Cumulative Scoring-Based Induction of Default Theories

Farhad Shakerin, Gopal Gupta, Michael Wagner
2018 International Conference on Logic Programming  
Our original FOLD algorithm automates the inductive learning of default theories. The enhancements presented here preserve the greedy nature of hypothesis search during clause specialization.  ...  To the best of our knowledge, our FOLD 2.0 algorithm is the first heuristic based, scalable, and noise-resilient ILP system to induce answer set programs.  ...  F I C L P 2 0 1 8 2:4 Cumulative Scoring-Based Induction of Default Theories Algorithm 1 Overview of the FOIL algorithm.  ...

Abductive Knowledge Induction From Raw Data [article]

Wang-Zhou Dai, Stephen H. Muggleton
2021 arXiv   pre-print
Hence, most of them assume the existence of a strong symbolic knowledge base and only learn the perception model while avoiding a crucial problem: where does the knowledge come from?  ...  In this paper, we present Abductive Meta-Interpretive Learning (Meta_Abd) that unites abduction and induction to learn neural networks and induce logic theories jointly from raw data.  ...  The induction learns an abductive logic theory H based on P θ (z|x); the abduction made by H reduces the search space of z.  ...

To adequately model the constructive nature of the physical change propagation process, we base the semantics of the formal- ism on the principle of inductive definition, the main mathematical constructive  ...  Summary: “We give necessary and sufficient conditions for the existence of extensions in a general default theory.

The Pricing Puzzle: The Default Term Structure of Collateralised Loan Obligations

Andreas A. Jobst
2003 Social Science Research Network  
We propose a pricing model that draws on a careful simulation of expected loan loss based on parametric bootstrapping through extreme value theory (EVT).  ...  from the perspective of credit risk in potential collateral default.  ...  None of the existing models has been able to explicate this issue by means of an inductive approach on the basis of simulated default intensity processes.  ...

An experimental evaluation of three theories of auditory stream segregation

Wendy L. Rogers, Albert S. Bregman
1993 Perception & Psychophysics  
Three theories of auditory stream segregation were evaluated. In two-part trials, subjects heard an induction sequence, whose effects upon an immediately subsequent test sequence were measured.  ...  The rhythm and total duration of Induction Sequence tones were varied in two experiments.  ...  Jones (1976) proposed the third theory of streaming: that of rule-based predictability.  ...

Levels of theory-of-mind reasoning in competitive games

Adam S. Goodie, Prashant Doshi, Diana L. Young
2010 Journal of Behavioral Decision Making  
The literature on recursive theory of mind (TOM) reasoning in interactive decision making (reasoning of the type "I think that you think that I think. . .") has been pessimistic, suggesting that adults  ...  This manipulation led to higher-level default TOM reasoning; indeed, reasoning against a lower-level opponent was frequently consistent with assuming the opponent's reasoning to be higher-level, leading  ...  Achievement scores, reflecting proportion of trials that optimized outcomes: (a) default scores and (b) overall scores.  ...

Boosting to correct inductive bias in text classification

Yan Liu, Yiming Yang, Jaime Carbonell
2002 Proceedings of the eleventh international conference on Information and knowledge management - CIKM '02  
We identify the inductive biases of each classifier and explore how boosting, as an error-driven resampling mechanism, reacts to those biases.  ...  Our experiments on the Reuters-21578 benchmark show that boosting is not effective in improving the performance of the base classifiers on common categories.  ...  All parameters were left at default values.  ...

Mortgage Modification and the Decision to Strategically Default: A Game Theoretic Approach

Andrew Collins, David M. Harrison, Michael Joseph Seiler
2012 Social Science Research Network  
To better understand this complex issue, we build a game theoretic model to quantify a number of economic incentives and costs surrounding critical dimensions of the lender's decision to modify a loan  ...  and the borrower's decision to strategically default in an attempt to encourage such a modification.  ...  Defaulting has negative consequences for the borrower, one of which is a reduction in his credit score. 19 We normalize this reduction in credit score rating to an arbitrary value of ' '.  ...

Default Probability Prediction with Static Merton-D-Vine Copula Model

Václav Klepáč
2015 European Journal of Business Science and Technology  
From our and previous results it is obvious that basic Merton model significantly underestimates actual level, i.e. offers low probabilities of default.  ...  Basic Merton structural credit model is based on assumption that firm equity is European option on company assets.  ...  These assumptions allow us to treat the company equity as a European call option with inducted pay-off structure E t = max (V t − L, 0) = (3) = { V t − L, if V t > L (no default), 0, if V t < L (default  ...
