Neither Black nor White: Balancing Semantic and Collaborative Signals with Graph-Informed Semantic IDs (GrIS)
Aleksei Medvedev, Alejandro Ariza-Casabona, Steven Derby +3
Existing work on Semantic IDs (SIDs) for generative recommendation treats SID construction as a representation learning problem: encode items into a quantised latent space and read…
Efficient Large-Scale Cross-Domain Sequential Recommendation with Dynamic State Representations
Manuel V. Loureiro, Steven Derby, Aleksei Medvedev +3
Recently, autoregressive recommendation models (ARMs), such as Meta's HSTU model, have emerged as a major breakthrough over traditional Deep Learning Recommendation Models (DLRMs),…
Universal Reusability in Recommender Systems: The Case for Dataset- and Task-Independent Frameworks
Tri Kurniawan Wijaya, Xinyang Shao, Gonzalo Fiz Pontiveros +1
Recommender systems are pivotal in delivering personalized experiences across industries, yet their adoption and scalability remain hindered by the need for extensive dataset- and…
STA: Self-controlled Text Augmentation for Improving Text Classifications
Congcong Wang, Gonzalo Fiz Pontiveros, Steven Derby +1
Despite recent advancements in Machine Learning, many tasks still involve working in low-data regimes which can make solving natural language problems difficult. Recently, a number…
Quantitative Metrics for Evaluating Explanations of Video DeepFake Detectors
Federico Baldassarre, Quentin Debard, Gonzalo Fiz Pontiveros +1
The proliferation of DeepFake technology is a rising challenge in today's society, owing to more powerful and accessible generation methods. To counter this, the research community…
Virtually fibering random right-angled Coxeter groups
Gonzalo Fiz Pontiveros, Roman Glebov, Ilan Karpas
We show that the Right-Angled Coxeter group associated to a random graph with virtual…
On the Ramsey number of the triangle and the cube
Gonzalo Fiz Pontiveros, Simon Griffiths, Robert Morris +2
The Ramsey number r(K_3,Q_n) is the smallest integer N such that every red-blue colouring of the edges of the complete graph K_N contains either a red n-dimensional hypercube, or a…
The triangle-free process and the Ramsey number
Gonzalo Fiz Pontiveros, Simon Griffiths, Robert Morris
The areas of Ramsey theory and random graphs have been closely linked ever since Erdős' famous proof in 1947 that the 'diagonal' Ramsey numbers grow exponentially in . In…
Sums of dilates in
Gonzalo Fiz Pontiveros
We consider the problem of sums of dilates in groups of prime order. We show that given of sufficiently small density then $$\big| λ_{1}A+λ_{2}A+...+ λ_{k}A \big|…
Freiman homomorphisms of random subsets of
Gonzalo Fiz Pontiveros
Let be a random subset of obtained by including each element of in independently with probability . We say that is \emph{linear} if…
