Opportunities arise to carry out postgraduate research towards an MPhil / PhD in the areas identified below. Fully-funded Nottingham Trent University PhD studentships are available. For more information please contact by email.
- Area 1: Machine learning using electronic health records to select high-risk patients
- Area 2: Deep learning for anomaly traffic detection in Internet of Things devices
Highlights of his research work:
- Introduced drift analysis to theoretical analysis of evolutionary algorithms. 'Drift analysis was introduced to the theory of evolutionary algorithms by He and Yao. It soon became one of the strongest tools both for proving run-time guarantees for many evolutionary algorithms and for giving evidence that some algorithms cannot solve certain problems.' 'drift analysis, a method that provided important insights into the computational complexity of discrete EAs over the last decade.' 'drift analysis, a standard tool in theory of randomised search heuristics'
- Designed helper and equivalent objective differential evolution for constrained optimization (HECO-DE), ranked 1st in 2019 in IEEE CEC Competition on Constrained Real Parameter Optimization.
- Proposed average convergence rate of evolutionary algorithms. 'The fourth type of convergence representation is the average convergence rate that specifically measures the rate of fitness change as proposed by He and Lin.' 'Convergence ratio can be evaluated by Markov chain analysis, however, this process is complicated from theoretical and practical point of view. For this reason, the convergence indicator is described as (He and Lin, 2016).'
- Rigorously analysed easiest and hardest functions to evolutionary algorithms. 'The theory indicates easy problems for one algorithm may be difficult for another, and vice versa.' 'This further explains RSHs (randomized search heuristics) are not always efficient for all problems.'
