focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy.
Big data analytics is the use of advanced analytic techniques against very large, diverse big data sets that include structured, semi-structured and unstructured data, from different sources, and in different sizes from terabytes to zettabytes.
