Supervised and Unsupervised Learning: Data Analytics, Assignment, LU, UK

Task 1: Supervised and Unsupervised Learning

Use the data below for the task

You will need to accomplish the following:

• Perform classification using 3 algorithms, compare and discuss the results of the chosen algorithms.
• Perform regression using 2 algorithms, compare and discuss the results of the chosen algorithms.
• Perform clustering using 2 algorithms, compare and discuss the results of the chosen algorithms.

Perform association rule mining using 1 algorithm and discuss the results (rules generated

For the tasks above, it is also required to do the following:

• Use simple descriptive analytics to analyse the data (e.g. all attributes distribution, outliers).
• Use data exploratory techniques (e.g. three visualisations) to explore the dataset and analyse the results.
• Analyse the results with regards to the dataset properties.

Task 2: Text Mining

For this task, use the link in the Sentiment Labelled file to download the dataset.

Then use one of the text data attached, that is;

•  Amazon
• IMDb  
• Yelp

You will need to accomplish the following:

1. Preprocess the textual data to transform it into a structured format.

2: Explain the changes to the data for each preprocessing method applied.          

3: Use descriptive analytics for feature description of the dataset.

4: Perform clustering using 1 algorithm and discuss the results.

5: Perform classification using 2 algorithms, compare and discuss the results.
