Beam Detection Based on Machine Learning Algorithms

1 Aug 2023  ·  Haoyuan Li, Qing Yin ·

The positions of free electron laser beams on screens are precisely determined by a sequence of machine learning models. Transfer training is conducted in a self-constructed convolutional neural network based on VGG16 model. Output of intermediate layers are passed as features to a support vector regression model. With this sequence, 85.8% correct prediction is achieved on test data.
