* Clients Segmentation (Clustering & Classification) ::
* Data preparation: creating of the ABT, ensuring data quality, data cleaning
(imputation and transformation ...)
* Data Analysis : detailed exploratory analysis including correlation and different tests
* Clustering : identifying clusters of customers who have the same behavior within the
same group of clients (using K-means), detailed profiling of the segments for
validation
* Classification : assigning new customers to the clusters that have been created (using
decision Tree)
* The model was built with SAS (Guide and Miner)
* Multi_Sim Users Detection ::
* The goal is be able to identify from some pre-hypothesis, the users who have two sim
providers, include testing the hypothesis, detailed profiling of the target, giving a final
score to each client.
* Model was built with SAS (Guide and Miner)
* Family Communities ::
