A Learning-to-Rank Formulation of Clustering-Based Approximate Nearest Neighbor Search

1 code implementation17 Apr 2024 Thomas Vecchiato, Claudio Lucchese, Franco Maria Nardini, Sebastian Bruch

Its objective is to return a set of $k$ data points that are closest to a query point, with its accuracy measured by the proportion of exact nearest neighbors captured in the returned set.

Beyond Robustness: Resilience Verification of Tree-Based Classifiers

no code implementations5 Dec 2021 Stefano Calzavara, Lorenzo Cazzaro, Claudio Lucchese, Federico Marcuzzi, Salvatore Orlando

In this paper we criticize the robustness measure traditionally employed to assess the performance of machine learning models deployed in adversarial settings.

Learning Early Exit Strategies for Additive Ranking Ensembles

1 code implementation6 May 2021 Francesco Busolin, Claudio Lucchese, Franco Maria Nardini, Salvatore Orlando, Raffaele Perego, Salvatore Trani

Modern search engine ranking pipelines are commonly based on large machine-learned ensembles of regression trees.

Certifying Decision Trees Against Evasion Attacks by Program Analysis

no code implementations6 Jul 2020 Stefano Calzavara, Pietro Ferrara, Claudio Lucchese

Machine learning has proved invaluable for a range of different tasks, yet it also proved vulnerable to evasion attacks, i. e., maliciously crafted perturbations of input data designed to force mispredictions.

Query-level Early Exit for Additive Learning-to-Rank Ensembles

no code implementations30 Apr 2020 Claudio Lucchese, Franco Maria Nardini, Salvatore Orlando, Raffaele Perego, Salvatore Trani

In this paper, we investigate the novel problem of \textit{query-level early exiting}, aimed at deciding the profitability of early stopping the traversal of the ranking ensemble for all the candidate documents to be scored for a query, by simply returning a ranking based on the additive scores computed by a limited portion of the ensemble.

Treant: Training Evasion-Aware Decision Trees

1 code implementation2 Jul 2019 Stefano Calzavara, Claudio Lucchese, Gabriele Tolomei, Seyum Assefa Abebe, Salvatore Orlando

Despite its success and popularity, machine learning is now recognized as vulnerable to evasion attacks, i. e., carefully crafted perturbations of test inputs designed to force prediction errors.
