Data Analytics

Today{\uc1\u8217*}s business world is characterized by an unprecedented growth of data, by 2020 we will experience a 300-fold increase from 2005. This data comes in a broad variety of forms: 420 million wearable health monitors are currently in use, more than 4 billion hours of video are watched on YouTube each month and 30 billion pieces of content are shared on Facebook every month. A lot of the data is analyzed in real time: modern cars have about 100 sensors and the NYSE captures 1 TB of trade information during each trading session. However, 1 in 3 business leaders don{\uc1\u8217*}t trust the information they use to make decisions and about 27% of respondents in one survey were unsure of how much of their data was inaccurate. 4.4 million IT jobs have been created globally to support big data. AlphaGo has recently beaten the reigning (human) Go champion.
