Enhancing Generalisation via Cascaded Inertia SGD With Learnt Hyperparameters
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT A central challenge in deep learning lies in achieving strong model generalisation, an area in which conventional optimisers such as stochastic gradient descent (SGD) often exhibit limitations, even though they ensure convergence. This paper introduces cascaded inertia SGD (CISGD), a novel optimisation algorithm specifically designed to ...

A Quantised Push‐Sum Distributed Adaptive Momentum Algorithm for Optimisation Over Directed Networks
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT In this paper, we investigate a distributed constrained optimisation problem over directed networks. The agents in the networks conduct local computations and communications, endeavouring to collaboratively minimise the aggregation of all locally known convex cost functions subject to a global constraint set.

CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

High Voltage, EarlyView.ABSTRACT Moisture is a sensitive issue for transformer oils, as it adversely affects the stability of insulation papers and dielectric strength of the oils. However, the lack of a quantitative model makes it challenging to evaluate the water solubility of ester‐based oils, which is an undesirable restriction for developing novel ester‐based oils ...

800 kV Fast Circuit Breaker: Mechanical Coupling Modelling, Buffer Design and Development
High Voltage, EarlyView.ABSTRACT The 800 kV fast circuit breaker (CB) used in ultra‐high voltage (UHV) converter transformer can reduce the total breaking time to 25 ms. It significantly improves the action speed and breaking capacity of the CB, with promising broad application prospects.
