Abstract: Foetal weight prediction is important for foetal development and safety of pregnant women. However, foetal weight can only be roughly predicted using the ultrasound data set of pregnant women, and the prediction accuracy is still low. In this paper, we propose a prediction model, termed PSO-GRNN, which is based on Particle Swarm Optimisation algorithm and Generalised Regression Neural Network, in order to obtain the foetal weight using the physical examination data and ultrasonic data of pregnant women. The historical data of pregnant women's examination are pre-processed firstly, and a prediction model is established by GRNN and then the parameters of the prediction model are optimised to reduce human interference by using improved particle swarm optimisation algorithm. The experimental results show that on average compared with some state-of-the-art algorithms, the Mean Relative Error of the proposed method is 1.33% lower and the accuracy of foetal weight prediction is 4.15% higher respectively.
