AI Technical Summary
Traditional physical information neural networks are inefficient and inaccurate when tracing the source of heat and mass transfer over long periods, making it difficult to simulate reverse heat and mass transfer problems.
A physical information kernel function is introduced as the activation function of a neural network. A physical information kernel function neural network is constructed. By combining the boundary and final conditions of the diffusion equation, a loss function is constructed by modifying the source term. The neural network is then trained to trace the heat and mass transfer dynamic data at any historical moment.
It enables rapid and accurate tracing of heat and mass transfer dynamic data at any historical moment, overcoming the computational bottleneck of traditional methods, improving accuracy and efficiency, and is suitable for fire origin analysis, pollutant tracing, and drug molecule delivery path inversion.
