    Big Data and Causality
    (Springer, 2017-08-01) Hassani, Hossein; Huang, Xu; Ghodsi, Mansi
    Causality analysis continues to remain one of the fundamental research questions and the ultimate objective for a tremendous amount of scientific studies. In line with the rapid progress of science and technology, the age of big data has significantly influenced the causality analysis on various disciplines especially for the last decade due to the fact that the complexity and difficulty on identifying causality among big data has dramatically increased. Data mining, the process of uncovering hidden information from big data is now an important tool for causality analysis, and has been extensively exploited by scholars around the world. The primary aim of this paper is to provide a concise review of the causality analysis in big data. To this end the paper reviews recent significant applications of data mining techniques in causality analysis covering a substantial quantity of research to date, presented in chronological order with an overview table of data mining applications in causality analysis domain as a reference directory.

    Deep Learning and Implementations in Banking
    (Springer, 2020-06-29) Hassani, Hossein; Huang, Xu; Silva, Emmanuel; Ghodsi, Mansi
    Data-driven technologies have been changing every aspect of human life and the fast-developing banking sector with its data-rich nature has become the implementation field of these fast-evolving technologies. Deep learning, as one of the emerging technologies in recent years, has also been inevitably adopted for various improvements in banking. To the best of our knowledge, there is no comprehensive literature review, which focuses on specifically deep learning and its implementations in banking. Therefore, this paper investigates the deep learning technology in-depth and summarizes the relevant applications in banking so to contribute to the existing literature. Moreover, by providing a reliable and up-to-date review, it is also aimed to serve as the one-stop repository for banks and researchers who are interested in embracing deep learning, whilst bringing insights for the directions of future research and implementation.

    Is there a Causal Relationship between Oil Prices and Tourist Arrivals?
    (Taylor & Francis, 2020) Hassani, Hossein; Ghodsi, Mansi; Huang, Xu; Silva, Emmanuel
    This application note investigates the causal relationship between oil price and tourist arrivals to further explain the impact of oil price volatility on tourism related economic activities. The analysis itself considers the time domain, frequency domain and information theory domain perspectives. Data relating to the US and nine European countries are exploited in this paper with causality tests which include time domain, frequency domain, and Convergent Cross Mapping (CCM). The CCM approach is nonparametric and therefore not restricted by assumptions. We contribute to existing research through the successful and introductory application of an advanced method, and via the uncovering of significant causal links from oil prices to tourist arrivals. Keywords: Oil price; tourist arrivals; causality; convergent cross mapping; granger causality
