Machine Learning : Pre-processing features
I am participating in this Kaggle competition. It is a prediction problem contest. The problem statement is:
How severe is an insurance claim?
When you’ve been devastated by a serious car accident, your focus is on the things that matter the most: family, friends, and other loved ones. Pushing paper with your insurance agent is the last place you want your time or mental energy spent. This is why Allstate, a personal insurer in the United States, is continually seeking fresh ideas to improve their claims service for the over 16 million households they protect.
Allstate is currently developing automated methods of predicting the cost, and hence severity, of claims. In this recruitment challenge, Kagglers are invited to show off their creativity and flex their technical chops by creating an algorithm which accurately predicts claims severity. Aspiring competitors will demonstrate insight into better ways to predict claims severity for the chance to be part of Allstate’s efforts to ensure a worry-free customer experience.
You can take a look at the data here. You can easily open the dataset in excel and take a look at the variables/features in the dataset. There are 116 categorical variables in the dataset and 14 continuous variables. Let’s start the analysis
Import all necessary modules.

# import required libraries
# pandas for reading data and manipulation
# scikit learn to one hot encoder and label encoder
# sns and matplotlib to visualize
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
from sklearn.feature_extraction import DictVectorizer
import operator
|
All these modules should be installed on your machine. I am using Python 2.7.11. If you have to install these modules, you can simply do

pip install <module name>
Example:
pip install pandas

You might have noticed that we printed the same thing twice. Well, the first time Python prints a small number of columns and the first five observations but the second time it prints all columns and their 5 observations. This is because of the
|
1
2
|
pd.set_option('display.max_rows', None)
pd.set_option('display.max_columns', None)
|
Make sure you have the 5 in head else it will print everything on screen, which will not be pretty. Take a look at the columns present in the train and test set.
|
1
2
|
print 'columns in train set : ', train.columns
print 'columns in test set : ', test.columns
|
There is an ID column in both the data sets which we don’t need for any analysis. Moreover, we will keep the loss column from the training data set into a separate variable.
|

|
# remove ID column. No use.
train.drop('id',axis=1,inplace=True)
test.drop('id',axis=1,inplace=True)
loss = train.drop('loss', axis = 1, inplace = True)
|
Let’s take a look at the continuous variables and their basic statistical analysis.

# high level statistics. mean media mode count and quartiles
# note - this will work only for the continous variables
# not for the categorical variables
print train.describe()
print test.describe()

In many competitions, you’ll find there are some features that might be present in the training set but not in the test set and vice-versa.

In this case, we see that there are not different columns between train and test sets.
Let’s identify the categorical and continuous variables. For this data set, there are two ways to find them:
- variables have ‘cat’ and ‘cont’ in them, defining them
- pandas consider the data type as object

# find categorical variables
# in this problem, categorical variables are start with cat which is easy
# to identify
# in other problems it not might be like that
# we will see two ways to identify this in this problem
# we will also find the continous or numerical variables
## 1. by name
categorical_train = [var for var in train.columns if 'cat' in var]
categorical_test = [var for var in test.columns if 'cat' in var]
continous_train = [var for var in train.columns if 'cont' in var]
continous_test = [var for var in test.columns if 'cont' in var]
## 2. by type = object
categorical_train = train.dtypes[train.dtypes == "object"].index
categorical_test = test.dtypes[test.dtypes == "object"].index
continous_train = train.dtypes[train.dtypes != "object"].index
continous_test = test.dtypes[test.dtypes != "object"].index
|
Correlation between continuous variables
Let’s take a look at correlation between the variables. The idea is to remove variables that are highly correlated.

# lets check for correlation between continous data

# in the other variable. it varies from -1 to 1
correlation_train = train[continous_train].corr()
correlation_test = train[continous_test].corr()
# for the purpose of this analysis, we will consider to variables to
# highly correlation if the correlation is more than 0.6
threshold = 0.6
for i in range(len(correlation_train)):
for j in range(len(correlation_train)):
if (i>j) and (correlation_train.iloc[i,j]>threshold):
print ("%s and %s = %.2f" % (train.columns[i],train.columns[j],correlation_train.iloc[i,j]))
for i in range(len(correlation_test)):
for j in range(len(correlation_test)):
if (i>j) and (correlation_test.iloc[i,j]>threshold):
print ("%s and %s = %.2f" % (test.columns[i],test.columns[j],correlation_test.iloc[i,j]))
# we can remove one of the two highly correlatied variables to improve performance

Let’s take at the labels present in the categorical variables. Although we don’t have any different columns, what may happen is some labels might not be present in one or the other data set.

One Hot Encoding of categorical variables
Encode categorical integer features using a one-hot aka one-of-K scheme. The input to this transformer should be a matrix of integers, denoting the values taken on by categorical (discrete) features. The output will be a sparse matrix where each column corresponds to one possible value of one feature.
- The first way is to use dictvectorizer to encode the labels in the feature.

# cat1 to cat72 have only two labels A and B
# cat73 to cat 108 have more than two labels
# cat109 to cat116 have many labels
# moreover you must have noticed that some labels are missing in some features of train/test dataset
# this might become a problem when working with multiple datasets
# to avoid this, we will merge data before doing onehotencoding
train_test = pd.concat(train, test).reset_index(drop=True)
categorical = train_test.dtypes[train_test.dtypes == "object"].index
# lets check for factors in the categorical variables
for feature in categorical:
print feature, 'has ', len(train_test[feature].unique()), 'values. Unique values are :: ', train_test[feature].unique()
# 1. one hot encoding all categorical variables
v = DictVectorizer()
train_test_qual = v.fit_transform(train_test[categorical].to_dict('records'))
print 'total vocabulary :: ', train_test_qual.vocabulary_
print 'total number of columns', len(train_test_qual.vocabulary_.keys())

new_df2.drop(categorical, inplace=True, axis=1)
# take back the train and test set from the above data
train_featured2 = new_df2.iloc[:train.shape[0], :]
test_featured2 = new_df2.iloc[train.shape[0]:, :]
train_featured2[continous_train] = train[continous_train]

for feature in new_df3.columns:
new_df3[feature] = pd.factorize(new_df3[feature], sort=True)[0]
# take back the train and test set from the above data
train_featured3 = new_df3.iloc[:train.shape[0], :]
test_featured3 = new_df3.iloc[train.shape[0]:, :]
train_featured3[continous_train] = train[continous_train]
test_featured3[continous_train] = test[continous_train]
train_featured3['loss'] = loss

# 4. mixed model
# what we can do is mix these models since cat1 to cat72 just have 2 labels, so we can factorize
# these variables
# for the rest we can make dummies
new_df4 = train_test
for feature in new_df4.columns[:72]:
new_df4[feature] = pd.factorize(new_df4[feature], sort=True)[0]
dummies = pd.get_dummies(train_test[categorical[73:]], drop_first = True)
new_df4 = pd.concat([new_df4, dummies], axis=1)
new_df4.drop(categorical[73:], inplace=True, axis=1)
# take back the train and test set from the above data
