He has been invited to give 70+ keynote/plenary speeches at international conferences. His major research interests include evolutionary computation and neural network ensembles. 


Abstract:


Previous work on evolving neural networks has focused on single neural networks. However, monolithic neural networks have become too complex to trainand evolve for large and complex problems. It is often better to design acollection of simpler neural networks that work collectively and cooperatively to solve a large and complex problem. The key issue here is how to design such a collection, i.e., an ensemble, automatically so that it has the best generalisation ability. This talk first reviews briefly early work on evolving neural networks. Then a previous idea of designing ensembles, negative correlation learning, is explained. Lastly, several recent studies are introduced, which analyze the impact of diversity on online ensemble learning and that on multi-class class imbalance learning. The ideas behind some new ensemble algorithms for online learning, class imbalance learning, and online class imbalance learning will be presented. Applications of such new ensemble learning algorithms will also be mentioned and future research directions discussed.

Title: Single Frame Super Resolution: A Fuzzy Rule-Based Approach

Abstract:


High quality image zooming is an important problem. There are many methods that use multiple low resolution (LR) frames of the same scene with different sub-pixel shifts as input to generate the high resolution (HR) images. Now a days single frame super resolution (SR) methods that use just one LR image to obtain the HR image is gaining popularity.  In this talk we shall discuss a novel fuzzy rule based single frame super resolution method. This is a patch based method, where each LR patch is replaced by a HR patch generated by Takagi-Sugeno type fuzzy rules. We shall discuss in details the generations of the training data, the initial generation of the fuzzy rules, their refinement and how to use the rules for generation of SR images. In this context we shall also develop a Gaussian Mixture Regression (GMR) model for the same problem. Comparison of performance of the fuzzy rule-based  system with five existing methods as well as with the GMR method in terms of the three quality criteria demonstrates the superior performance of the  fuzzy rule-based system.

Abstract:


The field of Artificial Intelligence (AI) has seen stages of stagnation followed by tipping points all over its history. Be it in natural language processing/understanding, neural networks, fuzzy systems, or evolutionary computation, these tipping points marked real advances in AI. Today, AI is getting closer and closer to a new tipping point. However, it is a tipping point of a different kind; one with orders of magnitude more significance than any previous one. The age of the human brain project, the era of big data and models, the advances in computational science, the revolution in hardware and sensors, and the success stories made by computational intelligence researchers are all converging to generate this tipping point. 
In this presentation, the audience will get to see some early signs of the next generation AI systems. Red teaming is the science and art of role-playing an opponent. In this talk, the first of its kind Computational Red Teaming (CRT) system that was able to autonomously red team against humans will be demonstrated. The system integrates Encephalographic (EEG) data (brain signals) with performance metrics and the operational environment to red team with humans. The talk will demonstrate that the next generation AI system, where the biological brain is seamlessly integrated with in-Silico brain, is just at our doorsteps!
