Learning Structure and Parameters of Stochastic Logic Programs [chapter]

Stephen Muggleton
2003 Lecture Notes in Computer Science  
Previous papers have studied learning of Stochastic Logic Programs (SLPs) either as a purely parametric estimation problem or separated structure learning and parameter estimation into separate phases.  ...  In this paper we consider ways in which both the structure and the parameters of an SLP can be learned simultaneously.  ...  This takes a goal p:G and a labelled clause q:C and produces the labelled goal pq:R, where R is the SLD resolvent of G and C. The answer probability of D S,G is Q(D S,G ) = n i=1 p i .  ...

LGML: Logic Guided Machine Learning [article]

Joseph Scott, Maysum Panju, Vijay Ganesh
2021 arXiv   pre-print
We introduce Logic Guided Machine Learning (LGML), a novel approach that symbiotically combines machine learning (ML) and logic solvers with the goal of learning mathematical functions from data.  ...  LGML consists of two phases, namely a learning-phase and a logic-phase with a corrective feedback loop, such that, the learning-phase learns symbolic expressions from input data, and the logic-phase cross  ...  Introduction to LGML We propose a new method of combining machine learning (the learning-phase) and logic solvers (the logic-phase) in a corrective feedback loop from the logic-phase to the learning-phase  ...

Fuzzy XPath for the Automatic Search of Fuzzy Formulae Models [chapter]

Jesús M. Almendros-Jiménez, Miquel Bofill, Alejandro Luna-Tedesqui, Ginés Moreno, Carlos Vázquez, Mateu Villaret
2015 Lecture Notes in Computer Science  
We re-use a previous method based on fuzzy logic programming where the formula is conceived as a goal whose derivation tree, provided by our FLOPER tool, contains on its leaves all the models of the original  ...  Instead of focusing on satisfiability (i.e., proving the existence of at least one model) as usually done in a SAT/SMT setting, our interest moves to the problem of finding the whole set of models (with  ...  -If & is a conjunction of a certain logic "label" in the original formula, then it is denoted as "&label" in goal F .  ...

Non-termination analysis of logic programs with integer arithmetics

2011 Theory and Practice of Logic Programming  
As a first step towards the analysis of Prolog programs, this paper presents a non-termination condition for Logic Programs containing integer arithmetics.  ...  In first phase, we ignore the outcome (success or failure) of the arithmetic operations, assuming success of all arithmetic calls.  ...  The inference and proof are done in two phases. In the first phase, non-termination of the logic part of the program is proven by assuming that all comparisons between integer expressions succeed.  ...

Employing Learning to Improve the Performance of Meta-RaPS

Fatemah Al-Duoli, Ghaith Rabadi
2013 Procedia Computer Science  
Various forms of memory have been used to achieve this goal and improve the performance of metaheuristics, which warranted the development of the Adaptive Memory Programming (AMP) framework [1].  ...  Similar to most metaheuristics, Meta-RaPS consists of construction and improvement phases. Randomness coupled with a greedy heuristic are typically employed in the construction phase.  ...  The proposed labels are: follow original logic, improve superior solution, or update the values of Meta-RaPS parameters.  ...

Deriving non-Zeno behaviour models from goal models using ILP

2009 Formal Aspects of Computing  
First, a given goal model, formalised in Linear Temporal Logic (LTL), is automatically translated into a (potentially Zeno) Labelled Transition System (LTS).  ...  Identification of Zeno traces is achieved by model checking the LTS model against a time progress property expressed in LTL, while pre-conditions are learned using Inductive Logic Programming (ILP).  ...  peer-00523663, version 1 -6 Oct 2010 Deriving Non-Zeno Behaviour Models from Goal Models using ILP  ...

Goal-conflict detection based on temporal satisfiability checking

Renzo Degiovanni, Nicolas Ricci, Dalal Alrajeh, Pablo Castro, Nazareno Aguirre
2016 Proceedings of the 31st IEEE/ACM International Conference on Automated Software Engineering - ASE 2016  
pre-determined formulations of boundary conditions.  ...  We present a novel automated approach to compute boundary conditions for general classes of conflicting goals expressed in LTL, using a tableaux-based LTL satisfiability procedure.  ...  The second condition states that removing any of the goals no longer results in a logical inconsistency. The third condition prohibits a boundary condition to be simply the negation of goals.  ...

Obstacle analysis is a goal-anchored form of risk analysis whereby exceptional conditions that may obstruct system goals are identified, assessed and resolved to produce complete requirements.  ...  This paper describes a tool-supported technique for generating a set of obstacle conditions guaranteed to be complete and consistent with respect to the known domain properties.  ...  ACKNOWLEDGMENT We are grateful to Bernard Lambeau and the reviewers for their careful inspection and feedback on an earlier version of the paper.  ...

Deriving fold/unfold transformations of logic programs using extended OLDT-based abstract interpretation

Dmitri Boulanger, Maurice Bruynooghe
1993 Journal of symbolic computation  
Given the queried logic program P and the initial goal ~ e(V1,..., V~), a computed answer substitution for the initial goal of P is obtained by restricting the composition of 81...8k to the variables V1  ...  So, in this paper, we propose a general framework for deriving different fold/unfold transformations of definite logic programs. The transformation consists of two phases.  ...  Schreye for pointing out that the method presented in [Boulanger,D.
