Formalization of Transformation-Based Learning

چکیده
Research in automatic Part of Speech (POS) tagging has been dominated by Markov Model (MM) taggers. Brill [1, 3, 6], has recently described a transformation-based system with comparable accuracy, and simpler algorithms and representation than MM taggers. We present a set-based formal model of natural language ambiguity and semantic tagging that forms a basis for the generalisation of the transformation-based learning (TBL) and Brill’s TBL tagger [3]. We discuss empirical observations of the training algorithm that suggest a new evolutionary transformation learning strategy may dramatically improve learning time without loss of accuracy. keywords: NLP, Part of Speech Tagging, Machine Learning

Program Development Schemata as Derived Rules
We show how the formalization and application of schemata for program development can be reduced to the formalization and application of derived rules of inference. We formalize and derive schemata as rules in theories that axiomatize program data and programs themselves. We reduce schema-based program development to ordinary theorem proving, where higher-order uniication is used to apply rules...

Abstract Introduction: The concept of organizational learning has become increasingly popular because of organizational need for adaptation to environmental changes. As learning is essential for the people’s growth it is also important for organizations. Since the organizational knowledge is a strategic asset in an organization, organizational learning has been proposed as a vital source of co...
متن کاملFormalization of Fault Trees in Higher-Order Logic: A Deep Embedding Approach
Fault Tree (FT) is a standard failure modeling technique that has been extensively used to predict reliability, availability and safety of many complex engineering systems. In order to facilitate the formal analysis of FT based analyses, a higher-order-logic formalization of FTs has been recently proposed. However, this formalization is quite limited in terms of handling large systems and trans...
متن کاملA Probabilistic Model of Learning Fields in Islamic Economics and Finance
In this paper an epistemological model of learning fields of probabilistic events is formalized. It is used to explain resource allocation governed by pervasive complementarities as the sign of unity of knowledge. Such an episteme is induced epistemologically into interacting, integrating and evolutionary variables representing the problem at hand. The end result is the formalization of a p...
