In the realm of power Internet of Things (IoT) networks, secure inspection detection (SID) is paramount for maintaining system integrity and security. This paper presents a novel framework that leverages deep learning-based semi-autoencoders in conjunction with a hybrid recommendation algorithm to enhance SID tasks. Our proposed method utilizes the deep learning-based semi-autoencoder to effectively capture and learn complex patterns from high-dimensional power IoT data, facilitating the identification of anomalies indicative of potential security threats. The hybrid recommendation algorithm, which combines collaborative filtering and content-based filtering, further refines the detection process by cross-verifying the identified anomalies with historical data and contextual information, thereby improving the accuracy and reliability of the SID tasks. Through extensive simulations and practical data evaluations, our proposed framework demonstrates superior performance over conventional methods, achieving higher detection accuracy. In particular, the detection accuracy of the proposed scheme is more than 20% higher than that of the competing schemes.

Aiming at the problem that existing knowledge graph-based recommendation algorithms do not fully utilize the interaction information between users and items, this paper proposes a recommendation algorithm called Gated Adaptive and Knowledge-Enhanced recommendation (GAKR) that integrates an adaptive gating mechanism with knowledge graph enhancement. First, GAKR uses a Multilayer Perceptron (MLP) in the recommendation module to process the user's initial feature vector and extract potentially compressible features. Then, for the item feature vector, the model dynamically adjusts the weights of Collaborative Filtering (CF) and Knowledge Graph (KG) through the gating mechanism, generating a more expressive item representation. The gating mechanism calculates the gating value through the sigmoid function, allowing user's behavioral characteristics in different scenarios to more accurately impact item recommendation. Next, in the Knowledge Graph Embedding (KGE) module, an embedding interaction mechanism is designed, which updates the entity embeddings by using Mobius addition and mapping, capturing higher-order interaction information between entities and relations. To prevent overfitting, GAKR employs L2 regularization during the optimization process, which enhances the model's generalization ability when handling complex interactions. Finally, a normalized inner product operation is used as an evaluation function to predict the user's preferences for items. The experimental results on three public datasets from different domains-MovieLens-1M, Book-Crossing and Last. FM-show that the GAKR model outperforms other benchmark models in terms of the evaluation metrics such as AUC, F1-score and recall rate in the CTR (Click Through Rate) and Top-K recommendation scenarios.

Recommender system is widely used in e-commerce, news consulting, social networking, tourism, film, music and other fields because it can effectively deal with the problem of information overload. According to the practical problems in the recommendation system, various recommendation algorithms are produced. Traditional recommendation algorithms are divided into content-based recommendation, collaborative filtering based recommendation and hybrid recommendation. Collaborative filtering algorithms are favored because they can extract and process relevant information features to accurately predict user preferences. However, collaborative filtering algorithms generally have problems such as sparse data, cold start and data scalability. This paper presents the Associated Residual Matrix Factorization (ARMF) model, which can solve the common cold start problem and improve the recommended performance. The model uses associative residual neural networks (ARNs) to model higher-order interactions between the user and the underlying features of the item and to avoid network layer gradients exploding or disappearing and overfitting problems. In order to verify the validity and correctness of the model, this paper conducts tests on Movielens100k and Movielens10M datasets, and the experimental results show that the prediction results are 17%similar to 23% better than other comparison algorithms.

With the rapid development of network technology, recommendation systems attract increasing research because of its wide applications in e-commerce. Nevertheless, most existing recommendation models based on graph neural networks do not consider the transitivity of subgraph structures in interactive data. This makes the models unable to capture the complex dependencies and mutual influences between users and items, resulting in the inability to achieve high-quality personalized recommendations. To address the above challenge, we propose a novel recommendation algorithm based on knowledge graph with high-order graph convolutional network, named KG(2)CN. Firstly, we introduce the subgraph structure on the knowledge graph to capture high-order contextual information between users and items. Secondly, the mined subgraph information and graph convolutional network are combined to learn high-order features of users and items. Finally, the decoder is applied to predict the ratings of target users on the uninteracted items, thereby recommending the Top-K items. Experimental results on the Book-Crossing and *** datasets show that the proposed KG(2)CN obtains better performance in F1 score and AUC metrics.

The present study aims to evaluate customer satisfaction with the recommendation algorithm used by Netflix. Online streaming platforms have revolutionized the way people consume media content. With the multiplication of choices and the abundance of content, it has become difficult for users to find the materials they are interested in watching. To address this problem, recommendation algorithms have been developed to suggest the content that the user is most likely to find entertaining. The research is conducted through structural modeling equations and data analysis, with the use of data from 274 Netflix users. The results show a positive relationship between personalization, use of search engine, homepage usefulness and satisfaction from using Netflix’s recommendation algorithm. The results of this research contribute to our understanding of customer satisfaction with the recommendation system of online streaming platforms. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Existing short video content analysis methods often struggle with integrating multimodal data, resulting in incomplete content understanding and limited recommendation accuracy. To address these challenges, this study proposes a deep learning-based short video content analysis and recommendation algorithm that enhances feature extraction and personalization. CNN and LSTM are employed to automatically capture and extract multimodal features from short videos, generating a comprehensive feature representation through weighted fusion. Meanwhile, DNN is utilized to model user behavior, extracting deep behavioral features to enhance preference prediction. By jointly modeling video content and user behavior, a multimodal recommendation algorithm is developed to optimize content delivery. Experimental results show that, compared to CF, MF, and Content-Based Filtering benchmark algorithms, the proposed method improves average precision by 4.7%, 3.3%, and 4.0%, and recall by 3.5%, 1.2%, and 2.1%, respectively. These findings confirm that the deep learning-driven approach effectively enhances multimodal content understanding, meets personalized user preferences, and significantly improves recommendation accuracy, offering a more intelligent and adaptive short video recommendation framework.

In stock trading, a common phenomenon is that the trends of stocks in the same industry are very similar. In contrast, the movements of stocks in different industries are often different. Therefore, applying the same model to all stock trading is inappropriate without distinguishing the industries in which the stocks belong. However, recommending an optimal industry stock trading model is very challenging based on performance evaluation indicators. First, the indicators of the trading model are diverse. Second, the ranking of multiple indicators is often inconsistent. In the paper, we model the problem to be solved as a multi-criteria decision-making process. Therefore, we first divide stock dataset into nine industries according to their main business. Then, we apply several machine learning algorithms as candidate models to generate trading signals. Second, we conduct daily trading backtesting based on the trading signals to obtain multiple performance evaluation indicators. Third, we propose an optimal recommendation algorithm for the industry stock trading model with TODIM. The experimental results in the US stock market and China's A-share market show that the proposed algorithm can get a better trading model out-of-sample industry stock. Moreover, we effectively evaluate the generalization ability of the algorithm based on the proposed metrics. Finally, the proposed long-short portfolios based on the algorithm have achieved returns exceeding the benchmark on most out-of-sample datasets.

Recommender systems are one of the most im- portant technologies in e-commerce to help users filter out the overload of information. However, current mainstream recommendation algorithms, such as the collaborative filter- ing CF family, have problems ness. These problems hinder such as scalability and sparse- further developments of rec- ommender systems. We propose a new recommendation al- gorithm based on item quality and user rating preferences, which can significantly decrease the computing complexity. Besides, it is interpretable and works better when the data is sparse. Through extensive experiments on three benchmark data sets, we show that our algorithm achieves higher accu- racy in rating prediction compared with the traditional ap- proaches. Furthermore, the results also demonstrate that the problem of rating prediction depends strongly on item quality and user rating preferences, thus opens new paths for further study.
