Analysis of the Application of Machine Learning Algorithm in Spam Detection System: Literature Review

Abstract

Spam detection is an evolving issue in line with the increasing volume of data and the evolution of spam techniques. In recent years, the application of machine learning (ML) algorithms has become an effective solution to enhance the accuracy and efficiency of spam detection systems. This study aims to analyze various machine learning algorithms applied in spam detection systems through a literature review. Several popular algorithms used in spam detection include Naive Bayes, Support Vector Machine (SVM), Neural Network, Recurrent Neural Network (RNN), and Transformer-based models. Each algorithm has its strengths and weaknesses that affect its performance in handling spam detection issues, depending on the characteristics of the data and the application requirements. Based on the data obtained, the Naive Bayes algorithm achieved 88% accuracy, 85% precision, 90% recall, and 87% F1-score. In contrast, SVM showed higher results with 93% accuracy, 92% precision, 94% recall, and 93% F1-score. Neural Network reached 96% accuracy, 95% precision, 97% recall, and 96% F1-score, while Recurrent Neural Network (RNN) achieved 95% accuracy, 94% precision, 96% recall, and 95% F1-score. Transformer-based models provided the best results with 97% accuracy, 96% precision, 98% recall, and 97% F1-score. This study adopts a literature analysis method by reviewing various articles and research that discuss the application of these algorithms in spam detection. In conclusion, the selection of the appropriate algorithm should be adjusted to the characteristics of the dataset, the complexity of the problem, and the availability of computational resources, as each algorithm has its own strengths and weaknesses in the context of spam detection.
