Masters and PhD Research Topics in Deep Learning for Big Data Analytics

Deep Learning and Big Data Analytics are two areas of data science that are receiving a lot of attention. Big Data has grown in importance as many public and commercial organizations have collected huge volumes of domain-specific information that can include helpful information concerning challenges such as national intelligence, cyber security, fraud detection, marketing, and medical informatics.

The primary objective of big data analytics is to extract useful patterns from the huge amount of data that can be used in decision-making and prediction. High storage capacities, high computation time, and increased accessibility of massive amounts of data are the reasons for the rise of big data analytics. Deep learning plays a powerful role in big data analytic solutions, which automatically extract complex features at a high level of abstraction from a large volume of data. The deep learning model can handle large amounts of data, real-time data, heterogeneous data, low-quality data, and big data feature learning characteristics.

In big data analytics, deep learning algorithms process data in real-time with high accuracy and efficiency. It uses supervised/unsupervised techniques to learn and extract data representations automatically. The typical deep learning models for big data analytics are stack autoencoders, deep belief networks, recurrent neural networks, and convolution neural networks.

Big Data Analytics is centered on mining and extracting significant patterns from enormous amounts of input data for decision-making, prediction, and other inferences. In addition to analyzing massive volumes of data, Big Data Analytics presents other special obstacles for machine learning and data analysis, such as raw data format variation, fast-moving streaming data, data analysis trustworthiness, noisy, poor quality data, high dimensionality, unbalanced input data, unsupervised and uncategorized data, limited labeled data etc. Other critical issues in Big Data Analytics include adequate data storage, indexing or tagging, and quick information retrieval. As a result, creative data analysis and data management solutions are required while working with big data.

Even though deep learning models have made great strides in big data analysis; however, their performances are not ideal on small or unbalanced datasets. Moreover, it demands further research involving data sampling for generating useful high-level abstractions, domain (data distribution) adaption, defining criteria for extracting good data representations for discriminative and indexing tasks, semi-supervised learning, and active learning.
