多目标的回归问题用一个模型训练好还是用多个模型训练好?

多目标的回归问题(MTR, Multiple Target Regression)

Why use multi-output models instead of a combination of single-output models like regression?

  • Models using single outputs take longer to train and are computationally expensive
  • They optimize for the single target rather than all the targets together
  • They do not use relationships between the target variables (Y)
  • MTR regression models are simpler than a stack of Single Target models
  • MTR trees provide human-readable predictive models and the models are easily interpreted.
