Hey ! Here we are going to discuss on Data Mining…so
basically, you’ve heard a lot about data mining and machine learning in you
know current trends,newspapers, medium.com and so many places but very few
people know what exactly is data mining.
Let’s start with Why Data Mining ?
So basically we are drown with the data it’s like we are
having so much of data and we’re not having knowledge and data mining is basically
a misnormer a lot of people understand data mining in a very wrong way ! Like
if you’re doing a gold mining or coal mining and in those cases you’re actually
digging it for the gold/coal whereas here you’re not you know mining for the
data, you mine for the knowledge ! so the data mining is also known as
Knowledge Mining or Knowledge discovery in data mining and the reason for data
mining being so important is this there is a huge amount of data available.
From terabytes to petabytes.
WHERE IS THE DATA COMING FROM ?
- Social
Media Platforms : Facebook, Instagram etc.
- Ecommerce
: Amazon, Ebay, Flipkart etc.
- Government
: Online records, Aadhar link, Bank transactions etc.
- Society
: News, Blogs and other medias.
So this overall means that there’s a huge amount of data
available. Now only concern is how we can utilize this data to generate some
sort of a knowledge which can be used for decision making, so that is what we
are talking in data mining !
WHAT IS DATA MINING ?
- It
is discovering hidden patterns from already available data.
- Extracting
Knowledge from Data which can be used to make effective decision making.
- Extraction
of interesting (non-trivial, implicit, previously unknown and potentially
useful) patterns or knowledge from huge amount of data.
- Is
it similar to query processing or Search Algorithms?
o
Data mining is not searching or its not even
quering the data.Though it has similarity but it’s way to different.
o
Data mining is applied on various forms of
data, and is applied to find the interesting patterns rather than results from
database.
o
Additional tasks such as Data Preprocessing
etc. are performed in data mining to get effective results.
WHAT CAN BE DATA MINING BE USED FOR ?
- Applications
of data mining are wide and diverse. Initially started as the technique and method to find interesting patterns, now data mining acts as a base to machine learning and Artificial Intelligence applications worldwide.
- Some
basic Applications:
o
Medical fields
o
E-commerce
o
Web page analysis
o
Prediction algorithms in Stock Market, Etc.
WHAT KIND OF DATA CAN BE MINED ?
- Relational
database, data warehouse, transactional database
- Various
IOT sensors data
- Time
series data (Data over the period of time for one particular application)
- Text
Databases such as blogs, tweets, reviews etc.
- Structured,
graph data.
