This study examines ways to create personalized learning pathways that are influenced by large collab.rative models and multi-modal knowledge graphs. By integrating multi-modal data to construct a comprehensive knowledge network, this study utilizes the generative and comprehension capabilities of large models to achieve personalized customization of learning resources. The focus of the research is on accurately depicting learner characteristics through multi-modal profiling techniques, ensuring the transparency and credibility of the content generated by large models. The personalized learning route suggestion model proposed in this paper includes two parts: recommendations for learning paths within courses and recommendations for learning paths within learning tasks, aiming to enhance learning efficiency and outcomes through the collab.rative effects of multi-modal knowledge graphs and large models. Experimental results indicate that the learning path recommendation model driven by multi-modal knowledge graphs and large collab.rative models performs excellently in improving learning outcomes and recommendation performance. © 2024 IEEE.

Piston compressors are widely used in chemical industry and other fields. At present, the market puts forward a working condition requirement for piston compressor to adapt to the change of intake air volume. However, the classical PID control has shortcomings in stability time, anti-interference and PID parameter online tuning, which does not meet the requirements of working conditions. Therefore, this paper designs the adaptive control system of the intake air volume of the piston compressor according to the variable speed air volume regulation strategy and establishes a mathematical model. Using BP neural network and fuzzy control theory, a fuzzy neural network PID controller is built. Using Matlab.Simulink, a step response simulation experiment is carried out. Using C# language, the upper computer of the system is programmed. The simulation results show that the stability time of the intake air volume adaptive control system based on the fuzzy neural network PID controller is 1.63 seconds, which is 0.55 seconds and 1.6 seconds faster than that of the intake air volume adaptive control system based on the adaptive fuzzy PID controller and the classical PID controller respectively, and its anti-interference ability is stronger, which is more suitable for the realization of the intake air volume adaptive control system controller under this working condition. © 2023 IEEE.

An adaptive kernel learning (AKL) networks is proposed to model the industrial analyzer and meanwhile monitor its potential faults, which utilizes kernel function and geometric angle to build an adaptive network topology. Two forms of learning strategies for AKL networks are obtained and their corresponding recursive algorithms are developed, respectively. The proposed AKL algorithm applies to nonlinear MIMO modeling issues with controlled generalization ability. Numerical simulations on Tennessee Eastman (TE) proc.ss show that the proposed AKL networks can learn and monitor online the dynamics of the composition analyzer using relatively small samples, under stochastic and fault-existing environment.

Document images belong to a unique class of images where the information is embedded in the language represented by a series of symbols on the page rather than in the visual objects themselves. Since these symbols tend to appear repeatedly, a domain-specific image coding strategy can be designed to facilitate enhanced compression and retrieval. In this paper we describe a coding methodology that not only exploits component-level redundancy to reduce code length but also supports efficient data access. The approach identifies and organizes symbol patterns which appear repeatedly. Similar components are represented by a single prototype stored in a library and the location of each component instance is coded along with the residual between it and its prototype. A representation is built which provides a natural information index allowing access to individual components. Compression results are competitive and compressed-domain access is superior to competing methods. Applications to network-related problems have been considered, and show promising results.

Kawasaki Steel has been making efforts to develop new hot-rolled steel products by using fully continuous rolling technology, so-called `endless rolling', at No. 3 hot strip mill of Chiba Works. Stable rolling technology of ultra-thin hot rolled strips such as 1.0 mm, 0.9 mm, and 0.8 mm in thickness has been established, and the conventional minimum gauge of hot rolled strips (1.2 mm) has been lowered. The ultra-thin hot rolled strips have been provided to the market with a brand name `RTHC' (River thin hot coil commercial grade) since 1977. The ultra-thin hot rolled strips have excellent quality in dimensional accuracy and mechanical properties. In addition, the ultra-thin hot rolled strips meet current needs of energy saving and reducing CO2 emission. New market and more demands for the newly developed product strips are expected.
