There are features like the name of the passenger and the cabin which cannot be used for analysis directly.

The Titanic Survival dataset is simple - it contains details of passengers including personal details (name, gender, age, family), passenger details (class, cabin, embarked from, fare of ticket) which are input features, and whether they survived, which is the target feature.

To start with, I will use the RandomForest estimator and see how it does.

Let's divide the train data into x and y now that it has been cleaned and preprocessed.

This is the beginner, introductory Kaggle competition that every new Kaggle member does. Since I had learned a lot of new techniques at the time, I decided to apply them all to this dataset as practice.

The problem with is every step - cleaning, imputation, encoding, feature engineering, etc, is done separately so if a new test sample is given, one cannot directly make a prediction and will have to carry out every step all over again. To solve this, I am going to create a 'preprocessor' class with a transform method that does everything I have done until now and make a pipeline with this preprocessor as the first step and the trained model clf as the second step.

Now that we have cleaned the data into an organized format, we can proceed with preprocessing, i.e., imputing missing values, encoding categorical features and scaling the data if required.
