Since ICA is an unsupervised learning, extracted independent components are not always useful for recognition purposes.

Is artificial neural network supervised or unsupervised?

Strictly speaking, a neural network (also called an “artificial neural network”) is a type of machine learning model that is usually used in supervised learning.

How do I know if I am supervised or unsupervised?

The main difference between supervised and unsupervised learning: Labeled data. The main distinction between the two approaches is the use of labeled datasets. To put it simply, supervised learning uses labeled input and output data, while an unsupervised learning algorithm does not.
