Revising Regulatory Networks: From Expression Data (2007)
To Linear Causal, S. D. Bay, J. Shrager, P. Langley
Discovering the complex regulatory networks that govern mRNA expression is an important but dicult problem. Many current approaches use only expression data from microarrays to infer the likely...
Ambiguities of global civil society. (2004)
The concept of an emergent global civil society (GCS), an identifiable public sphere of voluntary association distinct from the architecture of states and markets, has become voguish in some...
Lessons learned from data mining applications and collaborative problem solving (2004)
Lavrac, N., Motoda, H., Fawcett, T., Holte, R., Langley, P., Adriaans, P.W.
Smith, S.L., Holland, D., Langley, P.
Errors within height models have, in the past, been communicated in terms of global measures of accuracy for the model. Such quantification ignores the spatial structure of errors across the surface,...
Problems in Building an Instructable Production System. (2002)
Rychener,M., Forgy,C., Langley,P., McDermott,J., Newell,A.
The Instructable Production System project is exploring the incremental growth properties of production systems (PSs) by constructing a generally intelligent problem solving system by gradual...
Approaches to Machine Learning. (2002)
The field of machine learning strives to develop methods and techniques to automatic the acquisition of new information, new skills, and new ways of organizing existing information. In this article,...
Heuristics for Empirical Discovery. (2002)
Langley,P., Simon,H. A., Bradshaw,G. L.
In this paper, the authors review their experiences with the BACON project, which has focused on empirical methods for discovering numeric laws. The six successive versions of BACON have employed a...
The Search for Regularity: Four Aspects of Scientific Discovery. (2002)
Langley,P., Zytkow,J., Simon,H. A., Bradshaw,G. L.
Scientific discovery is a complex activity involving many different components. Our interest in discovery has led us to construct four artificial intelligence systems that address different facets of...
Identifying Solution Paths in Cognitive Diagnosis. (2002)
Consider the problem of describing the thought processes of a human being with respect to how he solves a particular task. How can we infer his knowledge of the task and the procedure or strategy he...
Approaches to Conceptual Clustering. (2002)
Methods for Conceptual Clustering may be explicated in two lights. Conceptual Clustering methods may be viewed as extensions to techniques of numerical taxonomy, a collection of methods developed by...
Discovering Qualitative Empirical Laws. (2002)
Langley,P., Simon,H. A., Zytkow,J. M., Fisher,D. H.
The process of scientific discovery is a complex interplay of many activities, ranging from the discovery of empirical laws through the construction of structural models to explain those laws. This...
Methods of Conceptual Clustering and their Relation to Numerical Taxonomy. (2002)
Artificial Intelligence (AI) methods for machine learning can be viewed as forms of exploratory data analysis, even though they differ markedly from the statistical methods generally connoted by the...
Revising regulatory networks: From expression data to linear causal models (2002)
Discovering the complex regulatory networks that govern mRNA expression is an important but dicult problem. Many current approaches use only expression data from microarrays to infer the likely...
Improved Rooftop Detection in Aerial Images with Machine Learning (2002)
M. A. Maloof, P. Langley, T. O. Binford, R. Nevatia, S. Sage
In this paper, we examine the use of machine learning to improve a rooftop detection process, one step in a vision system that recognizes buildings in overhead imagery. We review the problem of...
Revising regulatory networks: From expression data to linear causal models (2002)
S. D. Bay, J. Shrager, A. Pohorille, P. Langley
Discovering the complex regulatory networks that govern mRNA expression is an important but difficult problem. Many current approaches use only expression data from microarrays to infer the likely...
A Machine Learning Approach to Student Modeling. (1998)
Langley,P., Ohlsson,S., Sage,S.
The notion of buggy procedures has played an important role in recent cognitive models of mathematical skills. The authors review some earlier work on student modeling, in which Artificial...

The geographical incidence of local government revenues: an intraurban case study
The United Kingdom has experienced different local taxation regimes in each of the last three financial years: namely the property-based household rates; the personal community charge or 'poll tax';...
In this paper the detailed patterns of British property valuation and local revenue raising under the council tax are compared with those prevailing under the domestic rates. The results of matching...
Models of trading behaviour and accumulation in stratified housing markets
In this paper the importance of a number of variables and assumptions in relation to subsidy and accumulation in the owner-occupied housing market is examined. First, a theoretical framework is...
