The use of machine learning can study the objective laws of the data to find out the relationship between the data, but also can achieve data classification and prediction. This article is based on national food safety sampling platform for dairy products testing data for the study to predict the risk safety of dairy products. Firstly, the sampling data of dairy products was selected from the database and the data was preprocessed. Then, the characteristic data were selected and classified into these data. Finally, the key food safety risk early-warning model was constructed by using Extreme learning machine (ELM) and the kernel-based extreme learning machine (K-ELM) respectively. Commonly used BP neural network and Support Vector Machines(SVM) network contrast. After ELM and K-ELM again to compare the experimental results. From the experimental results, it can be seen that the neural network algorithm based on kernel extreme learning machine has a high accuracy in food safety prediction and the training time is short. Through the extreme learning machine effective prediction of food safety, to regulate the quality and safety of food, so as to protect the quality of food safety in China.

Wheat is a vital staple food crop, and its post-harvest storage is paramount to maintaining its quality. However, conventional grain storage methods frequently impede the ability to promptly and accurately predict and assess quality changes. Moreover, most storage systems are ineffective in dealing with the impact of temperature and humidity fluctuations on wheat quality, which can potentially lead to quality degradation during storage. To address these challenges, this paper proposes a dual model system of “prediction-evaluation”, which integrates a dynamic quality prediction model based on SGCNiFormer with an evaluation framework based on K-Smeans clustering to establish a closed-loop mechanism from quality prediction to storage effect evaluation. The system incorporates a graph convolutional network (GCN) and a dynamic gating module, enabling precise simulation of the multidimensional evolution of wheat quality under the interaction of moisture and temperature. The experimental results demonstrate the superiority of SGCNiFormer in time-series prediction tasks, while the K-Smeans method establishes a wheat quality grading standard with physical interpretability. This integrated method provides a systematic theoretical framework for optimizing storage parameters and offers substantial support for intelligent grain storage management.

Named Entity Recognition (NER) and Coreference Resolution (CR) are both of pivotal significance in the domain of natural language processing. The accurate detection of pronouns and noun phrases has been shown to have a direct impact on cross-sentence and even cross-modal semantic understanding. However, existing methods often suffer from inadequate semantic fusion in multimodal scenarios, leading to issues such as text-image mismatches and incorrect referential resolution. The present paper proposes a multimodal generation framework that integrates object detection with prompt-based strategies. First, a prompt mechanism is employed to embed entity types into the visual channel using object detection results and hierarchical features extracted by a visual Transformer. This design enhances multimodal NER. Then, the PGMCR model is constructed, which aligns the pronouns and noun phrases identified by NER with the image regions based on prompt information to achieve generative multimodal co-reference resolution. The experimental findings on the public CIN dataset demonstrate that PGMNER attains an F1 score of 96.55% in the NER task, which is notably higher than that of representative multimodal models. PGMCR attains a CoNLL F1 score of 62.53% on the CR task, thereby surpassing existing state-of-the-art methods. These results provide validation of the effectiveness of the proposed framework in cross-modal named entity recognition and co-reference resolution, thus providing new insights for multimodal semantic understanding in complex scenarios.

Taking the technical requirements for the dynamicity and flexibility of software system in open network environment as cut-in points, this paper put forward a novel dynamic component model named SoftMan component (SMC) which was well-formed and evolvable. And then a distributed multi-task collaboration mechanism based on game theory in SoftMan component dynamic evolution system is put forward in order to maximize the utilization of computing resources and resolve multi-tasks collaboration problem. Three kinds of experiments are designed to test the feasibility, robustness and performance of distributed multi-tasks collaboration mechanism. Results show that distributed multi-tasks collaboration mechanism based on game theory has a higher success rate and accuracy with good algorithm stability and reliability.
