Harmony Search Variants and Their Application to Engineering Problems

Abstract

Among optimization methods, metaheuristic algorithms have shown their capabilities for finding the near-optimal solution for which analytical methods may not be able to produce an acceptable solution within a reasonable computation time, especially when the global optimum is surrounded by many local optima. Therefore, the need of using these approaches is understood by the optimization community.
The Harmony Search (HS), published in 2001, is derived from the concepts of musical improvisations and harmony knowledge, and is considered as one of the well-known metaheuristic algorithms. So far, the HS has proved its advantages over other optimizers and there are many improved variations of the HS in the literature. In recent years, it has become obvious that the concentration on a sole optimization method is rather restrictive. A skilled combination of concepts from different optimizers can provide more efficient results and a higher flexibility when dealing with large-scale problems, especially with large scale engineering problems.
This keynote speech will first introduce the concept of Harmony Search and the potential abilities of its variants including improved and/or hybridized versions. In addition, applications to some typical engineering problems will be discussed along with the results.

Prof. Ajit Kumar Verma
A Computational Intelligence Framework for Optimal Maintenance of Large Engineering Systems

Abstract

Maintenance Optimization for Large Engineering Systems is a key area in asset management. Machinery Health Monitoring is increasingly being adopted by industries not only as a means for asset management but also for ensuring high levels of vailability with its consequent gains by ascertaining the impact in enhancing availability at plant level and in a cost effective manner. Quantification of certain features such as detect-ability and prognostic ability and a  fuzzy logic approach for doing so are presented. These features are then incorporated in a multi-objective maintenance optimization model based on Markov process and genetic algorithm, the results of which serve as decision support system for the selection of health monitoring. A demonstrative  case is presented to illustrate this idea.

Dr. Veena Mendiratta
Anomaly Detection in Wireless Networks using Mobile Phone Data

Abstract

Communications traffic on wireless networks generates large volumes of metadata on a continuous basis across the various servers involved in the communication session. Since these networks are engineered for high reliability, the data is predominantly normal with only a small proportion of the data being anomalous. It is, however, important to detect these anomalies when they occur because such anomalies are indicators of vulnerabilities in the network. In this talk we will present: non-parametric methods for anomaly detection, and the use of neural network based Kohonen Self Organizing Maps (SOM) and visual analytics for network anomaly detection and analysis using data from a 4G wireless network.

Dr. Seyedali Mirjalili
Confidence-based robust optimisation

Abstract

Robust optimisation refers to the process of combining good performance with low sensitivity to possible perturbations. Due to the presence of different uncertainties when optimising real problems, failure to employ robust optimisation techniques may result in finding unreliable solutions. Robust optimisation techniques play key roles in finding reliable solutions when considering possible uncertainties during optimisation.
Evolutionary optimisation algorithms have become very popular for solving real problems in science and industry mainly due to simplicity, gradient-free mechanism, and flexibility. Such techniques have been employed widely as very reliable alternatives to mathematical optimisation approaches for tackling difficulties of real search spaces such as constraints, local optima, multiple objectives, and uncertainties. Despite the advances in considering the first three difficulties in the literature, there is significant room for further improvements in the area of robust optimisation, especially combined with multi-objective approaches.
In this talk, a brief discussion on preliminaries and key concepts of robust optimisation will be given first. The essential components of a systematic robust optimisation algorithm design process are then presented. Finally, the newly emerged confidence-based robust optimisation perspective will be discussed to find robust optimal solutions for engineering design problems with expensive objective functions. The talk will focus on both single and multi-objective robust optimisations. Also, a real application of the confidence-based robust multi-objective optimisation will be introduced as a practical demonstration.

Dr. R. N. Mohapatra
Correlation Pattern Recognition

Abstract

Filters are very useful in signal analysis. We have seen high pass and low pass filters and wavelet filter banks etc. . Correlation filter theory relies heavily on concepts and tools from the fields of linear algebra and probability theory. Matrices and vectors provide succinct methods of expressing operations on discrete images, manipulating multiple variables and optimizing multiple parameters. In this talk we will introduce the notion of correlation filters and quadratic filters for pattern recognition, face recognition and its other applications. It is an interesting topic where mathematicians, statisticians and engineers can find avenues for new research. We will demonstrate the results of a case study associated with automatic pattern recognition.
