Abstract Existing Transformer-based models for fine-grained image classification often struggle to explicitly model the granular hierarchical relationships among multi-scale features and perform adaptive fusion. This limitation leads to the insufficient utilization of discriminative features. Inspired by granular computing theory, this paper proposes a Multi-Granularity Collaborative Network (MGCN-FGIC) that integrates core operations—including granulation, enhancement, alignment, and fusion—into a deep learning framework. Specifically, the network reorganizes and enhances backbone features via a Granule-aware Enhancer and achieves adaptive collaborative fusion of cross-granularity information using a Granule Fusion Neck. Furthermore, a Dynamic Hard Example Mining mechanism is designed to trigger multi-granularity supervision based on sample difficulty, thereby improving discriminative ability for challenging examples. The proposed method achieves classification accuracies of 92.95

Credit risk assessment is an important process in bank financial risk management. Traditional machine-learning methods cannot solve the problem of data islands and the high error rate of two-way decisions, which is not conducive to banks’ accurate credit risk assessment of users. To this end, this paper establishes a federated three-way decision incremental naive Bayes bank user credit risk assessment model (FTwNB) that supports asymmetric encryption, uses federated learning to break down data barriers between banks, and uses asymmetric encryption to protect data security for federated processes. At the same time, the model combines the three-way decision methods to realize the three-way classification of user credit (good, bad and delayed judgment), so as to avoid the loss of bank interests caused by the forced division of uncertain users. In addition, the model also incorporates incremental learning steps to eliminate training samples with poor data quality to further improve the model performance. This paper takes German Credit data and Default of Credit Card Clients data as examples to conduct simulation experiments. The result shows that the performance of the FTwNB model has been greatly improved, which verifies that it has good credit risk assessment capabilities.

By studying the simulated process of teacher-to-teacher assessment, the article elaborates on the scientificity and objectiveness of the application of AHP in assessing teachers' comprehensive working performance. Through computer programming, AHP is put into practice in the field of scientifically assessing teachers' working performance. Furthermore, it argues for the application of database in managing and assessing data as well as computer software in evaluating and calculating. This software also is applicable to other kinds of multiple-objective decision-making and assessing.

A Weighted Relational Classification Algorithm Based on Rough Set is proposed in this paper. The relations of tables are classified in database, relational graph is converted into 0 - 1 matrix, the weight is calculated using UCINET, at the same time, different condition attributes are weighted differently by using attribute frequency of Rough Set. It is improved effectively. Experiments have proved that new classifier has good classification performance.

Content management technology is an integrated application of many advanced technologies, focused on solving a variety of unstructured or semi-structured digital resources collection, management, use, transmission and value-added, and can be integrated into the structure of organic-based data, business intelligence environment. this paper puts forward a method to construction Course-Education website with the content management technology, this method can separate webpage manufacture, layout technology and the course content, fundamentally solves the bottleneck of technology and the content, role division of the maker and the teacher. Take computer network as an example, this paper introduces the Course-Education Website Construction applying content management system.

Computer Application Fundamental Course is a basic course for students in universities, and is a leading course of learning computer programming language. So teaching effectiveness is very important for students. Considering a number of issues, such as a computer uneven level of college freshmen, teaching the content of complex, high precision operation, and so on, this paper propose the teaching methods which combined with a variety of factors(Level-Differentiated Teaching Methods, interactive effects, etc). Through building the site, to broaden students' learning space and to expand teaching content; Through examination reforms, to stimulate students' hands-on initiative. We made well teaching results in teaching practice, which greatly improve students' pass rate of grades exam. © 2010 IEEE.

By comparing several different Tree Graph Algorithm,this paper gets their superiority-inferiority.So that we can choose a method or a combination of several algorithms to meet the needs of users.

Clinker strength prediction in cement factory is a subjective process.The Skowron matrix-which belongs to Rough Set is applied to calculate influence factors to clinker strength.By this method,the main factors influncing clinker strength can be chosen.In further re- search,clinker strength is predicted scientifically so that the quality of the cement on sell can be guaranteed.Reliable theoretical basis is pro- vided for clinker strength prediction.

The implications of stable epistemologies have been far-reaching and pervasive. The synthesis of red-black trees has been validated in the paper. An atomic tool for investigating Smalltalk (Titi) was described, disconfirming that sensor networks can be made peer-to-peer, stable, and adaptive. Firstly, motivated the need for neural networks, validated the emulation of symmetric encryption. Furthermore, we prove that the well-known adaptive algorithm for the exploration of IPv4 by Sasaki et al. runs in O(n!) time.
