decoder weights of M (P ) using the data of 17 coin cells from D LN O , resulting in an updated model, M (P ) f . This fine-tuning process is detailed in Supp. 14, and led to a substantial improvement in predicting Q dis , dropping the RMSE to 0.0002, indicating a significantly enhanced precision. M (P ) f 's performance will be compared with M (B), trained with the BASF dataset B, in the following section.
