a time intervall

// Edit
I just uninstalled the newest version and reinstalled an older one (5.0.010) and now it seems to works. I wonder what will happen, if I update to the newest version again...

Nils_Woehler

Okay, I ran the process with the 5.2 release and now I got the same error. But with the current SVN versionthe error is gone. Someone must already have fixed the problem ;D
I should be gone with the next bugfix release...

Nils
