@theumann one thing is that you have a leak in your setup. You have the Target survived and you also have a string indicating the survival (the solution) in your data. This will lead to a useless model, unfortunately.
Then you seem to only have used the test dataset from the whole titanic dataset from Kaggle (Titanic - Machine Learning from Disaster | Kaggle) with 418 lines. Not sure if this is a deliberate decision.
