“You know nothing, Jon Snow ……”
is what Ygritte yells to Jon.
Here our situation is also the same as we know nothing about the TELENOR case until we have seen the dataset.
At first, When we heard about the Datathon as beginners, we were very excited to take apart in it.
At finally we received our datasets and here’s our first challenge to import the dataset into the programming platforms,
As we have faced some hurdles to import the dataset as the size of the dataset is around 4GB which has taken some time and put us in the situation :
What we don’t know is what usually gets us killed………………………– Petyr Baelish
we have mentioned above line to express our feeling that we don’t know what’s in the dataset but we want to explore through that.
At last, we are ready to Analysis What do Game of Thrones and Telecoms Have in Common?
At first, when we have gone through the dataset, We have noticed that the Telenor data contains 16 exciting columns with
30091754 jolted rows
When we have gone through the first analysis, we came to know that how complicated the data is, it contains many interesting aspects which we have done through the Exploratory Data Analysis.
Here our main challenge is to predict the fails in the next four days
At First, we have done Exploratory data analysis

After the EDA we need to predict the future four days of delays in mobile data connectivity. To predict the four days delays we use Time Series analysis.
In Time Series Analysis we used three algorithms ARIMA, Simple Exponential Analysis, Recurrent Neural Networks.
We fitted the model with ARIMA and predict the failures of four days and fitted the model using another algorithm Simple Exponential Analysis.
And We used Recurrent Neural Networks for Prediction of failures.
After Fitting the three models using three different algorithms we evaluated by splitting the data into train and test.
We evaluated the best fit model by using the Root Mean Square Error. By considering the RMSE values of the three models, the model with the least RMSE value is taken as the best fit model.
In this case, considering the mobile failure dataset, RNN(Recurrent Neural Network)has the least RMSE value.
So, RNN is taken as the best fit model to predict the future four days of mobile data delays.
Based on the RNN algorithm the prediction of delays for the next four days based on the dataset
are 973776,973725,973674,973623 for 5 ,6,7,8, August 2018 respectively.
