Dimensionality Expansion of Load Monitoring Time Series and Transfer Learning for EMS

no code implementations6 Apr 2022 Blaž Bertalanič, Jakob Jenko, Carolina Fortuna

Investigating the proposed method for cross-dataset intra-domain transfer learning, we find that 1) our method performs with an average weighted F1 score of 0. 80 while requiring 3-times fewer epochs for model training compared to the non-transfer approach, 2) can achieve an F1 score of 0. 75 with only 230 data samples, and 3) our transfer approach outperforms the state-of-the-art in precision drop by up to 12 percentage points for unseen appliances.
