Big EDW!

Big Data is changing the way we need to look at Enterprise Data Warehousing. Previously I posted about big data  in Big Data – Volume, Variety and Velocity!. I also posted about the supporting projects from Apache Hadoop, such as Hbase and Hive in Big Data, Hadoop and Business Intelligence. Today...

What is Machine Learning?

Computers and statisticians both can use data, but the way the process is done is completely different. Statistics is about the use of data to enable humans to conclude patterns and gain insight from the data. On the other hand statistical and mathematical models and methods can be applied to produce tools and methodologies for computers. These then are used by the machine to perform the required tasks.

When we teach the computers to give us insight about the data, we teach them to extract information from the data through algorithms in order to identify the patterns from a mass volume of noise. These algorithms, also known as Patten Recognition Algorithms, are also used to automate required tasks, enable us to train the machines to put data into certain contexts using a training set of data.

There are two main types of problems that are solved through the machine learning: classification and regression.

In future posts I will introduce you to some of the methods used in machine learning and their real life applications in Big Data.
