Bases: DownloadARFFGzip

A truncated version of the classic Covtype classification problem.

This should only be used for quick tests, not for benchmarking algorithms.

Number of instances: 581,383 (30m^2 cells)
Number of attributes: 54 (10 continuous, 44 categorical)
Number of classes: 7 (forest cover types)

Forest Covertype (or simply covtype) contains the forest cover type for 30 x 30 meter cells obtained from US Forest Service (USFS) Region 2 Resource Information System (RIS) data.
