HANA PAL Random Forest Regression - Confusion Matrix?

291 Views

Hi,

I would like to use Random Forest from PAL for a Regression Task. I used the example as shown at Random Forest - SAP HANA Predictive Analysis Library (PAL) - SAP Library and it works perfect for classification.

Unfortunatly there is no example for regression so I'm not sure what to with the Confusion Matrix. The Confusion Matrix Table is a parameter expected by the RANDOMFORESTTRAIN function but can not be used with regression. If I try to use RANDOMFORESTTRAIN for an regression task anyway I get an error: [2620] executor: plan operation failed;Can not insert data from temp table "SCHEMA:P6_578EC76B35627559E10000000A443055 (t -1)" into table ""SCHEMA"."PAL_RF_CONFUSION_TBL"".


I already tried to use RANDOMFORESTTRAIN without the Confusion Matrix as a parameter, but then also get an error.


Has someone successfully implemented PAL Random Forest for regression? An example would be great.

Thanks a lot in adavance 😊
