We published a paper on AI-driven cross section prediction. In this paper, we propose Deep Cross Section Network (DeepCSNet), a deep learning approach designed to predict electron-impact ionization cross sections using limited training data. DeepCSNet has two configurations: one tailored for specific molecules and another for various molecules. Both configurations can typically achieve a relative L2 error less than 5%. Additionally, DeepCSNet shows promising results in predicting cross sections for molecules not included in the training set, even large molecules with more than 10 constituent atoms, highlighting its potential for practical applications.

We published a review paper on AI-driven low-temperature plasma (LTP) simulation. In this review, we first introduce mainstream LTP simulation models, including kinetic models, fluid models, chemical dynamics models, and hybrid models. We analyze the problems faced by traditional LTP numerical simulation methods from four aspects: model complexity, numerical computation, parameter consistency, and result reliability. Then, we discussed the current research status of AI-driven LTP numerical simulation Finally, from the perspective of convergence and generalization, we summarize the challenges faced by relevant research and proposes further development directions.

We published a paper on visual classification and detection of power inspection images based on federated learning. In this work, a federated learning (FL) based method for processing power inspection images, which allows different data owners to cooperatively train visual classification and detection models without sharing their local images. To improve the training efficiency, we further propose a Federated Round-level Momentum (FedRM) method by adding a momentum term during the aggregation of model weights. We demonstrate the proposed method in three real-world power inspection image datasets for visual classification, object detection and defect detection tasks respectively
