Naive Bayes Classifier Using Pyspark

Prerequisite :

• You must have python 3.7 or more installed on your system.

• You must have hadoop and pyspark installed on your system

• You must have a Spyder, Jupyter notebook on your system. Spyder or jupyter notebook come up with anaconda. you just need to launch them after installing anaconda.

• If you work on a google colab no need to install python or Any other IDE, you just need to sign in with google colab and install pyspark using "!pip install pyspark" this command.

• Used a jupyter notebook to build this project.

Skilled required:

• Python programming language

• Basic Statistical analysis skills

• Machine learning concept

What you’ll learn

• How to read the data using pyspark dataframe

• Perform Basic Exploratory Data analysis using pyspark

• How to apply Naive Bayes Classification using pyspark

• How to evaluate the model in pyspark.

Problem Statement or Description:

This project will show how to apply Naive Bayes Classification algorithms using pyspark on a titanic dataset. This dataset contains 11 features:passengerid, age, pclass, name, sex, age, sibsp, parch, ticket, ticket, fare, cabin and embarked. Target columns are the “Survived” column, the passenger is survived or not in the titanic disaster. In this project build the model which will predict if the passenger has survived or not on a testing set.

Key highlights of projects or Essence:

• This project is about classification analysis.

• This project shows you how to read the data and perform some basic Exploratory data analysis using pyspark

• This project shows you how to perform data preprocessing.

• This project shows you how to apply a Naive bayes classification using pyspark.

• At the end of this project, Evaluate the model.
