3. Introduction
 As the past records show, the number of deaths in
India due to chronic kidney disease (CKD) were 5.21
million in 2008 and this number can be further
raised to 7.63 million by 2020 [4] .
 There is need of detection of the chronic kidney
disease at early stage before getting it worse.
 To reduce mortality rate, an efficient technique is required
to predict and classify it.

4. Need of Study
General Problems :
 A large space is required for complete dataset
 Large computation time
 Not providing good Accuracy
Aim of study:
To predict Chronic Kidney Disease in more accurate and
faster way with reduced attributes.

5. What is Chronic Kidney Disease (CKD)
Structural or functional abnormalities of the kidneys for
>3 months, as manifested by either:
1. Kidney damage, with or without decreased GFR,
as defined by
 pathologic abnormalities
 markers of kidney damage, including abnormalities in the
composition of the blood or urine or abnormalities in
imaging tests
2. GFR <60 ml/min/1.73 m2, with or without
kidney damage; where GFR is Glomerular
FiltrationRate.

7. Data Mining & Classification
 Data mining refers to extracting meaningful
information from hidden patterns of dataset [2].
 The data mining techniques are very useful in health
informatics [16, 17].
 Data mining classification techniques play a vital role
in classifying various diseases from symptoms and
various medical tests.

8. Attribute Selection
 Before inducing a model we almost always do input
engineering
 The most useful part of this is attribute selection (also
called feature selection)
 Select relevantattributes
 Remove redundantand/or irrelevantattributes
 Select the most “relevant” subset of attributes according to
some selection criteria.
Why?

9. Reasons for Attribute Selection
 Simpler model
 Moretransparent
 Easier to interpret
 Faster model induction
 Structural knowledge
 Knowing which attributes are important may be inherently
important to the application
 Reduce storage requirement
What about the accuracy?

10. Attribute Selection Contd…
 Attribute Selection can be done by following two
methods:
 Filter
 Wrapper

11. Filter Method
 Results in either
Ranked list of attributes
 Typical when each attribute is evaluated individually
 Must select how many to keep
A selected subset of attributes
 Forward selection
 Best first
 Random search such as genetic algorithm

12. Wrapper Method
 “Wrap around” the learning algorithm
 Always evaluate subsets
 Return the best subset of attributes
 Use same search methods as before
 Wrapper approach is generally more accurate but
also more computationally expensive
