Researchers teach computers how to name images by 'thinking'

Researchers have developed an AI system that enables computers to interpret images and provide accurate annotations, improving the accessibility of online image collections. The ALIPR system can automatically tag images with relevant keywords, facilitating search and retrieval, and has been shown to be correct in over 98% of cases.

High altitude broadband is the platform for the future

The CAPANINA project demonstrates how wireless and optical communications can be relayed from high-altitude platforms (HAPs) to bring low-cost broadband connections to remote areas. The system promises data rates 2,000 times faster than traditional modems, with applications ranging from disaster management to environmental monitoring.
