sklearn.datasets.make_hastie_10_2

sklearn.datasets.make_hastie_10_2(n_samples=12000, random_state=None)

Generates data for binary classification used in Hastie et al. 2009, Example 10.2.

The ten features are standard independent Gaussian and the target y is defined by:

y[i] = 1 if np.sum(X[i] ** 2) > 9.34 else -1

Parameters:

n_samples : int, optional (default=12000)

The number of samples.

random_state : int, RandomState instance or None, optional (default=None)

If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random.

Returns:

X : array of shape [n_samples, 10]

The input samples.

y : array of shape [n_samples]

The output values.
