📖 Competition Description Domain Background arXiv.org is one of the world’s largest open-access repositories of scientific papers, with millions of submissions spanning disciplines such as computer science, mathematics, physics, and beyond. However, with the continuous growth of submissions, automated classification of research papers has become an important task to help researchers and librarians organize and retrieve knowledge efficiently. Problem Statement In this competition, your goal is to predict the research category of an arXiv paper given its metadata. Each paper is represented by an ID and a label corresponding to its main subject category (e.g., cs.CL, math.CO, physics.optics, etc.). This is a multi-class text classification problem, where your model must map each paper ID in the test set to its most likely research field.
