Typical applications include robot navigation,speech recognition,image recognition,natural language processing,and intelligent recommendation, among others.Among these applications,large language models (Large Language Models,LLMs)led by ChatGPT have gained popularity worldwide and have been widely promoted and used.While we fully recognize the rich,intelligent,and convenient experiences that these models bring to people.It is also important to be aware of the many risks associated with tools such as Al text generation.First,these large language models are trained based on text.And different types of languages and cultural backgrounds of different domains can have a significant impact on the generated results.Second, Al-generated results based on data may have semantic biases,lack logical coherence,and lack creativity.Finally,issues such as privacy protection, copyright protection,and the definition of related academic misconduct resulting from students using Al to generate papers pose significant difficulties and challenges to the teaching and training process for undergraduate and graduate students.In order to prevent the misuse of Al-generated text,ensure the quality of generated content,and discuss how to address the problems caused by Al-generated papers,it is necessary to identify and detect the patterns of Al-generated text according to the topic requirements,including fields,models,images,and formulas.To determine whether the text is Al-generated,in addition to considering factors such as meeting the word count requirement,the number of times generated,and whether it is Chinese-English translation. It is also important to note that Al currently lacks human emotion and judgment.This can lead to phenomena or styles in text generation such as “more phrases lack of examples,lack of emotion,structure,such as a single”Please use mathematical modeling to solve the following four problems:Problem one:Please use Al to rewrite some parts of the articlesaccording to the links of twenty blogs on the Web of Science provided in Appendix I.And look for the basic rules of AI text generation,which can be inferred statistically inferred from the requirements of the number of words to be generated by AI (e.g.200 words,500 words,etc.),the number of times to be generated (the first time to be generated and then click on the button of “Regenerate”),whether it is a translation of the Chinese and English.and the style of the generated text.Problem two:Please carefully consider whether each paragraph in the articles is generated by Al based on factors.This includes different generated languages,whether it is a translation,number of times generated,and whether there are restrictions on the number of output words,etc.for the theory and method of Al generation.Then mark the results of whether each paragraph in the ten articles provided in Appendix III is generated by Al.Problem three:For the theory and method of Al generation,please carefully consider whether each paragraph in the articles is generated by Al based on factors.It includes different generated languages,whether it is a translation,number of times generated,and whether there are constraints on the output word count,etc.for the theory and method of AI generation.Then,mark the results of whether each paragraph in the ten articles provided in Appendix IlI is generated by Al.Problem four:Please establish relevant theories and methods for further determining whether mathematical models,images,and formulas in the articles are plagiarized content.And use the examples in Appendix IV to demonstrate this and evaluate the established model.Title Statement:The questions are only used by the contestants of the 9th “ShuWei Cup” International Competition in 2023,and any form of tampering,editing and other purposes is strictly prohibited without the authorization of the Organizing Committee of the”ShuWei Cup”.Once found,it shall bear the relevant responsibility.
