I was working on one-hot encoding using python. but there is some problem when i run one-hot-encoding
def one_hot_encode(labels): n_labels = len(labels) n_unique_labels = len(np.unique(labels)) one_hot_encode = np.zeros((n_labels,n_unique_labels)) one_hot_encode[np.arange(n_labels), labels] = 1 return one_hot_encode this is what i used to running one-hot endcode
and the data is like this...
[3 3 3 3 3 2 2 2 2 2 1 1 1 1 1]
It occurs this error
"index 3 is out of bounds for axis 1 with size 3"
And i try another path...
change the part of code
one_hot_encode = np.zeros((n_labels,n_unique_labels+1)) This is running but it its not the 3 classes... The result is like this
array([[0., 0., 0., 1.], [0., 0., 0., 1.], [0., 0., 0., 1.], [0., 0., 0., 1.], [0., 0., 0., 1.], [0., 0., 1., 0.], [0., 0., 1., 0.], [0., 0., 1., 0.], [0., 0., 1., 0.], [0., 0., 1., 0.], [0., 1., 0., 0.], [0., 1., 0., 0.], [0., 1., 0., 0.], [0., 1., 0., 0.], [0., 1., 0., 0.]]) how do I fix this problem?
