Unsupervised Feature Selection Based on Space Filling Concept
The paper deals with the adaptation of a new measure for the unsupervised feature selection problems. The proposed measure is based on space filling concept and is called the coverage measure. This measure was used for judging the quality of an experimental space filling design. In the present work, the coverage measure is adapted for selecting the smallest informative subset of variables by re...
متن کاملSpace-filling Software Visualization
SeeSys TM is a system embodying a technique for visualizing statistics associated with code that is divided hierarchically into subsystems, directories, and les. This technique can display the relative sizes of the components in the system, the relative stability of the components, the location of new functionality, and the location of error-prone code with many bug xes. Using animation, it can...
متن کاملSpace Filling and Depletion
For a given k ≥ 1, subintervals of a given interval [0, X] arrive at random and are accepted (allocated) so long as they overlap fewer than k subintervals already accepted. Subintervals not accepted are cleared, while accepted subintervals remain allocated for random retention times before they are released and made available to subsequent arrivals. Thus, the system operates as a generalized ma...
متن کاملA space-filling curve
In mathematics classes where the natural numbers are studied, several surprising results can be shown about the relative “sizes” of infinite sets, such as the fact the there is a oneto-one mapping between the natural numbers N and the even numbers, showing that they are both countably infinite, with the “same size”. Similar logic also shows that there is a mapping from the natural numbers N ont...
متن کاملSliced space - filling designs
We propose an approach to constructing a new type of design, a sliced space-filling design, intended for computer experiments with qualitative and quantitative factors. The approach starts with constructing a Latin hypercube design based on a special orthogonal array for the quantitative factors and then partitions the design into groups corresponding to different level combinations of the qual...
