RequestSampleSizeUpdate: Refits an existing model to a different fraction of the...

Description Usage Arguments Details Value

View source: R/RequestSampleSizeUpdate.R


This function requests a refit of the model defined by the model parameter to the same training dataset used in building it originally, but with a different fraction of the data, specified by the samplePct parameter. The function returns an integer value that may be used with the function GetModelFromJobId to retrieve the model after fitting is complete.


RequestSampleSizeUpdate(model, samplePct)



An S3 object of class dataRobotModel like that returned by the function GetModelObject, or each element of the list returned by the function GetAllModels.


Numeric, specifying the percentage of the training dataset to be used in building the new model.


Motivation for this function is the fact that some models - e.g., very complex machine learning models fit to large datasets - may take a long time to complete. Splitting the model creation request from model retrieval in these cases allows the user to perform other interactive R session tasks between the time the model creation/update request is made and the time the final model is available.


Integer, value to be used as the modelJobId parameter in calling the function GetModelFromJobId to retrieve the updated model.
