kANNolo: Sweet and Smooth Approximate k-Nearest Neighbors Search

Leonardo Delfino, Domenico Erriquez, Silvio Martinico +3

Approximate Nearest Neighbors (ANN) search is a crucial task in several applications like recommender systems and information retrieval. Current state-of-the-art ANN libraries, alt…

Early-Exit Graph Neural Networks

Andrea Giuseppe Di Francesco, Maria Sofia Bucarelli, Franco Maria Nardini +3

Early-exit mechanisms allow deep neural networks to stop inference once prediction confidence is high, reducing latency and energy on easy inputs while retaining full-depth accurac…

Multivector Reranking in the Era of Strong First-Stage Retrievers

Silvio Martinico, Franco Maria Nardini, Cosimo Rulli +1

Learned multivector representations power modern search systems with strong retrieval effectiveness, but their real-world use is limited by the high cost of exhaustive token-level…
