Speech Title: On Cluster Based Multivariate Outlier Detection in Data Mining

Abstract: In today’s big data age, mining outliers has become more and more important. It has wide applications in many fields, such as, detection of potential terrorist attacks, credit card fraud detection, network intrusion, clinical trials, severe weather prediction, and athlete performance analysis. On the other side, outlier removal also plays an important role in big data cleaning process. In this study, we propose a normal mixture model for the multivariate outlier detection. Due to the large volume and variety of big data, the classical Euclidean distance measure are not working well for mining multivariate outliers. Variables among different dimensions are usually correlated. Different distant measures will be discussed including the well-known Mahalanobis distance. The mixture model parameters are fitted via the EM algorithm. The K-means clustering algorithm is used to provide the initial inputs for the EM algorithm. The optimal k clusters and initial centers issues will be discussed. A nonsingular robust covariance estimation in calculating Mahalanobis distance will be introduce.

Speech Title: Understanding the Use and Impact of Big Data and Analytics: Research Challenges and Opportunities
Abstract: The emergence of Big Data and the advance of analytical technologies provide organisations with extraordinary opportunities to differentiate themselves through analytics. How, why and to what extent is Big Data and Analytics impacting on business operations and performance? Researchers are facing many emerging research challenges as well as opportunities in order to address these questions and to help organisations maximise the value of analytics in the era of Big Data. This presentation will first provide a brief review of the current development of research on understanding of the use and impact of Big Data Analytics. Based on the speaker’s involvement in the research projects focusing on examining the impact of analytics on business competitive advantages, innovation, strategic decision making, and student experience management in UK HEIs, the presentation will discuss the practical implications for industry and the key challenges and opportunities for research emerged from the recent research projects.

Speech Title: Impacts of introducing index futures on stock market volatilities: New evidences from China

Abstract: Two index futures, the SSE 50 futures (IH) and the CSI 300 futures (IC), respectively underlying big blue chips and medium-small stocks indexes, were launched on the same day of Apr 2015 in China. However, due to the stock market crash they were strictly restrained four months later. This paper examines how the introductions of IH and IC affect their corresponding stock volatilities, by adopting Hsiao et al. (2012)'s panel data evaluation approach. Results show that IH significantly reduces the spot volatility before (after) the crash, but its function is significantly weakened during the crash. For IC, it always fails to stabilize the spot market and even largely magnifies the volatility during (after) the crash. Further studies give evidence that such different intervention effects on the two markets might be attributed to the different characteristics of their constituent stocks, in particular their different levels of speculative activities.

Speech Title: A self-adaptive bat algorithm for the truck and trailer routing problem

Abstract: The truck and trailer routing problem (TTRP) which is one of the important NP-hard combinatorial optimization problems due to its multiple real-world applications. It is a generalization of the famous vehicle routing problem (VRP), involving a group of geographically scattered customers served by the vehicle fleet including trucks and trailers. In this study, we propose a meta-heuristic solution approach based on bat algorithm (BA) in which a local search procedure performed by five different neighborhood structures is developed. Moreover, a self-adaptive (SA) tuning strategy to preserve the swarm diversity is implemented. The effectiveness of the proposed SA-BA is investigated by an experiment conducted on 21 benchmark problems that are well known in the literature.

Speech Title: Dynamic Micro-Mechanism of Breakthrough Inventions Based on Multilevel Knowledge Networks
Abstract: China has become a major patent nation, but not a strong innovation nation, as indicated by the lack of breakthrough inventions (BI’s). In order to increase the productivity of BI’s, we have to understand their mechanism, especially the dynamic and micro processes on individual and team levels. We tackle this problem by integrating invention-problem specific knowledge, individual knowledge, team knowledge and global knowledge in a multilevel knowledge network.  Breakthrough inventions can then be modeled as the dynamic searching, learning and recombining operations of the multilevel knowledge network.  We design methods for constructing such multilevel knowledge networks, propose building network models for the mental processes, inventive schemes and thinking methods of breakthrough inventors’, modeling dynamic micro-mechanism of breakthrough inventions and verifying the model by patent analysis and multi-agent simulation.
