Dataset set is downloaded from analytics vidya hackathon.The data set consist of payment,loan approval,loan amount, credit history of every loan applicants.
The packages are Pandas to load data and to do data analysis, Numpy to work with arrays, scikit-learn is used for building the model and evaluating it, seaborn and matplotlib for data visualisation, pydotplus to visualize the decision tree and finally xgboost model
Exploring the dataset to gain an understanding of the type, quantity, and distribution of data in our dataset. Data analysis is done to check any outliers ,missing values and categorical variables in the dataset. Data visualization is done using seaborn and matplotlib pacakges Outliers are treated using capping and flooring technique
Using scikit-learn train-test split function data set is divided 80% as train and 20% as test.
Using scikit-learn 9 different classification models are built. Logistic regression,LDA,Decision tree, random forest, bagging,Ada boost,gradient boost, xgboost,KNN , SVM classifiers.
We evaluated our built models using the evaluation metrics provided by the scikit-learn package. The evaluation metrics we are going to use are the accuracy score metric, recall,roc_curve, and finally the confusion matrix.
