Fig. 6: Test results of estimated capacity versus real capacity by transfer learning.
From: Data-driven capacity estimation of commercial lithium-ion batteries from voltage relaxation

The capacity results are uniformized by the nominal capacity for comparison. Results of TL2 embedding XGBoost method (a) and embedding SVR (b) on dataset 2. Results of TL2 embedding XGBoost method (c) and embedding SVR (d) on dataset 3. Additional results are disclosed in Supplementary Figs. 10–12.
