Data Science Practice Assignment -

Assignment Task - This assignment consists of two deliverables, being:

• PySpark source code in Jupyter Notebook format. All Jupyter notebook files and the date set file relating to this assignment should be contained within a folder.
• A report. The report must be uploaded as a separate file.

Part I - PySpark source code

Important Note: For code reproduction, your code must be self-contained. That is, it should not require other libraries besides PySpark environment we have used in the workshops.

In this component, we need to utilise Python 3 and PySpark to complete the following data analysis tasks:

1. Exploratory data analysis

2. Recommendation engine

3. Classification

4. Clustering

You need to choose a dataset from Kaggle to complete these tasks. Remember to include the data set file in you source code submission.

Task I.1: Exploratory data analysis

This subtask requires you to explore your dataset by

• telling its number of rows and columns,
• doing the data cleaning (missing values or duplicated records) if necessary
• summarising 3 columns with plots (e.g. bar chart, histogram, boxplot, etc.)

Task I.2: Recommendation engine

This subtask requires you to implement a recommender system on Collaborative filtering with Alternative Least Squares Algorithm. You need to include

• Model training and predictions
• Model evaluation using MSE

Task I.3: Classification

This subtask requires you to implement a classification system on Logistic regression with LogisticRegressionWithLBFGS class. You need to include

• Logistic Regression model training
• Model evaluation

Task I.4: Clustering

This subtask requires you to implement a clustering system on K-means. You need to include

• Model training
• Model evaluation

Part II -Report

You are required to write a report explaining the theory underlining the key concepts around the design and implementation of your code. Finally, you are to include all code in .py format in the appendices of the report. Note that the code will not count towards the word count.

Your report should follow the following template:

Table of Contents -

1.0 Introduction

2.0 Key System Concepts

2.1 Machine learning pipelines. Explain key steps in machine learning pipelines and how they were applied in your code.

2.2 Collaborative filtering. Explain Collaborative filtering principles and how they were applied in your code.

2.3 Logistic regression. Explain Logistic regression principles and how they were applied in your code.

2.4 K-Means. Explain K-Means principles and how they were applied in your code.

3.0 Conclusion

4.0 References

Appendices

Report Format - Your report should be 1000 ~ 1500 words.

The report MUST be formatted using the following guidelines:

• Title Page - Must not contain headers, footers, or page numbering. Include your name as the report's author.
• Header - Report title
• Footer - your name and the page number
• Paragraph text - 12 point Calibri single line spacing
• Headings - Arial in an appropriate type size
• Margins - 2.5cm on all margins
• Page numbering
• Introduction and onwards to use conventional numerals (1, 2, 3, 4) starting at page 1 from the introduction.
• The report is to be created as a single Microsoft Word document (version 2007 or later). No other format is acceptable and doing so will result in the deduction of marks.
