Machine Learning Techniques for Big Data Analytics: A Comprehensive Survey

A new study on data security is now available, presented by researchers at Khalifa University. The research provides a comprehensive survey and experimental evaluation of machine learning techniques for Big Data Analytics across four critical domains: IoT, Social Media, Natural Language Processing (NLP), and Information Security. The study integrates large-scale experimental benchmarking of key techniques, including CNN, XGBoost, Self-Supervised Learning (SSL), Graph Neural Networks (GNN), ELM, KNN, and Decision Trees, using real-world and synthetic datasets. The research concludes that machine learning techniques can be effective in Big Data Analytics, but their suitability depends on the specific domain and task.

Key Takeaways:

  • The study introduces a novel taxonomic framework to classify and analyze the suitability of algorithms based on empirical, experimental, and computational perspectives.
  • GNN and Self-Supervised Learning (SSL) are top performers in terms of predictive performance and efficiency in domains such as IoT and Social Media.
  • XGBoost and CNN offer superior accuracy and robustness across structured and unstructured data tasks, though CNN incurs higher computational costs.
  • ELM and Decision Trees are better suited for lightweight or interpretable applications.
  • KNN generally underperforms in scalability and predictive strength for large-scale tasks.
  • The taxonomy and experiments collectively demonstrate the need for context-aware algorithm selection, particularly for real-time and scalable Big Data applications.
  • Researchers and practitioners seeking effective analytic strategies in the evolving landscape of Big Data can benefit from the actionable insights provided by this study.
  • The study uses real-world and synthetic datasets to evaluate the performance of various machine learning techniques.

Statistics:

  • The study integrates large-scale experimental benchmarking of 7 key techniques using real-world and synthetic datasets.
  • The techniques evaluated include CNN, XGBoost, SSL, GNN, ELM, KNN, and Decision Trees.
  • The study evaluates the techniques across 5 performance metrics: accuracy, F1-score, precision, recall, and computational time.
