  • In 2012, debate which is held during president election between Obama & Mitt triggered about 10 million tweets within 2 hours. And the well-known web site Flickr which is used to post our images faced a problem. It receives 1.8 million photographs every day which has the size of 2MB. Approximately they need 3.6TB storage capacity per day. These situations shows the reason for rise of Big Data application

    1. 1. Big Data Mining
    2. 2. Overview  Introduction  Characteristics of Big Data  Big Data and it’s challenges  Big Data mining Tools  Big Data mining algorithm  Applications of Big Data  References  Q&A
    3. 3. Introduction
    4. 4. Interesting Facts  The volume of business data worldwide, across all companies, doubles every 1.2 years (was 1.5 years)  Daily 2500 quadrillion of data are produced and more than 90 percentage of data are produced within past two years.  A regular person is processing daily more data than a 16th century individual in his entire life  In the last years cost of storage and processing power dropped significantly  Bad data or poor data quality costs US businesses $600 billion annually  By 2015, 4.4 million IT jobs globally will be created to support big data (Gartner)  Facebook processes 10 TB of data every day / Twitter 7 TB  Google has over 3 million servers processing over 2 trillion searches per year in 2012 (only 22 million in 2000)
    5. 5. What is
    6. 6. The term Big data is used to describe a massive volume of both structured and unstructured data that is so large that it's difficult to process using traditional database and software techniques. -Webopedia
    7. 7. Characteristics of Big Data Volume - The quantity of data  Variety - categorizing the data  Velocity - speed of generation of data or the speed of processing the data  Variability - Inconsistency  Complexity - Managing the data
    8. 8. DATA MINING CHALLENGES WITH BIG DATA  Main challenge for an intelligent database is handling Big data. The important thing is scaling the large amount of data and provide solution for these problem by HACE theorem
    9. 9.  Challenges Location of Big Data sources- Commonly Big Data are stored in different locations Volume of the Big Data- size of the Big Data grows continuously. Hardware resources- RAM capacity Privacy- Medical reports, bank transactions Having domain knowledge Getting meaningful information  Solutions Parallel computing programming An efficient platform for computing will not have centralized data storage instead of that platform will be distributed in big scale storage. Restricting access to the data
    10. 10. BIG Data Mining Tools  Hadoop  Apache S4  Strom  Apache Mahout  MOA
    11. 11. Hadoop  It is developed by Apache Software Foundation project and open source software platform for scalable, distributed computing.  Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models.  Hadoop provides fast and reliable analysis of both Structured and un structured data.  It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.  Hadoop uses MapReduce programming model to mine data.  This MapReduce program is used to separate datasets which are sent as input into independent subsets. Those are process parallel map task.  Map() procedure that performs filtering and sorting  Reduce() procedure that performs a summary operation
    12. 12. Big Data Mining Algorithm  Big data applications have so many sources to gather information.  If we want to mine data, we need to gather all distributed data to the centralized site. But it is prohibited because of high data transmission cost and privacy concerns.  Most of the mining levels order to achieve the pattern of correlations, or patterns can be discovered from combined variety of sources.  The global data mining is done through two steps process.  Model level  Knowledge level.  Each and every local sites use local data to calculate the data statistics and it share this information in order to achieve global data distribution in their data level.
    13. 13.  In model level it will produce local pattern. This pattern will be produced after mined local data.  By sharing these local patterns with other local sites, we can produce a single global pattern.  At the knowledge level, model correlation analysis investigates the relevance between models generated from various data sources to determine how related the data sources are correlated to each other, and how to form accurate decisions based on models built from autonomous sources
    14. 14. Applications of Big Data  Healthcare organizations can achieve better insight into disease trends and patient treatments.  Public sector agencies can catch fraud and other threats in real-time.  Applications of Multimedia data  To find travelling pattern of travelers  CC TV camera footage  Photos and Videos from social network  Recommender system  Integration and mining of Bio data from various sources in Biological network by NSF (National Science Foundation).  Classifying the Big data stream in run time, by Australian Research council.
