gen_friedman function

Friedman benchmark data

Simulate data from the Friedman 1 benchmark problem. These data were originally described in Friedman (1991) and Breiman (1996). For details, see sklearn.datasets.make_friedman1.

gen_friedman(
  n_samples = 100,
  n_features = 10,
  n_bins = NULL,
  sigma = 0.1,
  seed = NULL
)

Arguments

• n_samples: Integer specifying the number of samples (i.e., rows) to generate. Default is 100.
• n_features: Integer specifying the number of features to generate. Default is 10.
• n_bins: Integer specifying the number of (roughly) equal sized bins to split the response into. Default is NULL for no binning. Setting to a positive integer > 1 effectively turns this into a classification problem where n_bins gives the number of classes.
• sigma: Numeric specifying the standard deviation of the noise.
• seed: Integer specifying the random seed. If NULL (the default) the results will be different each time the function is run.

Note

This function is mostly used for internal testing.
