Churn in the Telecommunications Industryskewdlogix
Strategic Business Analysis Capstone Project Telecommunications Churn Management
Churn is a significant problem that costs telecommunications companies billions of dollars through lost revenue. Now that the market is more mature, the only way for a company to grow is to take their competitors customers. This issue
combined with the greater choice that consumers have gained means that any adverse touch point with a consumer can result in a lost customer.
Data Mining is a set of method that applies to large and complex databases. This is to eliminate the randomness and discover the hidden pattern. As these data mining methods are almost always computationally intensive. We use data mining tools, methodologies, and theories for revealing patterns in data. There are too many driving forces present. And, this is the reason why data mining has become such an important area of study.

Telecommunication companies today are operating in highly competitive and challenging environment. Vast volume of data is generated from various operational systems and these are used for solving many business problems that required urgent handling. These data include call detail data, customer data and network data. Data Mining methods and business intelligence technology are widely used for handling the business problems in this industry. The goal of this paper is to provide a broad review of data mining concepts.
DATA MINING MODEL PERFORMANCE OF SALES PREDICTIVE ALGORITHMS BASED ON RAPIDMI...ijcsit
By applying RapidMiner workflows has been processed a dataset originated from different data files, and containing information about the sales over three years of a large chain of retail stores. Subsequently, has been constructed a Deep Learning model performing a predictive algorithm suitable for sales forecasting. This model is based on artificial neural network –ANN- algorithm able to learn the model starting from
sales historical data and by pre-processing the data. The best built model uses a multilayer neural network together with an “optimized operator” able to find automatically the best parameter setting of the implemented algorithm. In order to prove the best performing predictive model, other machine learning algorithms have been tested. The performance comparison has been performed between Support Vector
Machine –SVM-, k-Nearest Neighbor k-NN-,Gradient Boosted Trees, Decision Trees, and Deep Learning algorithms. The comparison of the degree of correlation between real and predicted values, the average
absolute error and the relative average error proved that ANN exhibited the best performance. The Gradient Boosted Trees approach represents an alternative approach having the second best performance. The case of study has been developed within the framework of an industry project oriented on the
integration of high performance data mining models able to predict sales using–ERP- and customer relationship management –CRM- tools.

BA is used to gain insights that inform business decisions and can be used to automate and optimize business processes. Data-driven companies treat their data as a corporate asset and leverage it for a competitive advantage. Successful business analytics depends on data quality, skilled analysts who understand the technologies and the business, and an organizational commitment to data-driven decision-making.
Business analytics examples
Business analytics techniques break down into two main areas. The first is basic business intelligence. This involves examining historical data to get a sense of how a business department, team or staff member performed over a particular time. This is a mature practice that most enterprises are fairly accomplished at using.

The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

What types of customers are interested in each of our
products?
What are typical profiles of our customers and how much
value do each of them provide to us
Assessing the current situation
Establishing data mining goals
Developing a project plan including a budget
6. 2 DATA UNDERSTANDING
Selectthe data
Three important issues
Set up a concise and clear description of the problem
Identify the relevant data for the problem description
(The selected variables should be independent of each
other, depends on the method)
Types of data
Demographic data – income, education, gender etc
Socio-graphic data – hobbies, club memberships etc
Transactional data –sales records, credit card spending etc.
Quantitative data – numerical values
Qualitative data – contains nominal and ordinal data
7. SCALES
Nominal – no order between data points - gender
Ordinal – order between data points – ranking
results
Interval – order between data points and equal
distances between measurements – no true zero
point
Ratio – an interval scale with a true zero point –
Sales has doubled - sales previous month 1 milj.,
this month 2 milj.
Question: Is the Likert scale an ordinal or
interval scale?

13. AN APPLICATION EXAMPLE (CRISP – DM)
Topredict which customers would be insolvent early
enough for the firm to take preventive actions
Billing
period was 2 months
Customers used their phone for 4 weeks
Received bill about 1 week later
Payment was due 30 days after receiving the bill
Actions if bill not paid before 14 days after due date.
Phone disconnected if bill exceeded a certain amount
Hypothesis: Customer’s change their calling
behaviour before becoming insolvent
14. EXAMPLE CONT.
Data 100 000 customers
17 month period
Discriminant Analysis, decision trees and neural
networks were used
2066 cases
46 initial variables
Costs were allocated to misclassification errors
Final result:
89.8 % correctly classified with test data and a cost
function = 360 € compared to 14 580 € in the first
run.
