Deep Learning for Big Data Applications - Challenges and Future Directions

Yi Pan, Ph.D.
Regents' Professor and Chair
Department of Computer Science
Georgia State University
Atlanta, Georgia, USA

Due to improvements in mathematical formulas and increasingly powerful computers, we can now model many more layers of virtual neurons (deep neural networks or deep learning) than ever before. Deep learning is now producing many remarkable recent successes in computer vision, automatic speech recognition, natural language processing, audio recognition, and medical imaging processing. Although various deep learning architectures have been applied to many big data applications, extending deep learning into more complicated applications such as bioinformatics will require more conceptual and software breakthroughs, not to mention many more advances in processing power. In this talk, I will outline the challenges and problems in existing deep learning methods when applying it to big data in general and bioinformatics in particular. I will describe a few novel architectures and algorithms recently proposed by us to improve the accuracies and learning speeds of the existing deep learning technologies. These new deep learning architectures and algorithms will be applied to several big data applications including image processing, DNA sequence annotation, long intergenic non-coding RNA detection, and gene structure prediction. The data encoding schemes, the choice of architectures and methods used will be described in details. Performance comparisons with other machine learning and existing deep learning methods will be reported. The experimental results show that deep learning is very promising for many big data applications, but requires selection of suitable models and a lot of tuning to be effective. Future research directions in this exciting area will also be outlined.
