Intelligent Optimisation and the Bees Algorithm, Professor Duc Trong Pham

Abstract:
 
Many real-world engineering problems require the manipulation of a number of system variables in order to optimise a given quality parameter such as the reliability or accuracy of a process, or the cost or performance of a product. Optimisation will become even more important as resources diminish. When the number of variables is large, it can be difficult to locate the optimal solution.
 
The Bees Algorithm models the foraging behaviour of a swarm of honeybees in order to solve complex optimisation problems. The algorithm performs a combination of exploitative neighbourhood search and random explorative search. In this keynote speech, we will review different formulations of the Bees Algorithm together with other swarm-based optimisation algorithms and compare the effectiveness of the Bees Algorithm to that of three other biologically inspired search methods. We will review applications of the Bees Algorithm in engineering and manufacture and demonstrate its effectiveness at finding solutions to multi-modal optimisation problems.

Learning for Future Video, Professor Aggelos Katsaggelos

Abstract:

Learning has made it possible to unleash the power of data. We have moved away from the detailed modeling of a system or a phenomenon of interest thanks to the abundance of data as well as the huge improvements in processing power. With approaches like dictionary learning we can discover linear relationships between the input and output. On the other hand, recent advancements in deep learning have made it possible to discover non-linear relationships. As one of the examples in this talk we discuss the application of dictionary and deep learning to the video super-resolution problem. We describe a multiple-frame algorithm based on dictionary learning and motion estimation. We further describe the use of a convolutional neural network that is trained on both the spatial and temporal dimensions of videos to enhance their resolution. We demonstrate experimentally the effectiveness of these approaches. We finally discuss future research directions on the topic of learning.

Vision for Robotic Surgery, Guang-Zhong Yang

Abstract:

Robotic surgery is a rapidly developing field in recent years with recognised commercial growth and an increasing range of operations. This keynote lecture outlines major technical challenges, as well as new research opportunities in robotic surgery and how IWSSIP community can contribute towards its future advances, particularly in imaging and vision for intra-operative guidance. It will cover the latest developments in surgical robots and new applications of surgical vision, as well as the use of new imaging techniques for integrating cellular level information into in vivo, in situ tissue characterisation, functional assessment, and intraoperative guidance.

Recent Developments in SHM based on Time Series Analysis

Abstract:

Many of the algorithms used for Structural Health Monitoring (SHM) are based on or motivated by time series analysis. Quite often, detection methods are variants of approaches developed within the Statistical Process Control (SPC) community. Many of the algorithms used represent mature theory and have a rigorous probabilistic or mathematical basis. However, one of the main issues facing SHM practitioners is that the structures of interest rarely respect the assumptions inherent in deriving algorithms. In the case of time series data, SPC-based approaches usually require the data to be stationary and, unfortunately, SHM data is often nonstationary because of benign variations in the environment of the structure of interest, or because of deliberate operational changes in the use of the structure. This nonstationarity can manifest itself as slowly-varying trends on the data or in abrupt switches between regimes. Recent work in time series methods for SHM has made considerable progress in accommodating nonstationarity and some of that work is discussed within this presentation. Another issue in time series analysis is indirectly related to the assumption of linear behaviour of structures and the impact of this assumption is briefly considered in terms of its effects on detection thresholds in SPC-like methods; again, progress has been made recently. Some issues still remain, and these are discussed also.

Speaker Biography:

Professor Worden began academic life as a theoretical physicist, with a degree from York University and a PhD in Mechanical Engineering from Heriot-Watt University eventually followed. A period of research at Manchester University led to an appointment at the University of Sheffield in 1995, where he has happily remained since.

Keith's research is concerned with applications of advanced signal processing and machine learning methods to structural dynamics. The primary application is in the aerospace industry, although there has also been interaction with ground transport and offshore industries.

One of the research themes concerns non-linear systems. The research conducted here is concerned with assessing the importance of non-linear modelling within a given context and formulating appropriate methods of analysis. The analysis of non-linear systems can range from the fairly pragmatic to the extremes of mathematical complexity. The emphasis within the research group here is on the pragmatic and every attempt is made to maintain contact with engineering necessity.

Another major activity within the research group concerns structural health monitoring for aerospace systems and structures. The research is concerned with developing automated systems for inspection and diagnosis, with a view to reducing the cost-of-ownership of these high integrity structures. The methods used are largely adapted from pattern recognition and machine learning; often the algorithms make use of biological concepts e.g. neural networks, genetic algorithms and ant-colony metaphors. The experimental approaches developed range from global inspection using vibration analysis to local monitoring using ultrasound.
