 This dataset is described in (Friedman 1991), where it is used to benchmark the multi-variate adaptive regression splines (MARS) algorithm. The signal-to-noise ratio in this dataset is rather low, so it is difficult to rediscover the generating function f(x) especially the terms below the noise level (x4 and x5).

-Variables x01,..., x10 are sampled uniformly from the unit hypercube.
-Epsilon is generated from the standard normal distribution.
