Researchers have developed MetaARIMA, a novel approach that applies transfer learning to classical ARIMA time series forecasting models. Unlike previous methods that configure models independently for each series, MetaARIMA uses meta-learning to learn from historical experiments which ARIMA configurations yield the best results. This policy then recommends promising candidates for new time series, maintaining interpretability and local estimation. Experiments show MetaARIMA outperforms AutoARIMA and is competitive with recent foundation models like Chronos2 and TimesFM, particularly in data-efficient scenarios. AI
