Training Over a Distribution of Hyperparameters for Enhanced Performance and Adaptability on Imbalanced Classification

Autor: Lieberman, Kelsey, Ravindran, Swarna Kamlam, Yuan, Shuai, Tomasi, Carlo

Although binary classification is a well-studied problem, training reliable classifiers under severe class imbalance remains a challenge. Recent techniques mitigate the ill effects of imbalance on training by modifying the loss functions or optimizat

Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial $B$-mode power spectrum of the Cosmic Microwave Background (CMB). Since this proposed measurement is about three to four orders of magnitude fainter t

Structuring Authenticity Assessments on Historical Documents using LLMs

Autor: Schimmenti, Andrea, Pasqual, Valentina, Tomasi, Francesca, Vitali, Fabio, van Erp, Marieke

Given the wide use of forgery throughout history, scholars have and are continuously engaged in assessing the authenticity of historical documents. However, online catalogues merely offer descriptive metadata for these documents, relegating discussio
