Considering spatiotemporal evolutionary information in dynamic multi‐objective optimisation
CAAI Transactions on Intelligence Technology, EarlyView., 2023 Abstract Preserving population diversity and providing knowledge, which are two core tasks in the dynamic multi‐objective optimisation (DMO), are challenging since the sampling space is time‐ and space‐varying. Therefore, the spatiotemporal property of evolutionary information needs to be considered in the DMO.

The impact of new millennium crises on the power of Islamic banks in deposit markets
International Journal of Finance &Economics, EarlyView.Abstract We investigate the impact of three crises on the power of Islamic banks in deposit markets: the Global Financial Crisis, 2007–2009 (GFC), the Arab Spring political crisis, 2011–2013, and the COVID‐19 health crisis, 2020–2022. Applying difference‐in‐difference (DID) and GMM techniques to panel data for 2004–2022, we find that the power of ...

Non-stationary Bandit Convex Optimization: A Comprehensive Study [PDF]
arXivBandit Convex Optimization is a fundamental class of sequential decision-making problems, where the learner selects actions from a continuous domain and observes a loss (but not its gradient) at only one point per round. We study this problem in non-stationary environments, and aim to minimize the regret under three standard measures of non ...

The impact of cryptocurrency heists on Bitcoin's market efficiency
International Journal of Finance &Economics, EarlyView.Abstract Within the adaptive market hypothesis (AMH) framework, this study explores the dynamic impact of cryptocurrency heists on Bitcoin's market efficiency. By analysing Bitcoin's one‐minute price data, we calculate permutation entropy to assess market disorder and employ the complexity‐entropy causality plane to quantify structural changes in the ...

International Journal of Finance &Economics, EarlyView.ABSTRACT This research aims to explore and understand the dynamic nature of volatility connectedness between BRICS stock markets and various asset price implied volatility indices through a TVP‐VAR broadened connectedness approach. Results display nontrivial dynamic connectedness in the BRICS stock markets and uncertainties in different markets during ...

Tracking Changing Probabilities via Dynamic Learners [PDF]
arXivConsider a predictor, a learner, whose input is a stream of discrete items. The predictor's task, at every time point, is probabilistic multiclass prediction, i.e. to predict which item may occur next by outputting zero or more candidate items, each with a probability, after which the actual item is revealed and the predictor updates.
