Homework 6

For any exercise where you’re writing code, insert a code chunk and make sure to label the chunk. Use a short and informative label. For any exercise where you’re creating a plot, make sure to label all axes, legends, etc. and give it an informative title. For any exercise where you’re including a description and/or interpretation, use full sentences. Make a commit at least after finishing each exercise, or better yet, more frequently. Push your work regularly to GitHub, and make sure all checks pass.

For this Homework, conduct a thorough data mining project where you choose an appropriate approach to extract meaningful insights from a provided dataset, addressing a relevant question or problem.

Comprehensive Data Mining Project

Welcome to an engaging and challenging exploration in the world of data mining! In this assignment, you will step into the role of a data scientist, tasked with the exciting responsibility of extracting valuable insights from a complex dataset. Our focus will be on a rich, multifaceted dataset provided by #TidyTuesday—a weekly social data project that offers fresh datasets to the R for Data Science online community.

Objective: Your mission is to comprehensively apply your data mining skills to this dataset. This includes formulating a relevant question or problem, conducting thorough data preprocessing, selecting and implementing the most appropriate data mining techniques, and finally, interpreting the results to provide actionable insights.

This assignment is not just about applying algorithms; it’s about the entire process of data mining – from understanding the problem domain to delivering meaningful conclusions. You will need to make informed decisions at every step, demonstrating not only your technical expertise but also your analytical thinking and problem-solving abilities.

Prepare to dive deep into the dataset, unravel its complexities, and discover the stories hidden within its numbers. Your journey through the intricacies of data mining begins now!


Part 1: Project Planning and Understanding

Task 1: Problem Definition

  • Define the specific problem or research question you plan to address using the dataset.
  • Explain the significance of this problem or question and its relevance to real-world applications.

Task 2: Data Understanding

  • Perform an initial review of the dataset to understand its structure and content.
  • Identify potential challenges, such as missing values or imbalanced data, and propose strategies for addressing these issues.

Part 2: Data Preparation

Task 1: Data Cleaning and Preprocessing

  • Import the dataset and conduct an initial exploration to familiarize yourself with the data.
  • Address missing values and duplicate records, ensuring data quality.
  • Standardize the data types for analysis compatibility.
  • Conduct a preliminary analysis to gain insights into the features and their relationships.

Task 2: Exploratory Data Analysis (EDA)

  • Employ visualization techniques to identify potential clusters or patterns in the data.
  • Select relevant features for clustering based on their potential to reveal insightful patterns.

Part 3: Methodology and Modeling

Task 1: Choice of Techniques

  • Select appropriate data mining techniques (e.g., clustering, classification, regression, anomaly detection) based on the problem definition and data characteristics.
  • Provide a rationale for the chosen techniques and discuss the insights or outcomes you expect to achieve.

Task 2: Model Implementation

  • Implement the chosen data mining techniques using appropriate tools and libraries.
  • Ensure the implementation is aligned with the project objectives and data characteristics.

Task 3: Model Evaluation and Tuning

  • Evaluate the models using suitable metrics to assess their performance.
  • Fine-tune the models as necessary to improve their accuracy and effectiveness.

Part 4: Results, Interpretation, and Conclusion

Task 1: Results Preparation

  • Organize and present your findings in a clear and structured manner.
  • Employ visualizations effectively to highlight key results and patterns.

Task 2: Interpretation and Recommendations

  • Interpret the results within the context of the initial problem or research question.
  • Offer practical recommendations or insights derived from your analysis.

Deliverables: - A comprehensive Jupyter Notebook containing all code, visualizations, and analyses. - A detailed report summarizing the exploratory data analysis, methodology, results, and conclusions.

Submission Guidelines: - Submit your Jupyter Notebook and report via GitHub, ensuring your repository is well-organized and your commit messages are clear.

Grading Rubric: Your submission will be evaluated based on code correctness and completeness, the quality and clarity of visualizations and reports, the adequacy of comments and documentation, and adherence to submission guidelines.
