Titanic Competition Test

The predictive model in Python for predicting who will survive and who will not on the Titanic using the information of all passengers in a table is based on machine learning techniques and data analysis.

To develop this model, popular Python libraries such as Pandas and Scikit-learn are used. The first step would be to load the Titanic passenger data into a DataFrame using Pandas. Next, an exploratory data analysis would be performed to better understand the characteristics of the passengers and their relationship with survival.

Then, data cleaning and preprocessing would be carried out, including handling missing values, transforming categorical variables into numerical variables, and normalizing the data if necessary. Subsequently, the dataset would be split into training and testing sets.

After preparing the data, a predictive model would be selected and trained, such as a Logistic Regression classifier or a Decision Tree, using the training set. The model would learn to recognize patterns in the data that could help predict passenger survival.

Once the model is trained, its performance would be evaluated using the testing set. Metrics such as accuracy, sensitivity, and specificity would be analyzed to measure the effectiveness of the model in predicting survival.

Once the model has been evaluated and fine-tuned, it could be used to predict the survival of new data, i.e., to determine who might have survived and who did not on the Titanic based on the provided information.

It is important to note that the accuracy of this model depends on several factors, such as the quality and representativeness of the data, as well as the proper choice and configuration of the machine learning algorithm used.
