tadasets.infty_sign

tadasets.infty_sign(n: int = 100, noise: float | None = None, angle: float | None = None, seed: int | None = None) → ndarray

Construct a figure 8 or infinity sign with n points and noise level with noise standard deviation.

Parameters:

• n (int, default=100) – Number of data points in shape.

• noise (float, optional) – Standard deviation of normally distributed noise added to data.

• angle (float, optional) – Angle in radians to rotate the infinity sign.

• seed (int, optional) – Seed for random state.

Returns:

data (np.ndarray) – An (n,2) np.ndarray.
