چکیده

Feature selection is a data preprocessing step for classi cation and data mining tasks Tradition ally feature selection is done by selecting a mini mum number of features that determine the class label i e by the horizontal compactness of data In this paper we propose a new selection cri terion that aims at the vertical compactness of data In particular we select a subset of fea tures that yields the least number of projected instances while determining the class label A hybrid search that is partially DFS and partially BFS is proposed to exploit the pruning potential of the problem We compare the result induced by C before and after the feature selection

A method for 2-dimensional inversion of gravity data

Applying 2D algorithms for inverting the potential field data is more useful and efficient than their 3D counterparts, whenever the geologic situation permits. This is because the computation time is less and modeling the subsurface is easier. In this paper we present a 2D inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...
