Big data is so big you need a machine to figure it out.
Data scientists now employ a branch of statistics called “machine learning” to analyze big data sets. And central to this is the algorithm – a computer program designed by humans, then set loose on big data to provide superhuman insights and automated response. Algorithms combined with big data allow us to model the weather, execute stock trades, decode the genome, even sell more toothpaste.
