Exploiting Uncertainty for Querying Inconsistent Description Logics Knowledge Bases

no code implementations15 Jun 2023 Riccardo Zese, Evelina Lamma, Fabrizio Riguzzi

The necessity to manage inconsistency in Description Logics Knowledge Bases~(KBs) has come to the fore with the increasing importance gained by the Semantic Web, where information comes from different sources that constantly change their content and may contain contradictory descriptions when considered either alone or together.

Syntactic Requirements for Well-defined Hybrid Probabilistic Logic Programs

no code implementations17 Sep 2021 Damiano Azzolini, Fabrizio Riguzzi

Hybrid probabilistic logic programs can represent several scenarios thanks to the expressivity of Logic Programming extended with facts representing discrete and continuous distributions.

Nonground Abductive Logic Programming with Probabilistic Integrity Constraints

no code implementations6 Aug 2021 Elena Bellodi, Marco Gavanelli, Riccardo Zese, Evelina Lamma, Fabrizio Riguzzi

Uncertain information is being taken into account in an increasing number of application fields.

MAP Inference for Probabilistic Logic Programming

no code implementations4 Aug 2020 Elena Bellodi, Marco Alberti, Fabrizio Riguzzi, Riccardo Zese

In Probabilistic Logic Programming (PLP) the most commonly studied inference task is to compute the marginal probability of a query given a program.

Automatic Setting of DNN Hyper-Parameters by Mixing Bayesian Optimization and Tuning Rules

no code implementations3 Jun 2020 Michele Fraccaroli, Evelina Lamma, Fabrizio Riguzzi

The state-of-the-art hyper-parameters tuning methods are grid search, random search, and Bayesian Optimization.

Bayesian Optimization

Introduzione all'Intelligenza Artificiale

no code implementations13 Nov 2015 Fabrizio Riguzzi

The last part of the paper is devoted to the discussion ongoing among experts in the field and the public at large about on the advantages and disadvantages of AI and in particular on the possible dangers.

SWISH: SWI-Prolog for Sharing

1 code implementation3 Nov 2015 Jan Wielemaker, Torbjörn Lager, Fabrizio Riguzzi

Recently, we see a new type of interfaces for programmers based on web technology.

Lifted Variable Elimination for Probabilistic Logic Programming

no code implementations13 May 2014 Elena Bellodi, Evelina Lamma, Fabrizio Riguzzi, Vitor Santos Costa, Riccardo Zese

Lifted inference has been proposed for various probabilistic logical frameworks in order to compute the probability of queries in a time that depends on the size of the domains of the random variables rather than the number of instances.

Structure Learning of Probabilistic Logic Programs by Searching the Clause Space

no code implementations9 Sep 2013 Elena Bellodi, Fabrizio Riguzzi

It performs a beam search in the space of probabilistic clauses and a greedy search in the space of theories, using the log likelihood of the data as the guiding heuristics.
