This invention relates to a method for predicting the thermal storage performance of materials based on multi-source domain knowledge distillation.

Second, the crystal structure and various readily available physicochemical properties of a second sample are searched, and multiple source domain pre-training datasets are constructed by grouping according to different parameters. Next, isomorphic second models are trained using each source domain dataset, with each model predicting one physicochemical property parameter, and its second intermediate layer feature representation is extracted. Then, a first model with the same structure as the first sample is trained to predict the thermal storage performance parameters, and knowledge distillation is introduced during training: the intermediate layer features of each second model are fused using learnable weighted methods to generate reference features. The difference between these reference features and the first intermediate layer features of the first model is calculated, and the model is optimized by combining the error of the predicted values. Finally, the crystal structure of the sample to be predicted is input into the trained first model to obtain the predicted thermal storage performance parameters. This method is suitable for small-sample scenarios with limited thermal storage performance label data and can provide rational guidance for the design of thermal storage materials.
