Linear Discriminant Analysis with polynomial label

s96142

Does "Linear Discriminant Analysis" can process "polynomial" label?

The "F1" help information of the operator show "support polynomial label"

 

but with polynomial label dataset as input，run process will show error

 

I use the lasted V8.2 versionI, and I see some v6.xx version sample video can process 

 

this is the v8.2 probem?

Hi again @s96142,

 

You made a mistake in the parameters of the Filter Examples operator. Here the right filters :

After fixing it, the process can run without problem.

Thank you!

Hi @s96142,

 

I ran some of my processes with LDA and polynominal label using RapidMiner 8.2 and RapidMiner 9.0 : 

RapidMiner don't raise an error....

So are you sure to have effectively set your label as "polynominal" ? (maybe your label is initialy "numerical"....)

 

Can you share your process and your dataset(s) in order we can reproduce what you observe ?

 

Regards,

 

Lionel

I practice the sample in "Data Mining for The masses" which download from your website（page 124/264）.

Below is error message：

s96142

This is my process and dataset.
