Abstract: Hierarchical Federated Learning (HFL) has emerged as a promising paradigm for distributed machine learning in edge computing environments. By introducing intermediate edge servers between ...

Locals claimed that around five to six massive pythons were entwined in the cluster.

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, ...

The sun wanders the Milky Way alone; our star orbits the galaxy’s distant center without any stellar siblings. But it wasn’t always this way. The solar system was very likely born in a tremendous gas ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

This project applies hierarchical clustering to group local authorities in England based on case closure reasons from the Children in Need Census (2013–2024). It supports benchmarking, policy ...

Abstract: Hierarchical clustering is a method in data mining and statistics used to build a hierarchy of clusters. Traditional hierarchical clustering relies on a measure of dissimilarity to combine ...

The hierarchical reasoning model (HRM) system is modeled on the way the human brain processes complex information, and it outperformed leading LLMs in a notoriously hard-to-beat benchmark. When you ...

Scientists have a good idea how stars should form in the central galaxies of rich clusters. The hot gas surrounding a cluster’s dominant innermost galaxy cools rapidly, sparking furious star formation ...
