Predictive Modeling on the Titanic Dataset

Overview

  • Objective: To predict passenger survival on the Titanic using machine learning algorithms.
  • Dataset: The Titanic dataset, retrieved from Kaggle, contains information about passengers, including features like age, class, and fare.
  • Approach: Employed exploratory data analysis (EDA), decision tree modeling (rpart), and Naive-Bayes Classification.
  • Methodology

  • Data Exploration & Preprocessing:
    1. Conducted thorough EDA using plots and tables to understand data distribution, missing values, and relationships.
    2. Addressed missing values through imputation or removal.
    3. Ensured data quality and consistency.
  • Decision Tree Algorithm (rpart):
    1. Applied the rpart algorithm to predict passenger survival.
    2. Decision trees recursively split data based on features, creating a tree structure.
    3. Evaluated model performance using a confusion matrix
  • Naive-Bayes Classification:
    1. Implemented Naive-Bayes Classification, assuming feature independence.
    2. Evaluated model performance using a confusion matrix.
  • Model Comparison:
    1. Compared accuracy between the rpart model and Naive-Bayes.
    2. Both models exhibited similar accuracy.
    3. The 95% confidence interval confirmed their comparable performance.
  • Conclusion

  • The decision tree and Naive-Bayes models provide reliable predictions for passenger survival.
  • These results demonstrate proficiency in data analysis, modeling, and evaluation.
