Hybrid Sparrow Clustered (HSC) Algorithm for Top-N Recommendation System

Abstract

Recommendation systems suggest relevant items to a user based on the similarity between users or between items. In a collaborative filtering approach for generating recommendations, there is a symmetry between the users. That is, if user A has similar interests with user B, then an item liked by B can be recommended to A and vice versa. To provide optimal and fast recommendations, a recommender system may generate and keep clusters of existing users/items. In this research work, a hybrid sparrow clustered (HSC) recommender system is developed, and is applied to the MovieLens dataset to demonstrate its effectiveness and efficiency. The proposed method (HSC) is also compared to other methods, and the results are compared. Precision, mean absolute error, recall, and accuracy metrics were used to figure out how well the movie recommender system worked for the HSC collaborative movie recommender system. The results of the experiment on the MovieLens dataset show that the proposed method is quite promising when it comes to scalability, performance, and personalized movie recommendations.

The Application of Personalized Recommendation System in the Cross-Regional Promotion of Provincial Intangible Cultural Heritage

“…(3) Literature [21] calculates the UICPR matrix by calculating the priority ratio of user item categories to reduce the dimension of data. Meanwhile, users are clustered, and the closest users are found so as to obtain the predicted rating and make recommendations (4) Literature [22] Literature [20] Literature [21] Literature [22] Proposed Mae value…”

A Systematic Survey on Energy-Efficient Techniques in Sustainable Cloud Computing

“…All strategies used to lower energy-specific hardware components/levels are covered in extreme detail. There is much emphasis on techniques deployed at the hardware-level (network-or server-level) that can lead to energy-efficient or ecologically friendly data centers [122][123][124][125][126][127][128][129][130][131][132].…”

“…A hypervisor is the system software that works as an operating system (abstraction layer) for virtual machines and coordinates with the underlying hardware components according to the virtual machine's predefined instructions [124][125][126][127]. Virtualization is not a new concept in the IT sector as it has already been implemented with our grand old Main Frames, which belong to second-generation computing devices.…”

A Novel Deep Learning-Based Cooperative Communication Channel Model for Wireless Underground Sensor Networks

“…Finally, the path discovery decision module includes a traffic method-based method [40,41]. A DL neural network is used in the routing selection module to acquire sufficient knowledge from the information collection domain and receive environmental monitoring attributes using DL neural networks [29].…”

“…DLAE is responsible for estimating the underground dynamic condition through information in the approach [28]. Local storage package query information needs to be gathered and sent to the server by the sink nodes [29]. The previous information will also be examined in the input layers by the analytics system during the test process.…”
