Customer segmentation using clustering This mini-project is based on this blog post by yhat. Data The dataset contains information on marketing newsletters/e-mail campaigns (e-mail offers sent to customers) and transaction level data from customers. The transactional data shows which offer customers responded to, and what the customer ended up buying. The data is presented as an Excel workbook containing two worksheets. Each worksheet contains a different dataset. %matplotlib inline import pandas as pd import sklearn import seaborn as sns import warnings from sklearn import cluster import numpy as np warnings.

Classifying the “German Credit” Dataset This dataset has two classes (these would be considered labels in Machine Learning terms) to describe the worthiness of a personal loan: “Good” or “Bad”. There are predictors related to attributes, such as: checking account status, duration, credit history, purpose of the loan, amount of the loan, savings accounts or bonds, employment duration, installment rate in percentage of disposable income, personal information, other debtors/guarantors, residence duration, property, age, other installment plans, housing, number of existing credits, job information, number of people being liable to provide maintenance for, telephone, and foreign worker status.

Predicting customer satisfaction Attributes X1 to X6 indicate the responses for each question and have values from 1 to 5 where the smaller number indicates less and the higher number indicates more towards the answer. X1 = my order was delivered on time X2 = contents of my order was as I expected X3 = I ordered everything I wanted to order X4 = I paid a good price for my order X5 = I am satisfied with my courier X6 = the app makes ordering easy for me Y = target attribute (Y) with values indicating 0 (unhappy) and 1 (happy) customers import sys, os import pandas as pd import numpy as np import matplotlib.

Time Series Forecasting Time Series is a big component of our everyday lives. They are in fact used in medicine (EEG analysis), finance (Stock Prices) and electronics (Sensor Data Analysis). Many Machine Learning models have been created in order to tackle these types of tasks, two examples are ARIMA (AutoRegressive Integrated Moving Average) models and RNNs (Recurrent Neural Networks). Data Source For Time series analysis, we are going to deal with Stock market Analysis. [Read More]
