The paper explores the application of Deep Learning in Big Data Analytics, highlighting its potential to address complex problems such as extracting patterns from large volumes of data, semantic indexing, data tagging, fast information retrieval, and discriminative tasks. Deep Learning algorithms, with their hierarchical learning process, are particularly effective in handling unsupervised data, making them valuable for Big Data Analytics. The authors discuss the benefits of Deep Learning, including the ability to learn high-level abstractions and the efficiency of using simpler linear models for tasks like classification and prediction. They also address specific challenges in Big Data Analytics, such as streaming data, high-dimensional data, scalability, and distributed computing, and propose future research directions, including data sampling, domain adaptation, and active learning. The paper concludes by emphasizing the need for further innovation in Deep Learning to fully leverage its potential in Big Data Analytics.The paper explores the application of Deep Learning in Big Data Analytics, highlighting its potential to address complex problems such as extracting patterns from large volumes of data, semantic indexing, data tagging, fast information retrieval, and discriminative tasks.
