Introduction to Big Data at the IFMSA preGA 2014 Hammamet

2. Data pro capita
double
every 40 months
2.5 exabyte of data was produced daily in 2012
1 exabyte = 23000000000000000000 bits (1019)

6. Gartner: "Big data is high
volume, high velocity, and/or
high variety information that
require new forms of
approaches to make sense of
them"

7. LHC
200 petabyte x year
10 year to decode the first human
genome, now is done in 1 week
Nasa Center for Climate
Simulations stores 32 PB of data
Facebook manage
data for more than
1 billion of users

8. New methodologies for storing,
processing, analyze and visualize
the data.

9. Machine Learning:
• Supervised
• Unsupervised

10. Cluster Analysis

11. Cluster Analysis
Infections diffusion patterns
DNA polymorphisms analysis
Imaging Analysis

12. Useful Material
