§Synthetic Classification Problem
§Description:
The ‘synth.tr’ data frame has 250 rows and 3 columns. The ‘synth.te’ data frame has 100 rows and 3 columns. It is intended that ‘synth.tr’ be used from training and ‘synth.te’ for testing.
§Usage:
synth.tr synth.te
§Format:
These data frames contains the following columns:
- ‘xs’ x-coordinate
- ‘ys’ y-coordinate
- ‘yc’ class, coded as 0 or 1.
