Tabling for non‐monotonic programming
Springer Science and Business Media LLC - Tập 25 - Trang 201-240 - 1999
Terrance Swift
Non‐monotonic extensions add power to logic programs. However, the main logic programming language, Prolog, is widely recognized as inadequate to implement these extensions due to its weak termination and complexity properties. By extending Prolog’s SLD resolution with tabling, Prolog can be improved in several ways. Tabling can allow a logic programming system to compute the well‐founded semantic...... hiện toàn bộ
Automated generation of geometric theorems from images of diagrams
Springer Science and Business Media LLC - Tập 74 - Trang 333-358 - 2014
Xiaoyu Chen, Dan Song, Dongming Wang
We propose an approach to generate geometric theorems from electronic images of diagrams automatically. The approach makes use of techniques of Hough transform to recognize geometric objects and their labels and of numeric verification to mine basic geometric relations. Candidate propositions are generated from the retrieved information by using six strategies and geometric theorems are obtained f...... hiện toàn bộ
On multivariate network analysis of statistical data sets with different measures of association
Springer Science and Business Media LLC - Tập 76 - Trang 83-92 - 2015
Valery A. Kalyagin, Alexander P. Koldanov, Panos M. Pardalos
The main goal of the present paper is the development of a general framework of multivariate network analysis of statistical data sets. A general method of multivariate network construction, on the basis of measures of association, is proposed. In this paper we consider Pearson correlation network, sign similarity network, Fechner correlation network, Kruskal correlation network, Kendall correlati...... hiện toàn bộ
Learning from masked analogies between sentences at multiple levels of formality
Springer Science and Business Media LLC - - Trang 1-25 - 2023
Liyan Wang, Yves Lepage
This paper explores the inference of sentence analogies not restricted to the formal level. We introduce MaskPrompt, a prompt-based method that addresses the analogy task as masked analogy completion. This enables us to fine-tune, in a lightweight manner, pre-trained language models on the task of reconstructing masked spans in analogy prompts. We apply constraints which are approximations of the ...... hiện toàn bộ
Cost-aware sequential diagnostics
Springer Science and Business Media LLC - - Trang 1-17 - 2022
Bernhard Ganter
A simple search problem is studied in which a binary n-tuple is to be found in a list, by sequential bit comparisons with cost. The problem can be solved (for small n) using dynamic programming. We show how the “bottom up” part of the algorithm can be organized by means of Formal Concept Analysis.
A new definition for feature selection stability analysis
Springer Science and Business Media LLC -
Teddy Lazebnik, Avi Rosenfeld
AbstractFeature selection (FS) stability is an important topic of recent interest. Finding stable features is important for creating reliable, non-overfitted feature sets, which in turn can be used to generate machine learning models with better accuracy and explanations and are less prone to adversarial attacks. There are currently several definitions of FS stabil...... hiện toàn bộ
New tractable classes for default reasoning from conditional knowledge bases
Springer Science and Business Media LLC - Tập 45 - Trang 275-291 - 2005
Berilhes Borges Garcia
This paper refines the tractability/intractability frontier of default reasoning from conditional knowledge bases. It presents two new tractable cases with relation to lexicographic entailment. In particular, we have introduced nested conditional knowledge bases and co-nested conditional knowledge bases, which are meaningful conditional knowledge bases. Both tractable classes presented in this pap...... hiện toàn bộ
Logical considerations on default semantics
Springer Science and Business Media LLC - Tập 20 - Trang 195-226 - 1997
William C. Rounds, Guo‐Qiang Zhang
We consider a reinterpretation of the rules of default logic. We make Reiter’s default rules into a constructive method of building models, not theories. To allow reasoning in first‐order systems, we equip standard first‐order logic with a (new) Kleene 3‐valued partial model semantics. Then, using our methodology, we add defaults to this semantic system. The result is that our logic is an ordinary...... hiện toàn bộ
Factorization of fuzzy concept lattices with hedges by modification of input data
Springer Science and Business Media LLC - Tập 59 - Trang 187-200 - 2010
Michal Krupka
We study the problem of reducing the size of fuzzy concept lattices with hedges by means of factorization. As it has been shown previously for the case of fuzzy concept lattices without hedges, the lattice computed by factorization of a fuzzy concept lattice is isomorphic to a fuzzy concept lattice of some other data table. This means that the factor concept lattice can be computed directly as a c...... hiện toàn bộ
On the decentralized coordination of herding activities: a Jadex-based solution
Springer Science and Business Media LLC - Tập 59 - Trang 411-426 - 2010
Gregor Balthasar, Jan Sudeikat, Wolfgang Renz
The AgentContest 2009 provided a revised Cows and Herders scenario which extended the last year’s setting. First, additional environment objects, i.e., fences and switches, were introduced. Secondly, the team score is calculated by the net amount of herded cows at the game end. In this paper we present the design of the multi-agent system (MAS) prototype which participated in this contest and has ...... hiện toàn bộ
