Main Issues with the dataset

1. There is data imbalance between two classes The number of yes(1) is very low in comparison to no(0)

2. Missing Value in the dataset.

Techniques Used

1. Visualizing the data and filling missing value of each column with DecisionTreeClassifier
2. To deal with data imbalance we use SMOTE - Synthetic Minority Over-sampling Technique.
   • SMOTE creates synthetic (not duplicate) samples of the minority class. Hence making the minority class equal to the majority class. SMOTE does this by selecting similar records and altering that record one column at a time by a random amount within the difference to the neighbouring records.
3. Use Logistic regression for training

Result
