Abstract In the establishment of differential equations, the determination of time-varying parameters is a difficult problem,
especially for equations related to life activities. Thus, we propose a new framework named BioE-PINN based on a
physical information neural network that successfully obtains the time-varying parameters of differential equations.
In the proposed framework, the learnable factors and scale parameters are used to implement adaptive activation
functions, and hard constraints and loss function weights are skillfully added to the neural network output to speed
up the training convergence and improve the accuracy of physical information neural networks. In this… More >
