Characteristics of different models.

Decomposition techniqueTwo-layer decomposition technique

VAR (model 1)
BPNN (model 2)
RF (model 3)
ARIMA (model 4)
ELM (model 5)
XGBoost (model 6)
SVR (model 7)
SOA-SVR (model 8)
VMD-SOA-SVR (model 9)
VMD-CEEMDAN-SOA-SVR (model 10)
CEEMDAN-SOA-SVR (model 11)
CEEMDAN- RES.-SOA-SVR (model 12)
CEEMDAN -RES.- VMD -SOA-SVR (model 13)

Ps: model 12 and model 13 are decompositions that include the residual term after the first decomposition.
