churn-analysis-ann-model-'s Introduction

Churn Analysis-ANN Model

Overview

In this project, we begin by exploring and visualizing the data. Also, we will build a Customer Churn Prediction Model using artificial neural network.

Customer churn measures how and why are customers leaving the business. We will use telecom customer churn dataset from kaggle (link below) and build a deep learning model for churn prediction. We will also understand precision,recalll and accuracy of this model by using confusion matrix and classification report

PROJECT AIM

To understand and measure how and why customers are leaving the business.

TECHNOLOGIES USED

The Code is written in Python 3.6.9 using google colaboratory. You can go to this link.
You can also use Jupyter Notebook. Touse JupyterNotebook, First, download Anaconda. By downloading Anaconda, you get conda, Python, Jupyter Notebook and hundreds of other open source packages. Now, to install Tensor flow and keras, follow steps below,

# install pip in the virtual environment
$ conda install pip
# install Tensorflow CPU version
$ pip install --upgrade tensorflow # for python 2.7
$ pip3 install --upgrade tensorflow # for python 3.*
# install Keras (Note: please install TensorFlow first)
$ pip install Keras

PYTHON LIBRARIES USED

import pandas as pd
from matplotlib import pyplot as plt
import seaborn as sns
import tensorflow as tf
from tensorflow import keras

DATASET INFO

Dataset is downloaded from Kaggle: https://www.kaggle.com/blastchar/telco-customer-churn
The data set includes information about:
- Customers who left within the last month – the column is called Churn
- Services that each customer has signed up for – phone, multiple lines, internet, online security, online backup, device protection, tech support, and streaming TV and movies
- Customer account information – how long they’ve been a customer, contract, payment method, paperless billing, monthly charges, and total charges
- Demographic info about customers – gender, age range, and if they have partners and dependents
