Counterfactual Generation with Answer Set Programming

no code implementations6 Feb 2024 Sopam Dasgupta, Farhad Shakerin, Joaquín Arias, Elmer Salazar, Gopal Gupta

In our framework, we show how counterfactual explanations are computed and justified by imagining worlds where some or all factual assumptions are altered/changed.

DiscASP: A Graph-based ASP System for Finding Relevant Consistent Concepts with Applications to Conversational Socialbots

no code implementations17 Sep 2021 Fang Li, Huaduo Wang, Kinjal Basu, Elmer Salazar, Gopal Gupta

We consider the problem of finding relevant consistent concepts in a conversational AI system, particularly, for realizing a conversational socialbot.

Knowledge-Assisted Reasoning of Model-Augmented System Requirements with Event Calculus and Goal-Directed Answer Set Programming

no code implementations10 Sep 2021 Brendan Hall, Sarat Chandra Varanasi, Jan Fiedor, Joaquín Arias, Kinjal Basu, Fang Li, Devesh Bhatt, Kevin Driscoll, Elmer Salazar, Gopal Gupta

We also show how answer set programming (ASP) and its query-driven implementation s(CASP) can be used to directly realize the event calculus model of the requirements.

Constraint Answer Set Programming without Grounding

2 code implementations30 Apr 2018 Joaquín Arias, Manuel Carro, Elmer Salazar, Kyle Marple, Gopal Gupta

The resulting model, s(CASP), can constrain variables that, as in CLP, are kept during the execution and in the answer sets.

Computing Stable Models of Normal Logic Programs Without Grounding

1 code implementation1 Sep 2017 Kyle Marple, Elmer Salazar, Gopal Gupta

We present a method for computing stable models of normal logic programs, i. e., logic programs extended with negation, in the presence of predicates with arbitrary terms.
