Make a 3D array 2D

import numpy as np
from sklearn.manifold import TSNE

#Make a 3D array 2D
X = np.array([[0, 0, 0], [0, 1, 1], [1, 0, 1], [1, 1, 1]])

model = TSNE(n_components=2, random_state=0)
np.set_printoptions(suppress=True)
result = model.fit_transform(X) 

print( result )

[[ 0.00017599  0.00003993]
 [ 0.00009891  0.00021913]
 [ 0.00018554 -0.00009357]
 [ 0.00009528 -0.00001407]]

Make an n-dimensional array 3D

import numpy as np
from sklearn.manifold import TSNE

#Make a 5-dimensional array 3D
X = np.array([[0, 0, 0, 0, 0], [0, 1, 1, 0, 0], [1, 0, 1, 0, 0], [1, 1, 1, 0, 0]])

model = TSNE(n_components=3, random_state=0)
np.set_printoptions(suppress=True)
result = model.fit_transform(X) 

print( result )
