An approach to curves in abelian surfaces using Fourier--Mukai and quadratic forms
Katrina Honigs, Graham McDonald, Peter M. McDonald
It was proven by Yoshioka that given a complex abelian surface of Picard rank whose primitive polarization is non-principal of type , there is an isomorphism $Ψ:\mat…
Explaining When PRF Fails: Participatory Auditing for Selective Query Expansion
Zeyan Liang, Graham McDonald, Iadh Ounis
The paper investigates why pseudo-relevance feedback (PRF) harms many queries and introduces a two‑stage audit‑then‑automate framework that uses user audits and LLM‑based rerankers…
Document Similarity Enhanced IPS Estimation for Unbiased Learning to Rank
Zeyan Liang, Graham McDonald, Iadh Ounis
Learning to Rank (LTR) models learn from historical user interactions, such as user clicks. However, there is an inherent bias in the clicks of users due to position bias, i.e., us…
Quantifying Query Fairness Under Unawareness
Thomas Jaenich, Alejandro Moreo, Alessandro Fabris +4
Traditional ranking algorithms are designed to retrieve the most relevant items for a user's query, but they often inherit biases from data that can unfairly disadvantage vulnerabl…
Theta characteristics and the fixed locus of [-1] on some varieties of Kummer type
Katrina Honigs, Graham McDonald
We study some combinatorial aspects of the fixed loci of symplectic involutions acting on hyperkähler varieties of Kummer type. Given an abelian surface with a -polariz…
