Meta-learning approaches to selecting time series models

Ricardo B.C. Prudêncio, Teresa B. Ludermir
2004 Neurocomputing  
We present here an original work that applies meta-learning approaches to select models for time-series forecasting.  ...  Following, we used the NOEMON approach, a more recent work in the meta-learning area, to rank three models used to forecast time series of the M3-Competition (case study II).  ...  Hence, landmarking would be an economic approach to the data characterization step and could provide useful information for the meta-learning process.  ...
