Time Series Prediction Model by Kotu And Deshpande 2015

Time Series Prediction Model by Kotu And Deshpande 2015

I am trying to set up the Time Series Prediction model example that is found in Kotu/Deshpande - Predictive Analytics using Rapidminer - 2015

I got most of the model connected but I cannot find a few of the operators used in the article...

One operator it calls for is...Extract Example...that connects from the 2nd Window box and then output to the Filter Example box...

"Extract Example" operator is not in RMS v6.5...

Same with "Increase Date" operator...used for the Loop...not found.

Are there a suitable replacements for these operators for this particular Time Series example...?

BTW...thanks to the authors... One of the best descriptions on Time Series windowing I have read.

Now it would be really great if I can find the right operators to get this neat Time Series example working in Rapidminer...!

Thanks,
Robert

I don't know those operators as well. But as you might know, operators can be renamed. Maybe this is a standard operator renamed to this.

Hi there,

I checked on the authors on Amazon and found

Predictive Analytics and Data Mining: Concepts and Practice with RapidMiner Paperback – 3 Dec 2014

So the example may be for an earlier version. The labels like "Extract Example" are unfamiliar to me also, so they probably have been renamed by the authors, whom you'll need to contact.

Hi Martin and Haddock...

Thanks to you both for your suggestions...

Martin...any idea which "standard operators" would do the same thing as those specific two operators in the article...?

I'm still a novice and am still learning what they all do and don't know which ones might work here.

Haddock...the article I have is a PDF published by Elsevier - Copyright © 2015 Elsevier Inc. That may be the same 2014 article as you listed or revised...and I would hope that the more recent one uses the latest RMStudio version...

But the difference in operator names suggest it is using an older version of RMStudio. Also...contacting the authors is a good suggestion as they seem to be still around...so I may try that later.

In the meantime...to all... Has anyone else tried this Time Series model example by Kotu/Deshpande and got it to work...?

Or does anyone have other Time Series examples that I can try for RMStudio v6.5...?

I was going to upload the two screens with the two specific operators that I need to find or replace for this Time Series example...

But I see the "image" icon... with no way to upload any images...? Am I missing something here or are uploads not allowed?

I also wanted to upload the Kotu/Deshpande article so others could try the example..but again could not find any file upload process?

Thanks in advance for any help with this.

Perhaps, and perhaps not.

I downloaded the code. The "unusual" operator are renamed operators.

1) Extract Example .. is an Extract Macro that extracts the number of examples.

2) Increase Data is a "Generate Attributes" operator that defines the variable "Date" as date_add(Date, 1, DATE_UNIT_MONTH)

Here's the code he uses:

Hi Earmijo,

Thanks for your good suggestions.

The coding part is a few steps beyond where I am as a novice coder...and I'm not sure how or where to add that to my process.

However your explanation really helps me understand what the operators are trying to do...and you gave me some more things to learn about and try for this example...

I'll work on it more during the weekend...

Take care and thanks,
Robert
