Cell phones have become a necessity for many people throughout the world. The ability to keep in touch with family, business associates, and access to email are only a few of the reasons for the increasing importance of cell phones. Today’s technically advanced cell phones are capable of not only receiving and placing phone calls, but storing data, taking pictures, and can even be used as walkie talkies, to name just a few of the available options.
Dataset, The Telenor Case – What do Game of Thrones and Telecoms Have in Common? contains the data of delays in networks (RAVENS). The delays of RAVENS are ranging from 26/07/2018 – 05/08/2018. Each RAVEN_NAME represents the Tower. There are 7847 unique RAVEN_NAMES for different networks like 2G/3G/4G. There are 5 unique families.
To provide optimum solution to business problems we are solving the problem in two steps (i) Data Analysis and coding in PYTHON and (ii) Time Series model building in R Studio.
In data analysis we have found the solutions for the problems and found the number of delays (failures) of RAVENS. We also found the Top_10 RAVENS with and without fails. We also detected the Family names and Member names with most and least fails in networks (failures).
The methods of prediction & forecasting of the problem is done by using Time Series model building. As the name suggests that it involves working on time (years, days, hours, minutes) based on data, to derive the hidden insights to make informed decision making. Time series models are very useful models when it is serially correlated data. Based on mobile data, to predict the four days we have divided the data into train and test .We have done Time series analysis by using Arima, Simple exponential analysis and Recurrent Neural networks (RNN).
Finally we conclude that by considering the Root mean square error for these algorithms, we got RNN (Recurrent Neural Networks) as the best algorithm to predict the future for days. Based on the RNN algorithm the prediction of delays for the next four days were analyzed. We have plotted the graphs based on the Time series model for all the algorithms.
