calling gbm function

I am trying to run PMML model from C#. I am trying to simulate below R code from C#.

Validation <- predict.gbm(UPC80.tc2.lr01.simplify.10  , Validatedata , n.trees=UPC80.tc2.lr01.simplify.10$gbm.call$best.trees                  , type = "response")

Here is the package info  http://cran.r-project.org/web/packages/gbm/gbm.pdf

How do we call predict.gbm function using syncfusion framework?

Hi Vijaya,

Thank you for your interest in Syncfusion products.

At present we don’t have support for GBM model in our PMML Execution Engine. We are providing support for the following models from Data mining Groups:

1.     Clustering Model

2.     Cox Regression

3.     General Regression Model

4.     Multinomial Regression

5.     Naïve Bayes

6.     Neural Network

7.     Random Forest (Mining Model)

8.     Regression

9.     Support Vector Machines

10.   Tree Model


PMML Execution Engine is a PMML consumer which consumes the input PMML and creates an evaluator instance for the appropriate model which in turn invokes the respective scoring procedure for prediction when GetResult method is called. For more information about PMML execution engine, please refer the following documentation link:



Moreover we use R Script to generate the PMML file and carry only the generated PMML file to our PMML Execution Engine for prediction, not the R codes to C# environment. 

Kindly let us know if you have any further assistance on this.

Hi Vijaya,

Please ignore our previous update.

We are investigating the execution procedure for GBM model and we will update you with the details within two business days 03/03/2015.

Hi Vijay,

Still we are investigating the gbm model and we will update you the details in two business days (3/5/2015).
