Linear-Time Temporal Answer Set Programming
(Cambridge University Press, 2023)
[Abstract]: In this survey, we present an overview on (Modal) Temporal Logic Programming in view of its application to Knowledge Representation and Declarative Problem Solving. The syntax of this extension of logic programs ...
Automatic depression score estimation with word embedding models
(Elsevier, 2022)
[Abstract]: Depression is one of the most common mental health illnesses. The biggest obstacle lies in an efficient and early detection of the disorder. Self-report questionnaires are the instruments used by medical experts ...
Multiple-Choice Question Answering Models for Automatic Depression Severity Estimation
(MDPI, 2021)
[Abstract] Depression is one of the most prevalent mental health diseases. Although there are effective treatments, the main problem relies on providing early and effective risk detection. Medical experts use self-reporting ...
aspBEEF: Explaining Predictions Through Optimal Clustering
(MDPI AG, 2020-08-28)
[Abstract]
In this paper we introduce aspBEEF, a tool for generating explanations for the outcome of an arbitrary machine learning classifier. This is done using Grover’s et al. framework known as Balanced English ...

Model Explanation via Support Graphs
(Cambridge Univeristy Press, 2024-02)
[Absctract]: In this note, we introduce the notion of support graph to define explanations for any model of a logic program. An explanation is an acyclic support graph that, for each true atom in the model, induces a proof ...
Variable selection in the prediction of business failure using genetic programming
(Elsevier B.V., 2024-04-08)
This study focuses on dimensionality reduction by variable selection in business failure prediction models. A new method of dimensionality reduction by variable selection using Genetic Programming is proposed, which takes ...
Syntactic ASP forgetting with forks
(Elsevier, 2024-01)
[Abstract]: Answer Set Programming (ASP) constitutes nowadays one of the most successful paradigms for practical Knowledge Representation and declarative problem solving. The formal analysis of ASP programs is essential ...
