3D‐TabNetHS: A hyperspectral image classification method based on improved interpretable 3D attentive TabNet

IET Radar, Sonar & Navigation
The classification methods for hyperspectral images (HSI) based on decision trees and convolutional neural networks have shown increasing advantages, but these methods often require a large number of labelled samples for learning, which is difficult for ...

A Fully Autonomous On-Board GNC Methodology for Small-Body Environments Based on CNN Image Processing and MPCs

Aerospace
The increasing need for autonomy in space exploration missions is becoming more and more relevant in the design of missions to small bodies. The long communication latencies and sensitivity of the system to unplanned environmental perturbations mean ...

Symmetries of the gravitational scattering in the absence of peeling

Journal of High Energy Physics
The symmetries of the gravitational scattering are intimately tied to the symmetries which preserve asymptotic flatness at null infinity. In Penrose’s definition of asymptotic flatness, a central role is played by the notion of asymptotic simplicity and ...

Some Notes on Compact Sets in Soft Metric Spaces

, 2013
The first aim of this study is to define soft sequential compact metric spaces and to investigate some important theorems on soft sequential compact metric space. Second is to introduce net and totally bounded soft metric space and study properties of this space.

Dual-order evolution and adaptive geometric alignment via state spaces duality for few-shot action recognition

Journal of King Saud University: Computer and Information Sciences
Few-Shot Action Recognition (FSAR) enables rapid generalization with minimal annotations, yet existing approaches often struggle to balance computational efficiency with complex temporal modeling.

BEST APPROXIMATION IN SOFT METRIC SPACES

International Journal of Applied Mathematics
This article examines best approximation within soft metric spaces, a framework that effectively models uncertain and imprecise data. Extending classical best approximation theory, defining soft best approximation distance and establish theorem under soft contractive and cyclic contractive mappings in complete soft metric spaces.

Constant modulus algorithm aided soft decision directed scheme for blind space-time equalisation of SIMO channels

, 2007
This paper investigates a blind space–time equaliser (STE) designed for single-input multiple-output (SIMO) systems that employ high-throughput quadrature amplitude modulation schemes. A constant modulus algorithm (CMA) aided soft decision-directed (SDD)

Fault diagnosis of roadheader cutting heads based on frequency dynamic-aware and multi-view tree-structured topology

Meitan kexue jishu
As the primary equipment for roadway excavation, the roadheader operates under highly complex and variable working conditions, which makes the cutting head prone to faults.
