In this paper,a variety of classical convolutional neural networks are trained on two different datasets using transfer learning method.We demonstrated that the training dataset has a significant impact on the training results,in addition to the optimization achieved through the model structure.However,the lack of open-source agricultural data,combined with the absence of a comprehensive open-source data sharing platform,remains a substantial obstacle.This issue is closely related to the difficulty and high cost of obtaining high-quality agricultural data,the low level of education of most employees,underdeveloped distributed training systems and unsecured data security.To address these challenges,this paper proposes a novel idea of constructing an agricultural data sharing platform based on a federated learning(FL)framework,aiming to overcome the deficiency of high-quality data in agricultural field training. 展开更多

In this paper,a support method for business planning and management using software is proposed in order to increase productivity in small and medium-sized industries.Our targets are job shop type production factories,which manufacture products that meet specific demands from numerous customers.For these factories to be successful,speedy operational planning and effective management of operations progress for different models in variable quantities are essential.Moreover,effective production and operations management needs to be promoted.Thus,it is necessary to obtain a tool that enables the maximization of throughput using a bird’s-eye view of the entire shop floor and understanding it from the viewpoint of optimization.In our study,planning production and expediting follow-up are conducted using Gantt charts.The system is a simple analog tool that heuristically supports production management through worksite knowledge and experiences without conventional approaches.Furthermore,robotic process automation(RPA)was introduced to reduce the workload of workers.The effectiveness of this prototype system was confirmed by a review of different people in charge. 展开更多

Ensuring the general efficacy and benefit for human beings from medical Large Language Models(LLM)before real-world deployment is crucial.However,a widely accepted and accessible evaluation process for medical LLM,especially in the Chinese context,remains to be established.In this work,we introduce“MedBench”,a comprehensive,standardized,and reliable benchmarking system for Chinese medical LLM.First,MedBench assembles the currently largest evaluation dataset(300901 questions)to cover 43 clinical specialties,and performs multi-faceted evaluation on medical LLM.Second,MedBench provides a standardized and fully automatic cloud-based evaluation infrastructure,with physical separations between question and ground truth.Third,MedBench implements dynamic evaluation mechanisms to prevent shortcut learning and answer memorization.Applying MedBench to popular general and medical LLMs,we observe unbiased,reproducible evaluation results largely aligning with medical professionals’perspectives.This study establishes a significant foundation for preparing the practical applications of Chinese medical LLMs. 展开更多
