NLPGuard: A Framework for Mitigating the Use of Protected Attributes by NLP Classifiers

no code implementations1 Jul 2024 Salvatore Greco, Ke Zhou, Licia Capra, Tania Cerquitelli, Daniele Quercia

AI regulations are expected to prohibit machine learning models from using sensitive attributes during training.

Unsupervised Concept Drift Detection from Deep Learning Representations in Real-time

1 code implementation24 Jun 2024 Salvatore Greco, Bartolomeo Vacchetti, Daniele Apiletti, Tania Cerquitelli

Concept Drift is a phenomenon in which the underlying data distribution and statistical properties of a target domain change over time, leading to a degradation of the model's performance.

Representation of preferences for multiple criteria decision aiding in a new seven-valued logic

no code implementations31 May 2024 Salvatore Greco, Roman Słowiński

To this end, we present a specific procedure to construct a seven-valued preference relation and use it to define recommendations that consider robustness concerns by utilizing multiple outranking or value functions representing the decision maker s preferences.

FRRI: a novel algorithm for fuzzy-rough rule induction

no code implementations7 Mar 2024 Henri Bollaert, Marko Palangetić, Chris Cornelis, Salvatore Greco, Roman Słowiński

In this paper, we introduce a novel rule induction algorithm called Fuzzy Rough Rule Induction (FRRI).

Discounting and Impatience

no code implementations25 Sep 2023 Salvatore Greco, Diego Rago

Our main purpose is, in practice, to provide a tractable setting within which individual intertemporal preferences can be outlined.

Dominance-based Rough Set Approach, basic ideas and main trends

no code implementations6 Oct 2022 Jerzy Błaszczyński, Salvatore Greco, Benedetto Matarazzo, Marcin Szeląg

Dominance-based Rough Approach (DRSA) has been proposed as a machine learning and knowledge discovery methodology to handle Multiple Criteria Decision Aiding (MCDA).

Fuzzy granular approximation classifier

1 code implementation2 Jun 2022 Marko Palangetić, Chris Cornelis, Salvatore Greco, Roman Słowiński

At the end, we discuss the transparency of the FGAC and its advantage over other locally transparent methods.

Multi-class granular approximation by means of disjoint and adjacent fuzzy granules

no code implementations15 Feb 2022 Marko Palangetić, Chris Cornelis, Salvatore Greco, Roman Słowiński

In granular computing, fuzzy sets can be approximated by granularly representable sets that are as close as possible to the original fuzzy set w. r. t.

A Novel Machine Learning Approach to Data Inconsistency with respect to a Fuzzy Relation

no code implementations26 Nov 2021 Marko Palangetić, Chris Cornelis, Salvatore Greco, Roman Słowiński

Inconsistency in prediction problems occurs when instances that relate in a certain way on condition attributes, do not follow the same relation on the decision attribute.

Supporting decisions by unleashing multiple mindsets using pairwise comparisons method

no code implementations4 Jul 2021 Salvatore Greco, Sajid Siraj, Michele Lundy

With this aim we consider the spanning trees analysis which is a recently emerging idea for use with the pairwise comparison approach that represents the plurality of mindsets (in terms of a plurality of vectors corresponding to different spanning trees).

Explaining the Deep Natural Language Processing by Mining Textual Interpretable Features

no code implementations12 Jun 2021 Francesco Ventura, Salvatore Greco, Daniele Apiletti, Tania Cerquitelli

Despite the high accuracy offered by state-of-the-art deep natural-language models (e. g. LSTM, BERT), their application in real-life settings is still widely limited, as they behave like a black-box to the end-user.

The {0,1}-knapsack problem with qualitative levels

no code implementations12 Feb 2020 Luca E. Schäfer, Tobias Dietz, Maria Barbati, José Rui Figueira, Salvatore Greco, Stefan Ruzika

A variant of the classical knapsack problem is considered in which each item is associated with an integer weight and a qualitative level.

A multiple criteria methodology for priority based portfolio selection

no code implementations13 Dec 2018 Maria Barbati, Josè Rui Figueira, Salvatore Greco, Alessio Ishizaka, Simona Panaro

The multicriteria method permits to compare projects in terms of their priority assessed on the basis of a set of both qualitative and quantitative criteria.

A robust hierarchical nominal classification method based on similarity and dissimilarity using loss function and an improved version of the deck of cards method

no code implementations12 Dec 2018 Ana Sara Costa, Salvatore Corrente, Salvatore Greco, José Rui Figueira, José Borbinha

We propose also a procedure, based on the concept of loss function, to obtain a final classification fulfilling some requirements given by the decision maker and taking into account the hierarchy of criteria and the probabilistic assignments obtained applying SMAA.

Using a new parsimonious AHP methodology combined with the Choquet integral: An application for evaluating social housing initiatives

no code implementations24 Apr 2017 Francesca Abastante, Salvatore Corrente, Salvatore Greco, Alessio Ishizaka, Isabella Lami

We propose a development of the Analytic Hierarchy Process (AHP) permitting to use the methodology also in cases of decision problems with a very large number of alternatives evaluated with respect to several criteria.
