In this paper we present a system for resolving definite descriptions co-reference in English written texts. The system uses a set of heuristics that identifies different types of definite descriptions. The heuristics development was based on an empirical analysis of definite description use in newswire texts. We developed algorithms for the automatic analysis of several features of each defini...

Let K be a field admitting a cyclic Galois extension of degree n. The main result of this paper is a decomposition theorem for the space of alternating bilinear forms defined on a vector space of odd dimension n over K. We show that this space of forms is the direct sum of (n− 1)/2 subspaces, each of dimension n, and the non-zero elements in each subspace have constant rank defined in terms of ...

Two complementary interval-valued probabilistic reasoning approaches , the incidence calculus proposed by Bundy and the cautious proba-bilistic reasoning method suggested by Quinlan, are analyzed and compared in this study. The correspondences are drawn between the sets of inference axioms employed by each model. In incidence calculus, the set of inference axioms produces the tightest probabili...

Many problems encountered when applying machine learning in practice involve predicting a \class" that takes on a continuous numeric value, yet few machine learning schemes are able to do this. This paper describes a \rational reconstruction" of M5, a method developed by Quinlan (1992) for inducing trees of regression models. In order to accommodate data typically encountered in practice it is ...

This paper describes Rapture | a system for revising probabilistic rule bases that converts symbolic rules into a connectionist network, which is then trained via connectionist techniques. It uses a modiied version of backpropagation to reene the certainty factors of the rule base, and uses ID3's information-gain heuristic (Quinlan, 1986) to add new rules. Work is currently under way for nding ...

It is often necessary to extract simple and understandable rules from databases containing inconsistent records and/or irrelevant elds. In this study we have assessed the feasibility of using a genetic programming (GP) approach to extract a single rule to describe such data. Instead of a tree structure we use a Reverse Polish (postx) representation. To assess the performance of the GP algorithm...

nus paper discusses issues in noise tolerant learning from sensory data. A model driven approach to symbolic learning from noisy data is suggested. Introduction Sensor-driven characteristics of visual objects are rarely noise free and most often quite noisy. "The visual world is noisy. Even well posed visual computations are often numerically unstable, if noise is present in both the scene and ...
