Recently, AI has attracted new attention, in large part due to advances in computer technology. Other important terms used in this context are “machine learning” (ML) which refers to an aspect of AI that uses algorithms to identify patterns in data sets and thereby predict such patterns in other data, and “deep learning” (DL), which is an aspect of ML that mimics the functions of the human brain, with its neural networks. What is implied here is that there are multiple levels within the system, and hence the “deep” descriptor.
