Here we briefly show how to call the dataset functions in tadasets as well as a simple plotting utility.

[1]:

import tadasets
import matplotlib.pyplot as plt

[2]:

t = tadasets.torus(n=2000, c=10, a=2)
tadasets.plot3d(t)

[2]:

<Axes3D: >

[3]:

t = tadasets.sphere(n=1000, r=4)
tadasets.plot3d(t)

[3]:

<Axes3D: >

[4]:

t = tadasets.swiss_roll(n=2000)
tadasets.plot3d(t)

[4]:

<Axes3D: >

[5]:

t = tadasets.infty_sign()
plt.scatter(t[:,0],t[:,1])
plt.show()

The noise parameter corresponds to the standard deviation of Gaussian noise applied to a dataset. For the above “infinity sign” dataset, we see the efect of noise=0.05 below.

[6]:

t = tadasets.infty_sign(noise=0.05)
plt.scatter(t[:,0],t[:,1])
plt.show()

[7]:

t = tadasets.dsphere(d=1)
plt.scatter(t[:,0],t[:,1])
plt.show()

[8]:

t = tadasets.eyeglasses(n=250,r1=10,r2=5)
plt.scatter(t[:,0],t[:,1])
plt.show()
