R

Goals and Application
 Survey’s are conducted in each and every industries to
take feedbacks against the customer experience .
 Airline industries are one of the few which takes data
as feedback from customer to provide best facilities
according to customers demand.
 More the number of customer satisfied more will be
the customer taking that particular flights.
 By analyzing the reviews and feedback any airlines can
be benefitted financially by improving their facilities.

Introduction
The data used are the customer experience data which have
been gather from airline industries and further will be used for
proper analysis of the data (Michie, Spiegelhalter & Taylor, 1994).
There are information about feedbacks or review of different
amenities the customer experience.
The target variable consist the values that the particular
customer is satisfied or not which will be used to build machine
learning models and will further be used for prediction purposes
(Wright, 1995).
There are various machine learning algorithms available few of
which are linear regression, random forest classifier, k mean
clustering and many more (Lantz, 2013).

Machine Learning
Machine learning is the recent buzz in the data analysis field. With
the help of different machine learning algorithms prediction is
possible now a days (Hosmer, Lemeshow & Sturdivant, 2013).
The ability to learn from data itself without any human interaction is
what a machine learning called.
Machine learning is classified into 2 different categories-
• Supervised Learning
• Un-supervised Learning
Supervised learning consist of models like regression and
classification.
In supervised learning the input data provided is the labeled data and
the outcomes are known previously (Schmidtler & Borrey, 2011).
