What is …… ?
•
Data Mining
‣
•
computational process of discovering patterns in
large data sets
Big Data
‣
it is the term for a collection of data sets so large
and complex that it becomes difficult to process
‣
data has exponential growth, both structured and
unstructured
How much Data does exist?
•
2.5 quintillion bytes of data are created
EVERY
DAY
•
IBM: 90 percent of the data in the world today were
produced with past two years
•
Forms of Data????
Big Data Examples
•
October 4th, 2012, the first presidential debate
•
Flicker and its photos
Problem…!
•
Data has grown tremendously
•
This large amount of data is beyond the of software
tools to manage
•
Exploring the large volume of data and extracting
useful information and knowledge is a challenge,
and sometimes, it is almost infeasible
HACE Theorem
•
Heterogeneous, Autonomous, Complex, Evolving
•
Big data starts with large volume, heterogeneous,
autonomous
sources
with
distributed
and
decentralized control, and seeks to explore complex
and evolving relationships among data
•
These are characteristics of Big Data
•
This is theorem to model Big Data characteristics
•
Huge Data with heterogeneous and diverse
dimensionality
‣
•
Autonomous sources with distributed and
decentralized control
‣
•
represent huge volume of data
main characteristics of Big Data
Complex and evolving relationships
Data Mining Challenges with Big
Data
•
Big Data Mining Platform
•
Dig Data Semantics and Application Knowledge
I. Information Sharing and Data Privacy
II. Domain and Application Knowledge
•
Big Data Mining Algorithm
I. Local Learning and Model Fusion for Multiple
Information Sources
II. mining from Sparse, Uncertain, and Incomplete Data
III. Mining Complex and Dynamic Data
