Machine- and deep-learning-driven angular momentum inference from BHEX observations of the $n=1$ photon ring

Autor: Farah, Joseph R., Davelaar, Jordy, Palumbo, Daniel, Johnson, Michael D., Delgado, Jonathan

The $n=1$ photon ring is an important probe of black hole (BH) properties and will be resolved by the Black Hole Explorer (BHEX) for the first time. However, extraction of black hole parameters from observations of the $n=1$ subring is not trivial. D

Bridging Search and Recommendation in Generative Retrieval: Does One Task Help the Other?

Autor: Penha, Gustavo, Vardasbi, Ali, Palumbo, Enrico, de Nadai, Marco, Bouchard, Hugues

Generative retrieval for search and recommendation is a promising paradigm for retrieving items, offering an alternative to traditional methods that depend on external indexes and nearest-neighbor searches. Instead, generative models directly associa

From Logits to Hierarchies: Hierarchical Clustering made Simple

Autor: Palumbo, Emanuele, Vandenhirtz, Moritz, Ryser, Alain, Daunhawer, Imant, Vogt, Julia E.

The structure of many real-world datasets is intrinsically hierarchical, making the modeling of such hierarchies a critical objective in both unsupervised and supervised machine learning. Recently, novel approaches for hierarchical clustering with de

Planet formation is strongly influenced by the composition and distribution of volatiles within protoplanetary disks. With JWST, it is now possible to obtain direct observational constraints on disk ices, as recently demonstrated by the detection of
