When plotted in order (from 1 through 100) as the Y coordinate, the points will create either a Hill (a “bump” in the terrain) or a Valley (a “dip” in the terrain). See the original source for some examples of these graphs. In the original form, there are six files. This is the non-noisy version, with training and test sets merged. ### Attribute Information: 1-100: Labeled “X##”. Floating point values (numeric), the Y-values of the graphs. 101: Labeled “class”. Binary {0, 1} representing {valley, hill} hill-valley active
