"PCA timeseries forecast plugin"

sandys13

For my experiments I have made the operator to forecast timeseries with PCA.

In attached file:
- picture describe used method,
- operator scource,
- plugin and examples.

Operator's main objectives:
- provide predictions as probability distribution,
- predict horizon>=1,
- multi-timeseries ability.

Operator is very poorly integrated into the RM, because I do not know all the possibilities RM.

I appreciate any criticism and suggestions.

Hello,

I had a look into your operator and it seems nice. Here is only a small comment: instead of using strings like "Step", "Halfwidth" etc. in the source I would like to recommend using constants like PARAMETER_STEP = "step" so that developers can easily access those constants from within their own programs.

If you would like to have this opetor integrated into the official RapidMiner release, please have a look on the page at

http://rapid-i.com/content/view/51/81/

Please note the part about the JCA since without that we cannot integrate contributions from others.

All the best,
Ingo

Hello,

I have tried to accommodate all the requirements described on the http://rapid-i.com/content/view/51/81/.

http://sourceforge.net/tracker/index.php?func=detail&;aid=2688292&group_id=114160&atid=667393

If this operator will be integrate into the official RapidMiner release, how will I be able to correct errors in it?

Hi,

thank you for contributing. We will have another look at your code as soon as we can. If all requirements are met (did you send us the signed Joint Copyright Agreement?), we will integrate your code in RM. Concerning the error correction there are at least two ways: (1) a post in the forum, (2) a bug report in the bug tracker at sourceforge. Probably the error correction is the fastest, if you submit a patch there.

Kind regards,
Tobias

This operator has not used, except me.
So I think before integrate in the release of better accumulate comments from users.
This period may take a long time, so I have not yet signed the Joint Copyright Agreement.
I look forward to comments from users, so I still left the operator code at the level of development.

I do not know how to proceed with the integration in to RM.
