A Bridge Transformer Network With Deep Graph Convolution for Hyperspectral Image Classification

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Transformers have been widely applied to hyperspectral image classification, leveraging their self‐attention mechanism for powerful global modelling. However, two key challenges remain as follows: excessive memory and computational costs from calculating correlations between all tokens (especially as image size or spectral bands increase) and ...

Cohesion Policy and Institutional Quality Impact: Does Urban–Rural Classification Matter?

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This study examines the impact of Cohesion Policy, and institutional quality, on regional economic performance across NUTS2 regions in 27 EU member states from 2007 to 2022. Average per capita Cohesion Policy payments are much higher in less developed regions, showing the policy focus on supporting lagging areas.
