2013 - 1200EB
1EB = 1024 PB = 1 million TB = Over 1 billion GB
Every person on earth can have...
1 PB = 1024TB = Over 1 million GB data
in 3 seconds
Have no idea?
Have you ever heard about it?
Due to unable to deal with all the data at the same time, sampling is an better way to predict a future or confirming a hypothesis.
However, in some cases, only based on samples might get an incorrect result due to it is extremely hard to have an real objective random sampling.
Case Study: Google Flu Trends (H1N1)
While 2009, the deadly flu spread in all over the world. However, CDC(Centers for Disease Control and Prevention) accidentally found that Google have more efficiently, effectively and instantly information than they have.
Google picked out the first 50 million searching key words at the time by Americans
Compared with the data of CDC (Centers for Disease Control and Prevention) on the spread of seasonal flu from 2003 to 2008
Get a list of top 45 searching Keywords
Trace the time and region that most of people searching the information by key in these keywords.
The result could tell where the flu had spread in a almost instantly timing.
Without any physical health examination
Without going to different places
Without long reporting time and human resource
Only by analyzing all data
The result by analyzing samples can only prove that there are certain relation with the hypothesis. About other factors and relations have to held more experiments all over again.
Causality = Find about why
Give an hypothesis
Analyze or Experiment
EX: The Universal Transverse Mercator (UTM) system
It broke the world into 60 zones which make location could now be identified, recorded, and analyzed in a standardized, numerical format. ----- p87. The Big Data
Put information into a form that can be recorded , analyzed and reorganized.
The Big Data
When These Become Data
EX: The data collected by google street view cars
Reuse: Can be use by any other company
Extension: Will be a very good resource for Autonomous Vehicles
The gathered data can improve "Google Map" with data in different field
Google Digitize Book Plan
7 years - Already over 20 million books scanned
Scan and capture book pages into high quality images
Use optical character-recognition software to analyze it into words
Your target clients' favorite places
The shortest path
Autonomous Vehicle more safely
