 More information about the dataset

The sonar.mines file contains 111 patterns obtained by bouncing sonar signals off a metal cylinder at various angles and under various conditions. The sonar.rocks file contains 97 patterns obtained from rocks under similar conditions. The transmitted sonar signal is a frequency-modulated chirp, rising in frequency. The dataset contains signals obtained from a variety of different aspect angles, spanning 90 degrees for a cylinder and 180 degrees for a rock. Each pattern is a set of 60 numbers in the range of 0.0 to 1.0. Each number represents the energy within a particular frequency band, integrated over a certain period of time. The integration aperture for higher frequencies occurs later in time, since ...
