Generalized Sequential Patterns (GSP) dataset format

Hello,

i have seen some posts about this subject but i didn't see any good answer.

Can anyone say the format of the input dataset for GSP???

The only format that i have some results (bad ones) is like this:

Client_id, time , feature 1, feature 2, ....
1,1,0,1,0,...
1,2,1,1,1,....
2,1,0,0,0

Hi,
this is already the correct format, you only need to turn the feature 1, feature 2, ... attributes into binominal ones. Use the Numerical To Binominal for this.

Greetings,
Sebastian

abdero,
Can you post the XML of how you got your data in the format:

Client_id, time , feature 1, feature 2, ....
1,1,0,1,0,...
1,2,1,1,1,....
2,1,0,0,0

Everytime I try to pivot my data from this format:
Customer, Time, Item
1,1,a
1,1,b
1,2,a
2,1,c
etc

I fail to get your format.
Thanks,
Will

Hi, unfortunately, the Pivot operator is currently only capable of grouping by one single attribute, so you have to combine client id and time before the Pivot operator and separate them afterwards. Please have a look at the attached process.

Best regards,
Marius

Marius,
Thanks for the timely response, I will examine the code you provided.

Marius,
I actually applied your logic to my SQL and concat'd before rapid miner which speeds up processing.

The trouble I have now is, when I pivot and attempt to replace missing values, that process doesn't work.

I result in a green lighted process but still have '?' values in my pivot table.

Example of my data:

Time_Customer Item Count
1_9 a 1
2_9 b 1
3_9 c 1
3_9 d 1
3_9 e 1
3_9 f 1
3_9 e 1
3_9 b 1
4_9 c 1
4_9 b 1
1_22 c 1
1_27 c 1
1_27 a 1
1_27 g 1
2_27 c 1
2_27 h 1
2_27 g 1
3_27 c 1

Hi,

please examine your Replace Missing Values operator. You are replacing the values of only one attribute, but in reality you probably want to replace missing values in *all* attributes, right?

Best regards,
Marius

willgouldin

Marius,
Thank you for your help, I got it to work. The code for reference is provided below. I do have one more snag, the output of the GSP Set works in a Mac OSX install but not in Windows 7.

In the Win7, I see summary data in the results overview tab, but when moving to the GSPSet(GSP) tab, all I see are the annotations options. In the Mac OSX instance, everything appears as one would expect.

Not sure if I should submit a bug report or what.

Thanks for your help!

Will

Hey Will,

are you using the RapidMiner 5.3.7 on both your machines?

Best regards,
Marius

willgouldin

Yes Sir. Updated this morning and it still produces the "error".

Will

MariusHelf

I could reproduce that behavior under windows, and it is obviously a bug. I created an internal bug report for that, so no need to submit a bug from your side.

Best regards,
Marius

willgouldin

Outstanding Marius,
Thank you for your assistance!

Will

willgouldin

Marius,
Another question concerning GSP. I receive the same result sets regardless of my Window, Min and Max Gap setting.
My raw data is using days between events as the time element.

Is this a function of the same bug we previously found?

Thanks,
Will

I can't imagine that the the two issues are related.
Did you inspect your data and make sure that the entered values actually would make a difference?

Best regards,
Marius

Marco_Boeck

Hi,

we've just fixed the "empty GSP results" bug. You can either checkout the latest SVN version (see here, updated around midnight) and build RapidMiner yourself, or wait for the next release.

Regards,
Marco

willgouldin

Marco,
Thanks for the response, I'll check my updates!

Hello dear Rapid I developers,

my GSP empty problem still exists till now, how can i update my Rapidminer? or do I need to wait until next official update? Could anyone tell me at what time?

Thank you!

willgouldin

I am curious as to when the next release will be that covers this as well.

Thanks,
Will

MariusHelf

Will, we don't have any release schedule targeted at the great public yet.

Not to dig up an old topic, but I am still having trouble with the data layout for the GSP operator.

I have combined the time (in day of year format) with my customer ID per your instructions. I have a column for item and a binomial value for the "qty".

When I import the excel sheet, pivot, replace the missing values with value "false" and then split, everything looks good.

When I attempt to convert the split columns for time and customer from nominal to numerical per the GSP operator requirements, my pivot is ruined.

I expect :

Customer, time, item a, item b, ......
1,1,TRUE, FALSE
1,3,TRUE, FALSE
2,4, FALSE, FALSE
etc

however it turns time into multiple columns within the pivot as well.

I can provide a larger example data if required for trouble shooting.
Any help that can be provided is appreciated.

Will

Hi
Do we have any operator to apply GSP rules

Thanks

MBM

this is a really good question
