چکیده

Most research on computational scientific discovery has focused on developing an initial model, but an equally important task involves revising a model in response to new data. In this paper, we present an approach that represents candidate models as sets of quantitative processes and that treats revision as search through a model space which is guided by time-series observations and constrained by background knowledge cast as generic processes. We demonstrate our system’s ability on three different scientific domains and associated data sets. We also discuss its relation to other work on model revision and consider directions for additional research.

Belief Revision for Inductive Game Theory

Inductive game theory captures how a player inductively derives his/her personal views from experiences. The player may have multiple views, some of which differ from the objective situation, but may revise them with further experiences. This paper gives a logical formulation of this revision process by focusing on the role of player’s beliefs. For this objective, we take the AGM approach of be...

Knowledge acquisition from complex domains by combining inductive learning and theory revision

In the process of knowledge acquisition, inductive learning and theory revision play important roles. Inductive learning is used to acquire new knowledge (theories) from training examples; and theory revision improves an initial theory with training examples. A theory preference criterion is critical in the processes of inductive learning and theory revision. A new system called knowar is devel...

Model Revision from Temporal Logic Properties in Computational Systems Biology

Systems biologists build models of bio-molecular processes from knowledge acquired both at the gene and protein levels, and at the phenotype level through experiments done in wild-life and mutated organisms. In this chapter, we present qualitative and quantitative logic learning tools, and illustrate how they can be useful to the modeler. We focus on biochemical reaction models written in the S...

Revising Process Models through Inductive Learning

Discovering the Business Process (BP) model underpinning existing practices through analysis of event logs, allows users to understand, analyse and modify the process. But, to be useful, the BP model must be kept in line with practice throughout its lifetime, as changes occur to the business objectives, technologies and quality programs. Current techniques require users to manually revise the B...

A Three{tiered Conndence Model for Revising Logical Theories

The task of theory revision in Inductive Logic Programming is to correct the current theory when contradictions with new examples arise. Conndence models are used to assess and compare the diierent alternatives of revising a theory in order to choose the best revision. In this paper, we propose an augmentation of the two{tiered conndence model of MOBAL/KRT that allows to combine diierent heuris...
