Title of Speech: Pruning Deep Learning Models

Abstract: Advances in deep learning have started a new AI revolution that is transforming our world. Applications in speech recognition, self-driving cars and publicity around systems such Alpha Go defeating human Go champions has ignited interest from the public, academia and industry. Convolutional neural networks, that can take images as input, learn to identify key features and perform classification are the heart of many of the proposed applications in medical diagnosis such as detecting breast cancer, predicting Alzheimer’s disease and grading brain tumours. These neural networks can, however, be very large, taking up memory and requiring significant computational resources. For example, one of the most highly cited networks, AlexNet has over 62 million parameters that need to be learned. Hence, this keynote explores methods for reducing the size of such networks without compromising performance. The talk will summarise existing methods for pruning neural networks, including direct methods, and Optimal Brain Damage, and describe our recent work on a new framework, based on the use of multi-armed bandits such as Thomson Sampling and Upper Confidence Bounds. The talk will conclude with the results of an empirical evaluation of the new methods over several benchmark data sets such as ImageNet, MNIST, CIFAR and Street View House Numbers.

Title of Speech: Synchronization of Biological Oscillators

Abstract: The collective behavior of biological and chemical oscillators is a fascinating topic that has attracted a lot of attention in the last 50 years. The integrate-and-fire model of the cardiac pacemaker was developed by C. Peskin to a population of identical pulse-coupled oscillators. It was conjectured that the model self-synchronizes such that: (C1) For arbitrary initial conditions, the system approaches a state in which all the oscillators are firing synchronously. (C2) This remains true even when the oscillators are not quite identical. The conjecture (C1) is solved by C. Peskin for a system with two oscillators, and R. Mirollo and S. Strogatz for the generalized model of two and more oscillators. In the present research we give a solution of the conjecture (C2). A new way of analysis that can be employed to solve many interesting problems is proposed. All results are derived for the most general setting. The talk will consists of main results, simulations and discussion of possible extensions. Applications for neural networks are discussed.

Title of Speech: Seeing Beneath the Soil with GPR

Abstract: Ground Penetrating Radar (GPR) is the general term applied to techniques which employ radio waves, typically in the MHz and GHz range, to map structures and features buried in the ground or in man-made structures. Currently, GPR surveys include on-site GPR measurements followed by an interactive use of geophysics or image processing packages and interpretation of obtained results by skilful and experienced human GPR operator. Subtleties in processing and interpretation of GPR data mean that surveyors and GPR data analysts may often fail to detect targets that could otherwise be clearly resolved. GPR measurements can suffer from excessive amount of noise or clutter making them extremely difficult to understand and interpret, even to well-trained and skilful GPR operators. Current research in this field focuses on improving GPR hardware but even more so on developing and advancing techniques for GPR image processing and analysis using modern machine vision and artificial intelligence algorithms and techniques. This talk will introduce GPR technology and expose some issues related to the use of this technology in engineering as well as in some other areas of human activity. GPR capabilities, some problems and developments in the field will be discussed with particular focus on the use of signal and image processing techniques for the analysis of GPR data and images acquired through simulations and real measurements.
