Data Set Editing by Ordered Projection
1 Department of Computer Science. University of Seville. Spain. {aguilar, riquelme, mtoro}@lsi.us.es Abstract. In this paper, an editing algorithm based on the projection of the examples in each dimension is presented. The algorithm, that we have called EOP (Editing by Ordered Projection) has some interesting characteristics: important reduction of the number of examples from the database; lowe...
متن کاملA Measure for Data Set Editing by Ordered Projections
In this paper we study a measure, named weakness of an example, which allows us to establish the importance of an example to find representative patterns for the data set editing problem. Our approach consists in reducing the database size without losing information, using algorithm patterns by ordered projections. The idea is to relax the reduction factor with a new parameter, λ, removing all ...
متن کاملSet-covering and Editing Discrete Data
This paper describes new set covering algorithms associated with the DISCRETE edit system. DISCRETE is based on the Fellegi-Holt model (JASA 1976) of editing. A new implicit-edit generation algorithm replaces algorithms of Garfinkel, Kunnathur, and Liepins (Operations Research 1986) and Winkler (1995). The new set-covering algorithms correctly generate implicit edits for large subclasses and re...
متن کاملRough Set Analysis of Preference-Ordered Data
The paper is devoted to knowledge discovery from data, taking into account prior knowledge about preference semantics in patterns to be discovered. The data concern a set of situations (objects, states, examples) described by a set of attributes (properties, features, characteristics). The attributes are, in general, divided into condition and decision attributes, corresponding to input and out...
متن کاملAccelerated image reconstruction using ordered subsets of projection data
The authors define ordered subset processing for standard algorithms (such as expectation maximization, EM) for image restoration from projections. Ordered subsets methods group projection data into an ordered sequence of subsets (or blocks). An iteration of ordered subsets EM is defined as a single pass through all the subsets, in each subset using the current estimate to initialize applicatio...
