Preliminary Work In the training dataframe, we observe that the 2 label are slightly balanced (61% labeled as 0). I have not used Linear Regression because it is not a linear model and thus gives an accuracy of just 82%. Our first project will involve one of the most infamous maritime disasters of history: the sinking of the RMS Titanic. In this paper, we explored the Titanic data and four machine learning algorithms namely XGBoost, CatBoost, Decision trees, Random forests were implemented to predict survival rate of passengers. Certainly this model has a scope for lot of improvement and corrections. So far my submission has 0.78 score using soft majority voting with logistic regression and random forest. One of these problems is the Titanic Dataset. Finally, I tried using Random Forests. The target variable here is Survived which takes the value 0 or 1. Kaggle-titanic. I hope . The biggest advantage is that you can meet the Top data scientists in the world through Kaggle forums. What is the distribution of numerical feature values across the samples? * our classifier is complex because of the tree size * our model overfits on the training data in an attempt to improve accuracy on each bucket . And after training i could see a slight improvement in the score, this time it is 0.938. The goal is to find patterns in train.csv that help us predict whether the passengers in test.csv survived. Stuart, Public Domain The objective of this Kaggle challenge is to create a Machine Learning model which is able to predict the survival of a passenger on the Titanic, given their features like age, sex, fare, ticket class etc.. Testing different ML models on famous Titanic dataset from kaggle. The purpose of this challenge is to predict the survivals and deaths of the Titanic disaster at the beginning of the 20th century.
