Dense rectangles in object-attribute data.
Original language description
We study dense rectangles in data tables with binary attributes, i.e. subtables which are ``almost full of 1's''. Dense rectangles represent interesting patterns which an be thought of as particular granules in data tables. Rectangles which are ``full of1's'' appear as natural patterns in several areas and have been widely studied in computer science and data analysis. Our paper presents a study in which we loosen the criterion of a density of a rectangle. Instead of rectangles full of 1's, we are interested in rectangles which may contain a few 0's. This way, one can capture different kinds of patterns in data. These patterns elude methods which extract only rectangles ``full of 1's''. We propose several ways to define density of a rectangle. We concentrate on column-like (and dually, row-like) conditions which say that a rectangle is dense if each of its columns contains at most a given (small) number of 0's. For this case, we develop theo
