Missing Value Filling Research Based on Ensemble Learning

This paper studies missing value filling and compares the filling effects of five methods: Mean, KNN, Random Forest, GBDT, and Stacking under different missing proportions, proving the superiority of ensemble learning algorithms in filling performance when multiple feature values are missing. Then the missing value filling method of KNN+integrated learning is proposed to further improve the filling performance.

Research on the Path of Cultivating Self-education Ability of College Students in the Perspective of Internet

At present, the cultivation of college students’ self-education ability is faced with the problems of inappropriate education methods in colleges and universities, the gap between students’ ideals and realities is too big, and the conflict between the internal and external drives of self-education. To achieve the development of college students’ self-education ability, colleges and universities have to innovate the cultivation methods, gather the three-dimensional synergies in and out of the classroom, and reasonably make use of the powerful role of rules and regulations, so that the cultivation of college students’ self-education ability will be effectively assisted.

Research on Strategies for Developing Language Sensibility in Upper Elementary Chinese Education

With the implementation of the 2022 version of the New Curriculum Standards for Compulsory Education Chinese (referred to as the Curriculum Standards hereafter), the focus on core literacy has become a central concern and inevitable trend in Chinese language teach_x005fing research. This paper, starting from the practical aspects of Chinese language learning in the fifth and sixth grades of primary school, investigates the language sensibility of upper-level students. Based on the findings regarding the sensibility status, it identifies a series of issues such as inappropriate methods and insufficient attention in the cultivation process and proposes specific strategies to address the current state of students’ language sensibility.

Research Status and Application of AirSource Heat Pump Technology

With the improvement of people's living standards, water heaters almost into the various households. In the energy-saving emission reduction has become the trend of the times today, saving energy and reducing carbon emissions is the most fashionable way of life. Air source heat pump water heaters are increasingly being used in people's lives. It is well known that it has many advantages, safety, energy saving, comfort, environmental protection, but there are some factors that affect its development and promotion. This paper mainly discusses the development history of air source heat pump technology at home and abroad, working principle, working flow, turbo technology at present stage, efficient heat exchange, and the research status of air source heat pump technology, such as new type refrigerant and dual frequency compression frequency conversion, then it discusses the application of air source heat pump technology, has the advantage, and finally discusses its application and the existence of two major problems and suggestions for improvement.

IoT in manufacturing: A bibliometric analysis of global research trends in computer science from 2013 to 2023

One of the main concerns in computer science today is integrating the Internet of Things (IoT) into manufacturing processes. This trend could influence a country’s strategy and policy development regarding technological infrastructure. However, despite extensive research on the implementation of IoT in manufacturing, no study has yet focused on the growing research interest in this topic. Based on 2487 papers indexed in the Scopus database between 2013 and 2023, this bibliometric review examines current trends and patterns in IoT research in manufacturing. The literature was selected and screened using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Data visualization was created using VOSviewer. The results show a notable increase in research papers centered around IoT in manufacturing. The findings reveal patterns and trends in IoT research publications in the manufacturing sector, author collaboration networks, country collaboration networks, and both established and newly trending topics surrounding IoT in the manufacturing industry.
