AI‐Powered Anomaly Detection for Secure Internet of Things (IoT): Optimising XGBoost and Deep Learning With Bayesian Optimisation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Intelligent and adaptive defence systems that can quickly thwart changing cyberthreats are becoming more and more necessary in the dynamic and data‐intensive Internet of things (IoT) environment. Using the NSL‐KDD benchmark dataset, this paper presents an improved anomaly detection system that combines an optimised sequential neural network ...

Dynamic Facial Expression Recognition of Learners via Adaptive Global Attention and Differential Temporal Transformer

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Analysing learners' facial expressions during learning and exploring their learning processes and emotional changes are of great significance for assisting teachers' teaching and promoting smart education. In complex learning environments, static facial expression recognition fails to capture the dynamic changes of learners' expressions losing

Progressive Colour Equalisation and Detail Refinement for Underwater Image Enhancement

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Underwater image enhancement remains a critical challenge in computational vision due to complex distortions caused by wavelength‐dependent light absorption and scattering. This paper introduces CEDFNet, a novel two‐stage framework that leverages advanced computational intelligence techniques for robust and high‐fidelity underwater image ...

Investigating the Effects of Environmental Uncertainty, Business Strategy and Management Control Systems on Organisational Learning and Performance

open access: yesAccounting &Finance, EarlyView.
ABSTRACT This study investigates the effects of environmental uncertainty, business strategy and management control systems on organisational learning and business performance. This study finds that environmental uncertainty is positively related to the intensity of the product differentiation strategy, and the intensity of the product differentiation ...

The oscillatory response of the electroretinogram and neuronal adaptation

open access: yesActa Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.
