Description

Each record represents 100 points on a two-dimensional graph. When plotted in order (from 1 through 100) as the Y co-ordinate, the points will create either a Hill (a bump in the terrain) or a Valley (a dip in the terrain). There are six files, as follows: (a) Hill_Valley_without_noise_Training.data (b) Hill_Valley_without_noise_Testing.data These first two datasets (without noise) are a training/testing set pair where the hills or valleys have a smooth transition. (c) Hill_Valley_with_noise_Training.data (d) Hill_Valley_with_noise_Testing.data These next two datasets (with noise) are a training/testing set pair where the terrain is uneven, and the hill or valley is not as obvious when viewed closely. (e) Hill_Valley_sample_arff.text The sample ARFF file is useful for setting up experiments, but is not necessary. (f) Hill_Valley_visual_examples.jpg This graphic file shows two example instances from the data.
