AI's Deep Problem

Artificial intelligence is modeled to some extent on the human brain; and there's a deep problem with this approach. Machine learning is a subset of artificial intelligence (AI) where computer programs automatically learn from data without explicit programming. Inspired in part by the human biology, deep learning is a machine learning method that deploys layers of artificial neurons, called nodes, in an artificial brain called a neural network. Neuroscientists and psychologists have yet to fully understand how the human brain works. Similarly, there's a big problem with deep learning; scientists do not really know exactly how deep learning reaches its decisions.
