  • Ticket #2882

    • Property Priority changed from medium to high
    • Property Component changed from Algorithms.DataAnalysis to Problems.DataAnalysis
    • Property Type changed from enhancement to defect
    • Property Summary changed from Create GBT-model lazily after deserialization to Deserialization of RegressionModels triggers a recalcuatlion of estimated values

  • Ticket #2882 – Description

    initial v1  
    1 On deserializing a gradient boosted tree solution, the GBTSurrogateModel recaltulates the actual GBTModel even if the model is not yet used - which can be quite runtime expensive.
     1On deserializing a gradient boosted tree solution, the GBTSurrogateModel recaltulates the actual GBTModel even if the model is not yet used - which can be quite runtime expensive. The same issue applies to all regression models.

    33Instead, the model should only be created when the model is actually needed to estimate values.
